VANTAGE 4800
Single & Multipath Spool Construction. The Engineering Team at Eastech believed that in order to absolutely meet all of the requirements of AWWA/ANSI C750–03, a flowmeter had to be designed that not only adhered to every section of the Standard, but also eliminated any possibility of improper installation, inaccurate velocity measurements, and less than adequate calibration procedures. A flowmeter, in order to meet these requirements, would have to possess the following features:
Factory aligned spoolpiece sensors for guaranteed installed accuracy
High accuracy flow measurement under disturbed flow profiles
Advanced electronic meters with onboard dataloggers
NIST traceable calibration under actual operating conditions

Moore Industries’ universal SLD PC-Programmable Functional Safety Loop Display features a large integral display that shows real-time process status in mA, percent, or any designated 5-character Engineering units (EGU). The SLD is part of Moore Industries’ FS Functional Safety Series products. It is certified by exida as a SIL3 capable, non-interfering device for use in a safety loop. The SLD Functional Safety Programmable Loop Display is the perfect solution to accurately and reliably display process status in a safety loop:Features:
-
SIL3 Capability. The SLD is certifi ed by exida for non-interference in a safety loop. (It is not SIL3 assessed or certifi ed to be used as part of the safety function).
-
Easy-to-read, customizable display. The SLD’s independently confi gured display features two rows of large characters that can be clearly read in the fi eld and set to display any EGU.
-
360° fl exible mounting. When placed into one of our housings, the SLD can be mounted at any angle in nearly any environment.
-
Low voltage drop. Loop-powered by less than 2.3 Volts, the SLD can even be installed on burdened loops.
-
Loop Maintenance Zener Diode Option. Allows the SLD to be removed from the loop for maintenance without interrupting your safety function.
-
Custom and square root curves. Select a square root or linear curve from the library, or create your own. Use our software to input a table in one EGU and have the PC program convert it into a different EGU for display.

SRM FS FUNCTIONAL SAFETY RELAY MODULE
SRM Safety Relay Module provides a high level of availability for safety-critical applications and as a part of Safety Instrumented Systems (SIS). It has been developed following the IEC 61508 standard and is certified by exida for single use in Safety Instrumented Systems up to SIL 2. The SRM is a relay repeater model that accepts a single contact closure input from a logic solver trip output such as the Moore Industries STA Safety Trip Alarm or the SPA2 Programmable Limit Alarm Trip. The SRM provides three contacts per alarm input, allowing you to add alarm contacts for your safety processes without special installation or configuration. Force Guided Relay Unlike traditional multi-output off-the-shelf interposing relays, the SRM is built using a safety-rated relay with forcibly-guided contacts. This design is commonly used in control and safety systems where the logic of an application needs to detect the state of the output contacts. This is achieved by monitoring the state of the monitor contact that is also mechanically linked to the same armature as the output contacts. A Force Guided Relay avoids the possibility of having contacts stuck in the Normally Open (NO) and Normally Closed (NC) states at the same time. Also known as a Positively Guided Relay, the Force Guided Relay assures users that mechanical problems such as welded contacts won’t be missed. Rugged Housing The SRM is housed in a DIN case that can be mounted on 35mm Top-Hat DIN-rail. The aluminum housing is more rugged and durable than safety relays housed in a plastic case.Features:
- exida certified to IEC 61508. exida has certified the SRM for single use in a Safety Instrumented System up to SIL 2.
- Comprehensive FMEDA certified safety data.Upon request, exida-certifi ed FMEDA (Failure Modes, Effects and Diagnostics Analysis) data is provided to be used by a competent functional safety practitioner to determine the SRM’s applicability in specific safety-related applications.
- Visual diagnostic information. Front-panel LEDs provide diagnostic information, with three LED indicator lights that show the Input, Output and Power status. The panels provide an instant visual diagnostic on the SRM, setting users quickly see if there are any potential problems.
- Easy to install and configure. The SRM can be installed in a Safety Instrumented System with minimal wiring. Simply provide a contact closure input to the SRM and you get three process relay outputs. A monitor relay is also provided.
- Input Snubber. The Contact Closure input circuit includes an internal snubbing diode across its relay coil, meaning there is no need for external suppression across the input terminals.
- Fuse protection. Input power and all four relay outputs on the SRM are fuse protected.
- RFI/EFI protection. Enhanced RF immunity up to 20V/m, 20-1000MHz when tested to IEC 61000-4-3.

SSX/SST Safety Series Isolator & Splitter
FS Functional Safety Series, the exida® approved, SIL 3 capable 2-wire (loop powered) SSX and 4-wire (line/mains powered) SST Safety Isolators and Splitters provide isolation and signal conversion for your SIS (Safety Instrumented System) needs. These units protect and enhance loops and also pass valuable HART® data from the field transmitter to host systems and vice-versa.Isolate your SIS from your Basic Process Control System or monitoring system so disconnections or failures to these secondary systems don’t affect your safety system. FMEDA (Failure Mode Effects and Diagnostic Analysis) reports are available with the required safety data to ensure that risk reduction requirements are met.Protect your safety system from surges, spikes and transients in the field. With 1500Vrms isolating capability, the SSX/SST protects your safety I/O cards and system from the rigors of plant environments.With built-in HART pass-through technology you can rest assured that when your loops use HART transmitters that critical and valuable HART diagnostic, process, and calibration information can be read on either side of the SSX/SST. Most all other isolators block and “strip off” the HART signal.Features:
- exida certified IEC 61508:2010. exida has certified the SSX/SST for use in an SIS up to SIL 3 in monitor mode, where only the input circuit is part of the safety function. For single use mode, the SSX/SST is approved for use in an SIS up to SIL 2.
- Comprehensive FMEDA certified safety data. Upon request, exida-certified FMEDA data is provided to be used by a functional safety practitioner to determine the SST’s and SSX’s applicability in specific safety-related applications.
- Valuable HART data not lost. Both the SSX and SST pass critical HART data to asset management systems, programming devices or host systems.
- Split signals between two locations. The 4-Wire SST takes in one signal and gives you two fully isolated outputs that can be taken to two separate receiving devices. This facilitates maintenance on either output loop without losing the signal on the other output loop.
- RFI/EMI Protection. Standard 20V/m protection offered to protect against harmful effects of radio frequency and electromagnetic interference.
- Transmitter excitation. The 4-wire SST is capable of providing loop power to a 2-wire transmitter that is connected to its input.
