Designed for General Purpose ,Non-Incendive and Zone 2 applications, TRUNKGUARD Series 200 Device Couplers (TG200) enable fast and easy implementation of fieldbus systems by connecting multiple devices to a main fieldbus trunk in FOUNDATION fieldbus™ H1 and PROFIBUS PA networks. TG200 Device Couplers are available in models that handle four to 20 fieldbus devices.

Device Couplers provide easy and practical mechanisms for implementing fieldbus systems. TRUNKGUARD Series 300 Device Couplers (TG300) simplify the use of fieldbus devices in Zone 1 by allowing “live” access for maintenance and eliminating the need for Exd junction boxes. The TG300 Series offers our patented Automatic Segment Termination feature and a key-operated magnetic interlock which permits one spur at a time to be de-energized and worked on without shutting down the entire segment.

The 330 is a process monitor with universal input that is multi-functional and microprocessor based. The 330 can function as a panel meter and trip (alarm), or as a panel meter with two trips (alarms), analog transmitter and digital transmission with the addition of the RS 485 serial communications option.

The TRUNKGUARD TPS400 Power Supply enables fast and easy implementation of fi eldbus systems by providing properly conditioned power for simplex and duplex FOUNDATION fi eldbus H1 networks. TRUNKGUARD TPS400 is FOUNDATION fi eldbus registered and fully compliant with FF831-1 (the technical specifi cation for fi eldbus power supplies).
-
The TRUNKSAFE Fault-Tolerant Fieldbus System provides a cost-effective, yet highly reliable, strategy to maintain continuous communications between field devices and a host system in the event of any single point failure (such as any open single wire) on a FOUNDATION fieldbus™ H1 or PROFIBUS PA segment.

When wires can’t be run for practical or economic reasons, the WNM Wireless Network Module provides accurate and reliable point-to-point wireless connectivity between remote fi eld sites. The WNM is a bi-directional, spread spectrum radio modem that delivers the fl exibility and cost-saving advantages of wireless data transmission. It is ideal for use with Moore Industries’ NET Concentrator System® (NCS), as well as other SCADA and distributed I/O systems.
