the control signal (4-20mA) is hard wired to pass through the 531 without degradation. In LOCAL mode, the 531 generates the CV (control) signal in AUTO or MANUAL mode. Host CV tracking enables a bumpless transfer to LOCAL mode in either LOCAL AUTO or LOCAL MANUAL mode. A special CV line sense function triggers HOST to LOCAL transfer automatically if host CV signal fails. LOCAL/HOST transfer may also be initiated by a dedicated front panel key or a contact input. The 531's setpoint may be set locally or remotely from the host, ensuring bumpless changeover to LOCAL AUTO mode. The 531 may also be operated as a manual loading station in the LOCAL MANUAL mode. -
The 531 provides automatic PID control backup for critical loops controlled by PLC, DCS or PC systems. Unlike a single loop controller configured to sense and retransmit a control signal, which adds liability and complexity; the 531 has a simple operator interface, special parameters for control states upon host transfer or failure, and a special pass-through circuit that provides redundancy in the control loop. In HOST mode,

The 532 Auto/Manual Station ensures the integrity of your processes with maximum reliability. Isolated inputs and outputs guard against electrical interference, the front face meets NEMA 4X standards for watertight operation, and solid metal housing and sturdy rubber keys enhance durability. The 532 has been engineered to be the industry’s most user friendly and comprehensive Auto/Manual Station. It has three digital display areas, with two offering up to 9 characters of true alphanumerics. The bright, crisp vacuum fluorescent display offers better readability than any other display technology. Additional operator friendly features include: custom programmable alarm messages, keys that illuminate when in use and an easy-to-use menu system. -
The 535 is a 1/4 DIN single loop process controller (SLC) designed to control any analog process variable (temperature, pressure, flow, level, etc.) in batch and continuous processes. The 535’s outstanding feature mix enables it to bring processes under control faster, more accurately and easily than competitive SLC’s, PLC, and PC based control systems. -

5530 SERIES 5-VALVE NATURAL GAS MANIFOLDS
NOSHOK 5-VALVE NATURAL GAS MANIFOLDS are designed for use with differential pressure transmitters incorporating two isolation valves, two equalizing valves and a vent valve for natural gas applications. These valves are available in block, single flange, double flange, or double flange 90° angle connection for remote or direct installation. Flare Pattern™ configurations are optional, which provides maximum clearance for fingers during operation. The soft seat design features a replaceable Delrin® seat with straight through porting for bi-directional flow and easy roddable cleaning*.
*Isolation valves only -
Automatic and accurate control of chlorine in potable and waste water is more important than ever due to health and regulatory concerns. Poor control can lead to failure of biomonitoring tests leading to an even more costly "Toxicity Reduction Evaluation." The 555 is a cost-effective way to upgrade chlorination and dechlorination processes in an easy to use, rugged 1/4 DIN size package. The 555 can be easily set up to handle flow proportional control, residual control, compound loop control with lag times, and dechlorination with sulfur dioxide. -
