Single/Dual Transmitter Input Receiver Controllers
Model Chart
Specifications
For use in conjunction with remote proportional
transmitters for proportional control of pneumatic
actuated dampers, valves, etc., in air conditioning
systems. The transmitter-receiver-controller
system may be used to control temperature,
humidity, or pressure.
Features:
• Nozzle and flapper relay-type receiver controllers.
• Linear, stable and responsive.
• Models available for one, two or three inputs.
• Mounting provided for two (1/8 NPT) 1-1/2 in.
stem-mounted receiver-gauges and two 1-1/2 in.
stem-mounted pressure gauges.
• Barbed fittings for 1/4 in O.D. plastic tubing.
• Setpoint scales available to match transmitter ranges.
