Schneider Electric RKS Series Single/Dual Transmitter Input Receiver Controllers

Single/Dual Transmitter Input Receiver Controllers
RKS Series

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.

• 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. Model No.
