SPDT Electric Pneumatic Relay w/ Case & Cover

The CCC-1002 is a pneumatic, proportional control device. Use it with 3 to 15 psi pneumatic transmitters or sensors for controlling valves and actuators in HVAC systems.

Proportional band action, authority, and setpoint are easily adjustable. Single or dual inputs can be used along with an optional remote setpoint adjustment.

The setpoint dial applies to port "1" and is marked from 3 to 15 psi. Adhesive dials (ordered separately) are available to match the ranges of KMC Controls pneumatic transmitters.

With the inputs and features included, it is particularly suit­able for most control applications requiring a receiver controller. (For “low volume” applications, see the CCC-1001 Receiver Controller.)

The CCC-1002 can replace many competitor single/dual-input receiver/controllers such as:

• Barber-Colman (Schneider Electric) RKS-1001/2001/3002/4002
• Honeywell RP908A/RP908B/RP920A/RP920B
• Johnson T-9000 and T-5801/5802
• Robertshaw (Schneider Electric) P341 and 2341
• Siemens 185 and 195 series

(NOTE: An external 28.8 scim restrictor might be required if replacing a receiver/controller using internal restrictors. All transmitters used with the CCC-1002 require an external restrictor.)

Application
The CCC-1002 is designed to work with pressure switches, receiver gauges, relays, and temperature transmitters. Its applications include controlling temperature, humidity, pressure or static pressure, and even flow used in air handlers, boilers, hot water and steam convertors that require single setpoint, reset control, or even remote setpoint. It can be used for setpoint reset in applications such as AHU discharge or mixed air temperature control, boiler water reset control, and steam to water converter (heat exchanger) control.

Features

• Dual inputs
• Remote setpoint adjustment
• Field selectable, proportional, direct or reverse action
• Adjustable throttling range and authority
• Nearly "universal" replacement for single/dual input receiver/controllers
