IIC4801 Single Term Current Sensing Controller

Stand-alone / Controllers

This product has been superseded.

Replacement Product: IIC4001 Current Sensing Controller

The Innotech single term current sensing controllers are designed to accept a 4 to 20 milliamp input and to produce a single 0-10V DC control signal output.

The input to the controller can be any temperature, humidity or pressure detector which produces a 4 to 20 milliamp output. The power to the input device can be provided by the controller.

The controller's output can be coupled to auxiliary units such as humidifiers, chilled water valves, damper motors, staging relays and signal selectors which require a 0 to 10V DC control signal..

Models in the IIC4n01 range:

IIC4701 - 4 to 20mA Controller - Direct Acting.
IIC4801 - 4 to 20mA Controller - Reverse Acting.
