INPUT/OUTPUT MODULES, RESISTANCE

Resistance Input Modules
Intended for applications where an existing resistance signal need to be monitored by a DDC-controller.

The module converts either a 135 ohm or 1000 ohm signal to a 0-10Vdc signal.

An on-board potentiometer enables the output to be correctly calibrated to the input for ease of commissioning.

Resistance - Output Modules, 135 ohm or 1000 ohm
Intended for applications where new or existing plant requires a 135 ohm or 1000 ohm potentiometric control signal.

The ROC converts a 3-wire resistance signal to an analog output, using current loop power (two wire).

The ROC is reverse polarity protected and offers linear tracking of a 3-wire resistance input against the standard output signal of a 4 to 20 milliamp (current source).

Its small size and self-powered feature lends its use to remote mounting for feedback signals from a valve or damper motor indicating its position.
