IRMA Signal Conditioners


The IRMA signal conditioner accepts RTD or resistance inputs and converts them into a voltage or current output. The output is linearly proportional to the temperature or resistance input. This output is ideal for interfacing to indicators, chart recorders, controllers, or other instrumentation equipment.

The IRMA is DC powered and provides full isolation from the signal input and analog output. The analog output may be configured for one of the following: 0 to 20 mA, 4 to 20 mA, or 0 to 10 VDC.

They can easily be configured using an eight position DIP switch. A simple range setting technique (field calibration) is used so the actual input signal adjusts the output for scaling. This technique eliminates the need for potentiometers which are vulnerable to changes due to vibration.

The unit is equipped with a universal mounting foot and can be mounted to either a top hat (EN 50 022) or a G profile (EN 50 035 – G32) DIN rail.
