COMECO’s signal isolator TRIM is an active triple-isolated transmitter with separate isolated power supply with 1000 VAC isolation level. The input part is internally powered and generates 24 VDC excitation voltage for external devices connected to TRIM input (current loops, transmitters, etc.). The input may accept various mA, mV, V (unipolar and bipolar) as well as resistive linear signals. The output part is internally energized and generates standard or custom specified linear current or voltage (positive or negative) signals. Thanks to the use of high sophisticated electronics for its manufacturing, the TRIM isolator offers some special features that can be activated by the user via internal programming jumpers:
TRIM is available in a case for mounting on a 35 mm DIN rail according to EN50022 and in a convenient 11-pin box for socket mounting.
