The 1-channel IM43-14-SRI trip amplifier

monitors 0/4…20 mA currents or 0/2…10 V

voltages for overshoot and undershoot of limit

values.

The three limit values are set via teach buttons at the front.

Additionally 18 V (at max. 35 mA) are provided for transmitters or sensors.

The measured values are transmitted via a

galvanically isolated analog output to other

devices.

The green LED indicates operational readiness. Three yellow LEDs indicate the switching status of the corresponding output.

The output mode is adjusted via bridges at the

terminals 5…8.

Live-zero signals are converted into dead-zero through bridging terminals 5/9. In live-zero

mode the range between 4…20 mA is monitored. Any state outside this range (< 3.6 mA

or > 24 mA) is signalled with an error message. In this case the power LED will illuminate red, the relays drop off and a fault current of > 22 mA is output. If a faulty transmitter

causes a short circuit, the relays drop off and

a fault current of > 22 mA is output.
