The 1-channel IM43-13-R trip amplifier 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 the lateral ro tary coding switches. Additionally, 18 V (with max. 35 mA) are pro vided for transmitters or sensors. Edition • 2023-02-23T13:05:16+01:00 1 / 3 The green LED indicates operational readi ness. Three yellow LEDs indicate the switch ing status of the corresponding output. The output mode of the relays and the hys teresis are set via DIP switches.
