Configurable Double Limit Switch COM 90
General Description
This module contains two comparators and one or two relays for the
monitoring of analog signals from 0-400 mV, 0-10 V or 0-20 mA.
Input range and operating mode may be selected via DiL-switches.
Two switching thresholds with status LED’s, adjustment via a 12-
turn potentiometer

General
These DIN-rail modules possess two front-plate potentiometers for the two thresholds and three status LEDs, input
values below “low” threshold, between “low” and “high” (window) and above “high”. The optional relay has tree
2.8mm flat connectors on the top of the module, for which corresponding screw terminal connectors are available
(type lmi 205 203 01).
Upon request, relay 2 can also be connected between screw terminals 5 and 6 (instead of the flat connectors). In
that case only two single contacts are available for each relay.
