Double Limit Switch
Overview
For DIN-Rails
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.
