The USS111  is functional equivalent of the MCE3 module, which converts three analog signals 0 - 10V to three independent discrete output states. The module has three relays: one SPST-NO and two SPDT contacts. Built-in hysteresis circuit prevents contacts from "flickering" in switching points. LED diodes indicate output states according to the table:

WE S1, S2, S3 rising [V]	WE S1, S2, S3 falling [V]	S1	S2	S3
0	0
3,0	2,5

- opened contacts   - closed contacts
