The USS123  is functional equivalent of the MCAS3-3 module, which converts analog input signal 0 - 10V to four discrete output states. The module has three relays with SPST-NO contacts. Built-in hysteresis circuit prevents contacts from "flickering" in switching points. LED diodes indicate output states according to the table:

UWE rising [V]	UWE falling [V]	S1	S2	S3
0	0
3,9	3,2
6,9	6,2
9,9	9,2

- opened contacts   - closed contacts
