ZEN-20C

Extended flexible automation

With the ZEN-20 I/O you get in one unit 12 Inputs and 8 Outputs relays or transistor. Herewith you can do a lot of bigger scale automation whereas the 10 I/O versions are just to short of I/O’s. The 20 I/O unit is available in three different versions starting from C1 with LCD display, control/ program buttons, calendar and clock or C2 with LED status indication or C3 same as C1 but fixed I/O.

ZEN-20C1/C2 expandable up to 44 I/Os
ZEN DC units have analogue input 0-10 VDC
DC models have as well high speed counter 150 Hz.
Expansion available with relay output or transistor output
