Program Relay ZEN
Caution
Product Description
Simple programmable relay.
[Features]
·ZEN, which is ideal for simple control, has been upgraded and renewed.
·Full of functions in a compact body (width 70 mm × length 90 mm).
· A single unit combining relay, timer, counter, and time switch functionality.
· No need to individually wire the timer and relay etc., greatly reducing the amount of wiring steps.
· Multiple-day operation and pulse operation have been added. Time control settings are easy to configure, without complicated programming.
· RS-485 communications types also available as part of the product series. Can remotely monitor the ZEN control status.
· Features a counter function that can count up to 8 digits. The maximum count for DC power supply models is 150 Hz.
· The twin-timer function allows you to set ON and OFF times separately, greatly simplifying repetitive operations. Helps reduce the program capacity.

Model Configuration of OMRON Other Relays
Note 1. Other Relays, Up to 3 expansion I/O units can be connected (excluding economy type CPU units). Note that AC input type expansion I/O units cannot be connected to a DC power supply type CPU unit.
Note 2. Other Relays, The PC connection cable and memory cassette cannot be equipped at the same time.
Note 3. Other Relays, On the LED (no LCD) type, a program cannot be formed with just the CPU single unit, so support software or a memory cassette will be necessary.
