ZEN Programmable Relays
Ideal for small-scale control applications,
the ZEN provides an economical alternative
to discrete timers, counters and generalpurpose relays. This single unit easily
provides relay, timer, counter, and time
switch functions. Wiring work is greatly
reduced because separate wiring is not
required for devices such as timers and
counters. Programs can be easily written,
saved, and monitored by personal computer.
Programs can also be simulated on the
personal computer without connecting to the
ZEN. Communication models with an RS485
interface allow production line conditions to
be remotely monitored by monitoring the
ZEN control status.
Applications
Designed for use in automation for
commercial and industrial sectors,
ZEN programmable relays provide the
ideal solution for lighting, energy
management, industrial control, watering
and pump control.
