Power Supply
24V DC
Note 1
In this configuration the DI Com
and digital inputs are isolated from the
inputs and outputs. The 24V external
power supply can therefore be used to
power transmitters connected to the Zen's
inputs.
Note 2
Each digital input draws 10mA at
24V DC.
Note 3
All cables must be screened,with
screen earthed at one end only.
Note 4
There is no limit to the number of
Zens that can be connected, except that
the power supply and open collector out-
puts must be able to handle the load.
