Wiring the Outputs’ Power Supply
Wiring DC supply
1 Connect the "positive" cable to the "+V" terminal, and the “negative” to the "0V" terminal.
„
A non-isolated power supply can be used provided that a 0V signal is connected to the chassis.
„
Do not connect the ‘Neutral’ or ‘Line’ signal of the 110/220VAC to the device’s 0V pin.
„
In the event of voltage fluctuations or non-conformity to voltage power supply specifications, connect the
device to a regulated power supply.
Notes:
1. The adapter and output’s power supply must be connected to the same 0V signal.

Increasing Contact Life Span
Both modules have 8 relay outputs. To increase the life span of these contacts and protect the module from
potential damage by reverse EMF, connect:
„
a clamping diode in parallel with each inductive DC load,
„
an RC snubber circuit in parallel with each inductive
AC
load.
