Digital Outputs
Wiring Power Supplies
1. Connect the "positive" lead to the “V1” terminal for the relay outputs, to the “V2” terminal for
the transistor outputs.
2. In both cases, connect the “negative” lead to the “0V” terminal of each output group.
„ In the event of voltage fluctuations or non-conformity to voltage power supply specifications, connect the
device to a regulated power supply.
„ Do not connect the ‘Neutral’ or ‘Line’ signal of the 110/220VAC to the device’s 0V pin.
Relay Outputs
„ The 0V signal of the relay outputs is isolated from the controller’s 0V signal.
Increasing Contact Life Span
To increase the life span of the relay output
contacts and protect the device 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.
