Analog Outputs
Transistor Outputs (pnp)
The 0V signal of the analog input and output must be connected to the controller’s 0V.
Power Supply
The controller requires an external 24VDC power supply.
A non-isolated power supply can be used if a 0V signal is connected to the chassis.
Install an external circuit breaker. Guard against
short-circuiting in external wiring.
Double-check all wiring before turning on the
power supply.
Do not connect either the ‘Neutral or ‘Line’ signal
of the 110/220VAC to 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.
Earthing the Power Supply
To maximize system performance, avoid electromagnetic interference by:
Mounting the controller on a metal panel.
Earthing the controller’s power supply: connect one end of a 14 AWG wire to the chassis
signal; connect the other end to the panel.
Note: If possible, the wire used to earth the power supply should not exceed 10 cm in length.
However, it is recommended to earth the controller in all cases.
