Wiring the Output Power Supply
 A non-isolated power supply can be used provided that the 0V signal is connected to the earth ground.
 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.
 The adapter 0V and the I/O 0V must be connect to the same line, Ignoring this may damage the device.
Wiring Transistor Outputs
 Output 32 can be wired either as pnp (source) or npn (sink). pnp and npn can be used simultaneously.
 Output 32 can be used as a high speed output.
pnp (source) outputs 32-39
pnp (source) outputs 40-47

Wiring the Power Supply
Connecting RG Pins
For correct operation of digital and analog inputs and for EMI immunity, connect the RG pin of all the expansion modules
containing RG signals to the adapter module 0V signal.
 The overall length of the wire connecting the RG pins to the adapter 0V signal must be less than 3 meters.
 Connect the RG pins in series (daisy chain). To facilitate this, use both the RG pins.
