Connecting Control Outputs (outputs 1, 2, 3)
WARNING
Before wiring, or removing/mounting the DCP32, be sure to turn the power
OFF.
Failure to do so might cause electric shock.

Handling Precautions
• When switching small currents, connect a bleeder resistor to allow
current flow of the minimum relay switching input (100 mA min.).
• Current output and voltage output can be selected by setup data
C 76.
Voltage output is reliant on an internal fixed-current circuit.
Set the current value in the setup data so that the optimum voltage is
obtained matched to the conditions of the SSR in use and the load.
Factory setting: general-purpose SSR voltage value.
• Internal connection of MV1 (CH1 MV) and MV2 (CH2 MV), and output 1
and output 2 can be selected in setup data
C44.
• 4 to 20 mA dc and 0 to 20 mA dc can be selected in setup data
C90.
