Operation Methods
Setting Ranges and Wiring Connections
Connections
Input
Connect the input between terminals V1-COM, V2-COM, or V3-COM, depending on the input voltage.
Malfunctions may occur if the input is connected to unused terminals and the Unit will not operate
correctly.
Power Supply
Connect the power supply to terminals A1 and A2.
Outputs
For a relay output, the SPDT contacts are output on terminals 11, 12, and 14. For a transistor output,
the output is on terminals 11 and 14.
The internal circuit of the transistor output is NPN, but application is possible for either a sinking or
sourcing output.
DIP Switch Settings
The power ON lock time, reset method, drive output method, and operating mode are set using the DIP switch located on the front of the Unit.
Note:
Open the DIP switch cover to set the DIP switch.
Keep the DIP switch cover closed while the power supply to the Relay is ON.
