Terminal Arrangement
and Wiring
Install the following M3 crimp terminals on the signal wires and connect to the
terminal block.
Note Tighten the terminal block screws to the specified tightening torque of
0.5 N⋅m.
The following diagram shows the terminal arrangement and wiring for the

Note 1. The V terminals (terminal numbers 4, 5, 6, 7, and 11) are all connected internally.
When I/O power is supplied to terminals 11 and 3, power can be
supplied to output devices from terminals 4, 5, 6, and 7.
When the power supply exceeds 1.0 A, provide an external power supply
to the I/O power supply instead of providing the supply from the terminals.
2. When inductive loads such as solenoids and valves are used, either use
ones with built-in diodes that absorb the back-electromotive force or connect
a diode externally.
The following diagram shows the terminal arrangement and wiring for the
SRT@-OD04-1.
