Simple one-touch DIN Track mounting. Built-in timers and counters
so only power supply and I/O circuit wiring required.
Solid wires can be easily connected using only a screwdriver.
Refer to page 33.
I/O capacity can be expanded to up to 24 inputs and 20 outputs by
connecting 3 Expansion I/O Units.
Refer to page 9 and 33.
