Selection Notes

The relay-output variant (DC/DC/RLY) switches up to 2 A resistive or 200 W AC lamp loads directly, which suits mixed AC/DC field devices without external interposing relays - the transistor-output DC/DC/DC version would be the choice instead for high-speed PTO/PWM outputs. With 8 of the 14 digital inputs usable for high-speed counting, up to 100 kHz single-phase, this CPU covers basic motion feedback and pulse counting without an added technology module. The 750 KB data memory versus 250 KB program memory split matters for programs with large recipe or logging data blocks.

Applications

Fits compact machine control, mixed AC/DC actuator switching without external relays, and applications needing onboard high-speed counting for encoder or pulse-based feedback.
