Supply and I/O configuration
Rated supply is 110 to 240 V AC/DC at 50/60 Hz — the same rail voltage that powers many control transformers and distribution blocks in a panel, so no separate 24 VDC power supply is needed for the basic unit. Four digital inputs and one relay output are integrated on the basic unit.
