Split Channel Function Definition

1. 16×24VDC Digital Input Section Collect discrete switch status on site: equipment running feedback, emergency stop signals, on/off valve position confirmation, safety door interlock, flow switch and pressure switch contacts. Each channel is independently optically isolated to eliminate strong electromagnetic interference from frequency converters and high-power motors in the plant field, avoiding false signal triggering.
