1.Main Functions

Provides 32‑channel 24 VDC digital signal acquisition, receives binary on‑off status signals from field switches, proximity sensors and interlock devices, converts field‑side hardware status into internal bus‑compatible digital data for controller processing.
Supports both sinking / sourcing input modes, compliant with IEC 61131‑2 industrial sensor input standard. Each channel is equipped with configurable hardware filter to suppress on‑site electromagnetic interference and signal jitter.
Implements group‑based galvanic isolation between field input circuits and internal system bus, protects back‑end controller from surge voltage and ground loop disturbance, improves system anti‑interference performance.plcva.com
Communicates with main CPU controller via back‑plane bus or fieldbus, transmits real‑time channel status, alarm information and diagnostic data to upper control unit.
LED status indicators for power supply, module running state and each input channel, for quick on‑site hardware troubleshooting.
Built‑in module self‑diagnosis function, detects power abnormality, channel short‑circuit and communication failure, reports fault codes to host control system.
35 mm DIN‑rail mounting design; operates under industrial cabinet temperature range 0 ℃ ~ +60 ℃, meets CE‑EMC requirements for heavy‑industry environment.

SAC‑IN32 Digital Input Module

SAC‑IN32 Digital Input Module

Used in PLC / DCS distributed automation control cabinets for digital‑status collection of field‑site equipment.plcva.com
Collects feedback signals of limit switches, emergency‑stop buttons, valve position feedback, motor running status, relay contact status and photoelectric sensor signals in production lines.
Widely deployed in metallurgy, papermaking, chemical industry, water treatment, power‑plant auxiliary control and general manufacturing automation projects.
Expands digital input capacity of automation system; cannot work independently, must cooperate with matched main controller, power supply unit and system back‑plane bus.
Serves as spare‑part replacement for existing running automation systems for equipment maintenance and renovation.
