Technical Specifications Model: ICSI16E1 Signal Type: 24 V DC digital input Channel Quantity: Multi‑channel digital input Galvanic Isolation: Group‑wise isolation Mounting Style: Control rack plug‑in module Power Supply: From rack back‑plane bus Operating Temperature: 0 ℃ to +60 ℃ Storage Temperature: ‑40 ℃ to +85 ℃ Relative Humidity: 5‑95 %, non‑condensing Protection Class: IP20 Certifications: CE
Functional Features High‑density multi‑channel 24 V DC discrete signal acquisition for field switches and sensors. Group‑wise galvanic isolation eliminates ground‑loop disturbance from field side. Front‑panel LED indicators directly reflect real‑time on‑off status of each input channel. On‑board self‑diagnosis monitors back‑plane power supply and internal circuit hardware fault. Supports authorized hot‑swap operation under system maintenance workflow.
Application Scenarios Spare‑part replacement for ICSI16E1 digital input module in industrial control rack. Signal collection for limit switches, proximity switches, relay auxiliary contacts in process industry. Discrete status acquisition hardware for power, chemical and manufacturing automation systems.
Installation Requirements Insert ICSI16E1 into designated rack slot and lock side locking buckle. Complete connection between module and corresponding field termination hardware. Implement protective earthing complying with automation system grounding specification. Reserve ventilation heat‑dissipation clearance around module slot.
Usage Notes Field signal cables adopt shielded twisted‑pair and implement single‑point shielding earthing. Do not apply voltage exceeding 24 V DC rated signal range to input channels. Periodically inspect connection status and remove cabinet dust accumulation.
