Product Overview
The HIMA F3236 is a safety‑certified 16‑channel digital input module for HIMatrix safety PLC systems. It acquires discrete status signals from field devices including potential‑free dry contacts and 6 mA current‑loop sensors, transmits safety‑validated data to the safety controller via internal system backplane bus. Each channel supports wire‑break diagnostics for field wiring fault detection. Equipped with per‑channel LED status indicators, hot‑swap function allows online replacement without system shutdown. Widely deployed as spare replacement for existing ESD, F&G and burner management safety installations in process plants.
