HIMA F3236 984323602 16‑Channel SIL3 Safety Digital Input Module

Product Description

F3236 (984323602) is a safety‑rated digital input module for HIMA HIMatrix safety instrumented system (SIS). It acquires field discrete signals including emergency‑stop buttons, pressure switches,

level switches and valve position feedback, supports dry‑contact and 6 mA current‑loop input modes. With channel‑level diagnosis and galvanic isolation, it transfers safe‑related status data to HIMA 

safety logic solver. Complies with IEC 61508 SIL 3 safety requirement, supports hot‑swap replacement. Widely used in petrochemical, oil‑gas and power‑plant ESD, F&G and burner‑management 

safety cabinets.
