Honeywell 10018/E/1 FSC Digital Input Module High-Density I/O

Product Description

Overview

The Honeywell 10018/E/1 is a high-density, 64-channel digital input module engineered for Fail-Safe Control (FSC) systems. Designed for Safety Instrumented Systems (SIS), Emergency Shutdown (ESD), and Fire & Gas (F&G) monitoring, this module ensures reliable and fault-tolerant operation in critical industrial environments. Its Non-Interfering (NI) design isolates each channel, preventing a single fault from impacting the entire rack. The “E” designation indicates a conformal-coated version, offering enhanced protection against moisture, dust, and corrosive contaminants.

Key Features

• 64 isolated digital input channels to maximize rack efficiency

• Conformal coating compliant with ISA S71.04 Class G3 for harsh conditions

• Continuous self-diagnostics to detect stuck-at or wiring faults

• Hot-swappable design for minimal system downtime
