Honeywell 16159/1/1 Digital Input Module

The Honeywell 16159/1/1 Digital Input Module is an industrial-grade I/O component designed for use in Honeywell’s distributed control systems (DCS), particularly the TDC 3000 and Experion Process Knowledge System (PKS). This module enables real-time monitoring of field devices by receiving and interpreting digital signals from switches, sensors, and other binary devices.

Engineered with reliability and durability in mind, the 16159/1/1 module ensures consistent performance even in demanding process environments such as refineries, chemical plants, power stations, and manufacturing lines. It is used extensively in applications where input status tracking, interlocking, alarm monitoring, and sequencing are critical to the safety and continuity of operations.

Its compact size, field-proven robustness, and seamless integration into Honeywell DCS architectures make it an indispensable asset in industrial automation and control.
