Overview

The Honeywell 51120673‑101 is a versatile universal channel module compatible with TDC 3000 and Experion PKS systems. It provides mixed-signal I/O functionality, allowing each channel to operate as analog input, analog output, digital input, or digital output. Moreover, it supports high-resolution measurements, precise control, and reliable integration into industrial process automation environments.

Key Features

• Universal I/O Flexibility: Each channel can be independently configured as AI, AO, DI, or DO.

• High Accuracy: 16-bit resolution ensures precise analog measurement and control.

• Noise Immunity: Electrical isolation between channels enhances reliability in harsh conditions.

• Diagnostics: Built-in monitoring reduces system downtime and simplifies maintenance.

• Compact Design: 16 channels fit into a single module, saving valuable panel space.

• Certified Safety: CE, UL, TUV, and CSA approvals ensure industrial compliance.
