Product Overview

The Honeywell 621-2201 Isolated Output Module is designed for distributed control systems like TDC 2000 and TDC 3000. It provides safe and reliable digital output signals to field devices using optical isolation. This module is ideal for SCADA, SIS, and process automation environments that demand robust signal integrity and fault protection.

Technical Specifications

Performance and Integration

The 621-2201 supports eight isolated digital outputs, each protected by optical isolation to prevent ground loops and electrical interference. It integrates seamlessly into Honeywell’s control platforms, supporting real-time switching of actuators, relays, and solenoids. Its design ensures that field devices operate with high integrity, even in electrically noisy environments.

Design and Reliability

Honeywell engineered the 621-2201 with industrial-grade components and certified it to CE and RoHS standards. Its compact 0.63 kg form factor fits standard enclosures, while LED indicators provide quick diagnostics for each output channel, simplifying troubleshooting and maintenance.

Application

The Honeywell 621-2201 Isolated Output Module is ideal for applications in process automation, SCADA, and Safety Instrumented Systems (SIS). It is especially well-suited for environments where electrical isolation is required for safe signal transmission, such as in oil and gas, chemical processing, and power generation industries.
