Honeywell 621-2100 Digital Output Module

The Honeywell 621-2100 Digital Output Module is an AC output module for Honeywell IPC 621 control systems. It provides eight output channels for switching field devices operating on 115 VAC power. The module combines isolated output circuitry, built-in protection, and per-channel status indication for industrial control applications.

Output Characteristics

The module provides eight digital output channels rated for 115 VAC operation. Each output can switch loads up to 2 A, with a maximum module current of 12 A subject to rack and thermal limitations.

Supported electrical characteristics include:

• Rated output voltage: 115 VAC

• Operating voltage range: 85 to 135 VAC

• Frequency range: 47 to 63 Hz

• Maximum output current: 2 A per channel

• Maximum module current: 12 A

• Surge current: 20 A

Protection and Diagnostics

The module incorporates output-to-logic isolation rated at 1500 VAC. Integrated fuse protection helps protect the module and connected loads against fault conditions.

Front-panel LEDs provide individual output status indication, allowing quick verification of channel operating states during commissioning and maintenance.
