Honeywell 900H03-0001 8-Channel AC Digital Output Module

Product Overview

The Honeywell 900H03-0001 is an 8-channel AC digital output module designed for the ControlEdge HC900 controller family. Featuring Triac outputs rated for 85–240 VAC, this module provides isolated, high-voltage switching for AC loads such as solenoid valves, contactor coils, indicator lamps, and motor starters. With individual channel isolation, built-in surge protection, and compact design, the 900H03-0001 is ideal for industrial automation applications requiring reliable AC load control.

FAQ

Installation Guide

1. Power Off: De-energize the HC900 rack before installing the 900H03-0001.
2. Slot Insertion: Insert the module into an available I/O slot and press firmly until the retention clips engage.
3. Field Wiring: Connect AC loads to the module terminals using appropriate high-voltage wiring (typically 14–18 AWG). Ensure proper torque on terminal screws.
4. Load Verification: Verify each load does not exceed 2 A continuous. For inductive loads, ensure the snubber circuit is adequate or add external protection if necessary.
5. Fusing: Install external fuses or circuit breakers for each channel to protect against overload conditions.
6. Status Check: Power on the rack and activate each output via the PLC program. Confirm the corresponding LED illuminates and the load operates correctly.

Selection Tips

• Choose the 900H03-0001 for 8-channel AC load switching with individual channel isolation.
• If you need more AC output channels, consider the 900H03-0202 (current revision) or add additional 900H03 modules.
• For DC output switching, use the 900H32-0302 (24 VDC, 32-channel) or 900H02-0102 (24 VDC, 16-channel).
• For relay outputs (isolated dry contacts), use the 900H01-0202 relay output module.
• Always install external fusing per channel to protect the Triac outputs from overload.
• Ensure total rack power budget accounts for the 218 mA @ 5 VDC module draw.
