Product Overview
Honeywell 900H03-0202 is a Digital Output Module for 120/240 VAC systems. It provides 8 isolated zero-switching Triac outputs. Each channel has a green LED for ON state. A blinking green status LED shows module scanning. A red status LED shows diagnostics. The module uses MOV protection and a field-replaceable fuse per output. A shorting comb (900J02-0001 or 900J10-0001) helps connect all outputs to a common voltage source. This module fits barrier-type terminal blocks. It supports fail-safe state configuration: Hold Last State or Failsafe State. The design suits industrial automation panels that need reliable AC switching with clear diagnostics.

Diagnostics and Maintenance
- Green LED per channel shows output ON state.
- Blinking green status LED shows module scanning.
- Red status LED shows module diagnostics exist.
- Field-replaceable fuse per output simplifies repair.
- MOV transient protection reduces overvoltage risk.
- Fail-safe configuration supports safe shutdown design.
Installation and Compatibility Notes
Use barrier-type terminal blocks with the optional shorting comb 900J02-0001 or 900J10-0001. The comb ties all outputs to a common voltage source. Keep wiring short and use proper AC fusing. The module works with Honeywell 900H series backplane systems. It suits resistive loads within the specified current range. Verify load current stays above 50 mA minimum and below 2 A per point.
