Honeywell 900H02-0102 Digital Output Module Overview

The Honeywell 900H02-0102 is a high-density DC digital output module. It belongs to the Honeywell 900 Series I/O family. This module provides 16 discrete outputs for industrial control applications. Each output uses low-side switching (current sinking) technology. The 900H02-0102 offers reliable performance for PLC and DCS systems.

Technical Specifications

Output Characteristics

The 900H02-0102 includes 16 current-sinking outputs per module. These outputs split into two groups of 8 channels each. Each group has separate +V and COM screw terminals. The operating voltage ranges from 6.5 to 32 VDC. Between 5.0 and 6.5 VDC, current stays below 0.5A per channel. Maximum peak voltage reaches 34 VDC.

This module uses an intelligent power switch (IPS) output type. The ON voltage drop measures only 0.3 VDC at 1A load. Maximum load current is 1A per point or 8A total per module for resistive loads. For incandescent lamp loads, use 0.5A per point with 5 mH maximum inductance. Maximum leakage current stays at 0.15mA @ 32 VDC. The minimum load is 0.0 mA for flexible operation.

Response Times and Protection

The 900H02-0102 delivers fast switching performance. OFF to ON response time is 6 ms. ON to OFF response time is also 6 ms. Maximum inrush current reaches 4A for 10 ms. Each output includes built-in electronic overload protection. The protection uses high current and high temperature limiting. When tripped, you must recycle field power to reset the module.

Isolation and Power Requirements

The 900H02-0102 provides galvanic isolation across two output groups. This design prevents cross-group interference. The module draws 340mA from the 5V power supply. The 24V power supply draws 0mA for efficient operation. AC frequency is not applicable for this DC module.

LED Status Indicators

The 900H02-0102 features a green LED for each output channel. This LED lights when the digital output is ON. A green blinking status LED shows the module is being scanned. An amber blinking status LED indicates forced channels. A red status LED alerts you to module diagnostics.

Installation Guidelines

Always disconnect field power before installing the 900H02-0102. Mount the module securely in your Honeywell 900 Series rack. Connect external DC power to the +V and COM screw terminals for each group. Wire each output channel to your field devices. Use appropriate wire gauges for 1A maximum current. After wiring, apply 6.5 to 32 VDC power to the module. The green status LED will blink to confirm scanning. If an overload trips, cycle field power to reset the 900H02-0102.
