The Honeywell 900G03-0001 is a high-voltage digital input module purpose-built for the Honeywell HC900 process control system. This unit monitors AC-powered equipment status through sixteen isolated input channels. It accepts standard 120 VAC or 240 VAC line voltages directly without external signal conditioners.

Key Technical Specifications

Direct 120/240 VAC Input Capability

The 900G03-0001 accepts standard AC line voltages without intermediate relays or converters. You therefore connect motor starters, valve position switches, and pump run signals directly to the HC900 system. This direct interface eliminates interposing hardware and simplifies panel design. Consequently, you reduce both component costs and installation labor.

Sixteen Channels in Two Isolated Groups

This module organizes its sixteen inputs into two isolated banks of eight channels each. Each group withstands 350 VAC galvanic isolation from the other and from system logic. You therefore mix different voltage sources within the same module safely. One group can monitor 120 VAC circuits while the other handles 240 VAC equipment.

Purpose-Built for Honeywell HC900 Systems

Honeywell engineered the 900G03-0001 exclusively for the HC900 process control platform. You install this module directly into the HC900 rack without additional adapters. The system automatically recognizes the module and configures default parameters. Integration requires no special drivers or custom function blocks.

Robust Environmental Specifications

This module operates continuously from -20 °C to +70 °C ambient temperature. You therefore install it in non-conditioned electrical rooms and outdoor enclosures. Non-condensing humidity tolerance reaches 95 percent. The 900G03-0001 delivers reliable service in harsh industrial environments.

Mechanical Dimensions and Mounting

The module measures 130 mm in height, 45 mm in width, and 115 mm in depth. You mount it in any standard HC900 I/O rack slot. Its 0.45 kilogram weight ensures secure retention under vibration. Removable terminal blocks accept 12 to 22 AWG field wiring.

Input Circuit Protection

Each channel includes internal current-limiting and transient suppression. You therefore connect field wiring without external fusing or surge protection. The 900G03-0001 withstands continuous overvoltage up to 300 VAC without damage. This robustness simplifies troubleshooting and reduces spare parts inventory.

LED Status Indication

Sixteen individual green LEDs indicate the energized state of each input channel. You verify field device status immediately without a connected programming terminal. Additionally, a module status LED confirms proper communication with the HC900 controller. This visual feedback accelerates commissioning and troubleshooting.

Energy Storage and Maintenance

The 900G03-0001 contains no internal batteries or supercapacitors. You therefore eliminate periodic replacement maintenance. All configuration parameters reside in non-volatile memory within the HC900 controller. Module replacement requires no recalibration or special tools.
