Honeywell 900G02-0202 16-channel DC Digital Input Module Engineered

Honeywell 900G02-0202 ControlEdge HC900 24VDC 16-Channel Digital Input Module

The Honeywell 900G02-0202 is a 16-channel DC Digital Input Module engineered for the ControlEdge HC900 programmable logic controller family. It accepts 24 VDC field signals and is organized into two groups of 8 channels for streamlined wiring and diagnostics. Each channel includes a dedicated green LED indicator that illuminates when the input is in the ON state, while controller logic supports per-channel state inversion for flexible application programming.

Installation Guide

1. Power Down: De-energize the HC900 rack before module insertion unless performing a controlled hot-swap operation.
2. Module Insertion: Align the 900G02-0202 with the target I/O slot and press firmly until the locking tab engages.
3. Terminal Block Wiring: Install the Euro style terminal block onto the module front panel. Connect 24 VDC field wiring to the input terminals and common terminals per group. Use shielded cables in high-noise environments.
4. Power On & Verification: Apply rack power and confirm the green blinking status LED indicates normal scanning. Test each input channel to verify LED response and controller register mapping.
5. Configuration: Use ControlEdge Builder software to assign channel addresses and configure state inversion if required.

Selection Tips

• Voltage Match: Confirm all field devices operate at 24 VDC. This module does not support AC input signals.
• Temperature Range: The 900G02-0202 is rated for 0°C to 60°C. For installations in extended temperature environments (-40°C to +70°C), select the 900G02-0102 variant.
• Channel Density: For higher-density 24 VDC digital input requirements, consider the 900G32-0101 (32-channel) module.
• Terminal Block: Order the compatible Euro style terminal block separately if not included in your system kit.
• Power Budget: Verify the rack power supply capacity supports the total module load including all installed I/O cards.

FAQ

Can the 900G02-0202 accept AC input signals?

No. The 900G02-0202 is a DC-only digital input module designed for 24 VDC field devices. For AC digital inputs, use the 900G03-0001 (120/240VAC) module.

Does this module support hot-swapping?

Yes. The ControlEdge HC900 platform supports Removal and Insertion Under Power (RIUP) for I/O modules. Follow ESD precautions and consult system documentation before performing hot-swaps in active production systems.

What terminal block is required?

The module requires a Euro style terminal block. Confirm the exact part number with your Honeywell distributor, as terminal blocks are typically ordered separately.

How are the 16 channels organized?

The 16 inputs are arranged in two groups of 8 channels, each with dedicated common terminals for simplified field wiring.

Is this module compatible with third-party PLCs?

No. The 900G02-0202 is designed exclusively for the Honeywell ControlEdge HC900 rack architecture and communicates via the proprietary HC900 backplane.

Applications

• Discrete manufacturing and assembly line control
• Packaging machinery status monitoring
