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 900G02-0102 with the target I/O slot and press firmly until the locking tab engages.
3. Terminal Block Wiring: Install the Euro style terminal block. Connect 24 VDC field wiring to the input and common terminals per group. Ensure cable insulation is rated for the installation temperature range.
4. Power On & Verification: Apply rack power and confirm the green blinking status LED indicates normal scanning. Verify each input channel LED responds correctly to field signals.
5. Configuration: Use ControlEdge Builder software to map channel addresses and configure state inversion if required.

Selection Tips

• Extended Temperature: Select the 900G02-0102 when the installation environment exceeds 60°C or drops below 0°C. For standard indoor environments, the 900G02-0202 (0°C to 60°C) offers equivalent functionality at standard specifications.
• Voltage Match: Verify all field devices operate at 24 VDC. This module does not support AC signals.
• Terminal Block: Order the compatible Euro style terminal block separately if not included in your system kit.
• Cable Selection: In sub-zero or high-heat environments, use industrial-grade cables with temperature ratings matching the -40°C to +70°C module specification.
• Redundancy: For critical outdoor or unconditioned installations, pair with redundant power supplies and the 900PSM-0101 Power Status Module.

FAQ

What is the difference between 900G02-0102 and 900G02-0202?

The primary difference is the operating temperature range. The 900G02-0102 is rated for -40°C to +70°C (extended temperature), while the 900G02-0202 is rated for 0°C to 60°C (standard temperature). Both share identical channel count, voltage rating, and electrical architecture.

Can this module be used in outdoor installations?

Yes, the extended temperature rating of -40°C to +70°C makes the 900G02-0102 suitable for outdoor enclosures, remote pump stations, and unconditioned industrial environments. Ensure the enclosure provides appropriate IP protection for the specific location.

Does this module support hot-swapping?

Yes. The ControlEdge HC900 platform supports Removal and Insertion Under Power (RIUP) for I/O modules. Follow proper ESD protocols and system documentation when performing hot-swaps.

What terminal block is required?

The module requires a Euro style terminal block. Confirm the exact part number with your Honeywell distributor.

Is this module compatible with third-party PLCs?

No. The 900G02-0102 is designed exclusively for the Honeywell ControlEdge HC900 rack architecture.
