High-Voltage Sensing Capabilities
The 900G02-0202 directly interfaces with 120V and 240V AC field circuits, eliminating the need for interposing relays or voltage converters. This simplifies cabinet wiring and reduces hardware costs.
Integrated Noise Filtering
Each input channel is equipped with hardware filtering to reject high-frequency electrical noise and contact bounce. This ensures the controller receives clean, stable signals, even in environments with heavy motor interference.
Compact 16-Channel Density
The module provides 16 independent inputs in a single rack slot, allowing engineers to handle high I/O counts within a small physical footprint. This high-density design maximizes the utility of the HC900 chassis.
Optical Isolation Protection
The module features robust optical isolation, protecting the sensitive controller electronics from high-voltage surges and ground faults that could occur on the field side, ensuring long-term system resilience.
Can I mix 120V and 240V signals on the same module?
Yes, the module supports both 120V and 240V signals, but it’s essential to follow the specific wiring group guidelines provided in the Honeywell HC900 installation manual to ensure proper isolation between different voltage sources.
Does this module support DC inputs?
No, the 900G02-0202 is designed specifically for AC voltage sensing. For DC applications (e.g., 24VDC), a dedicated DC input module like the 900G01 series is required.
How do I identify a channel failure?
The module features front-facing LED indicators for each of the 16 channels. These LEDs provide immediate visual feedback of the input status, allowing maintenance teams to verify field-side activity without the need for a laptop.
Is this product factory original?
Yes. The 900G02-0202 is 100% Brand New and ships in the original Honeywell packaging with factory-applied seals, ensuring it meets all technical and safety certifications.
