Key Features and System Integration
This module connects directly to field devices like push buttons, limit switches, and relays. Its dual isolated input groups help prevent ground loop issues in complex systems. Each of the sixteen channels features a dedicated green LED for visual ON/OFF status. Moreover, the module supports logic state inversion through the host controller software. This provides application flexibility for both normally-open and normally-closed devices.
Application Context and Operational Reliability
The 900G02-0001 is ideal for monitoring discrete events in industrial automation. It reliably interfaces with safety interlocks, position sensors, and motor run feedback signals. The module’s wide operating voltage range accommodates typical 12V and 24V DC control circuits. Its fast 4ms response time ensures timely detection of state changes. Therefore, it is a dependable component for machine control, process sequencing, and status monitoring.
Installation and Configuration Notes
Install the module in a compatible Honeywell 900 Series I/O rack or baseplate. Field wiring connects to the module’s terminal blocks according to the grouping scheme. The 900G02-0001 does not supply power to the field devices; it requires an external source. Configuration of inversion logic and filtering occurs within the system’s control programming software.
