Honeywell 900S75S-0460 I/O Scanner 2 Module
Overview
Honeywell 900S75S-0460 I/O Scanner 2 module is a remote I/O scanning module specifically designed for redundant control systems. It is deployed in a remote I/O rack and features two I/O connections: I/O A connects to CPU-A of the redundant controller rack, and I/O B connects to CPU-B.
The module is responsible for acquiring data from input modules and transmitting it to the main controller, while also receiving output commands from the main controller and distributing them to the corresponding output modules.
Function & Features
The 900S75S-0460 supports identification and control of the entire HC900 series I/O modules, including:
- Universal analog input and high-level analog input modules
- Multi-channel analog output modules
- Digital input/output modules (DC/AC/relay type)
- Pulse/frequency/quadrature encoder I/O modules
- Relay output modules, and others
900S75S-0460 Failsafe
Users can assign a failsafe value or state for each channel.
Trigger condition: Communication between the controller and the module is interrupted.
Safety application limitation: Applicable only for de-energize-to-safe scenarios.
If the control strategy does not call the I/O of a module, that module will not trigger diagnostics.
