Description
Product Overview
The Honeywell 05701-A-0361 is a dedicated engineering card for the Honeywell System 57 rack platform. It serves as a local operator interface for commissioning, calibration, parameter setup and fault checking of System 57 control cards. This front-panel plug-in card enables technicians to perform zero/span calibration, alarm configuration, signal monitoring and event inhibit operations directly at the rack without external programming tools. Widely used in petrochemical plants and gas detection control systems, it is a legacy spare for maintenance and retrofit of existing System 57 installations.

Installation & Testing Notes
- Insert the engineering card into the dedicated slot on Honeywell System 57 rack
- Confirm backplane DC supply is within 18–32V DC before power-up
- Verify green power LED illuminates after energizing the rack
- Activate unlock mode (red LED ON) to modify calibration and alarm parameters
- Perform zero and span calibration against connected control modules and field transmitters
- This card does NOT support hot swap. Rack slot power must be isolated before removal
- After configuration, lock parameters and save settings; test alarm response for validation
