Honeywell- dr-4500 chart recorder- isolated input board
Honeywell - DR-4500 Series, Chart Recorder / Controller - Isolated Input Option Board Assy. No.30754913-001. This is an Isolated Input Option Board pulled from a working unit, no longer using this Input. It comes as pictured with the connectors, and is designed to be mounted off the processor board with an edge connector. A steal compared to new from Honeywell.
