Product:Honeywell 620-1633 620 Logic Controller System New Original Guarantee

The interface printed circuit board contains the logic circuitry necessary to interface the processor to the rack 1/0 bus and the option cards. A bank of eight DIP switches enables or disables several functions including: FORCE, battery low start-up inhibit, on-line programming and data change functions. The DIP switch settings determine whether the processor will recognize or ignore processor rack output card faults. Clearing or freezing outputs at recognized card faults is also set at the Interface Board SWl. Refer to the APPENDIX for a complete listing of the Processor Module DIP switches and their functions.
