Product:Honeywell 621-9937 PIOM DIP Switches New Original Guarantee 621-9937
Parallel I/ 0 racks are connected to the processor or other racks using PI OMs. The PIOM controls the 1/0 rack and communicates with the processor and other PI OMs. The 621-9937 replaces the 621-9930. The 621-9937 must be used in 1/0 racks that contain any combination of 32-, 16-, and 8-point I/0 modules. The PIOM has two 50-pin D type connectors. The male connector (top) is the IN port and the female connector (bottom) is the OUT port. A green LED labeled ACTIVE illuminates to indicate proper communication from a preceding rack. Each 1/0 rack accommodates one PIOM. Different I/0 racks within the same system may contain different PI OMs as long as the correct PIOM is used in each rack. Banks of DIP switches that set the rack configuration, output handling functions, and module configuration by point size, are located on the PIOM printed circuit board. Refer to the APPENDIX for PIOM DIP switch settings.
