IC697BEM733 GE Replacement Power Circuit Boards PCB BEM 733 Remote I/O Scanner

The IC697 Remote I/O Scanner (IC697BEM733/735) is an intelligent module that mounts in a remote IC697 rack, and interfaces IC697 I/O modules to an IC66* bus. A Remote I/O Scanner and the modules it serves make up a remote drop on the IC66* bus. A remote drop can consist of up to eight racks, linked by Bus Transmitter and Bus Receiver modules. 9-slot and/or 5-slot IC697 racks can be used. The maximum distance from the first rack to the last rack in a remote drop is 50 feet (15 meters).

The Remote I/O Scanner can handle any mix of discrete and analog inputs and outputs up to a total of 1024 discrete inputs and 1024 discrete outputs, or 64 analog inputs and 64 analog outputs (regardless of the number of racks in the remote drop). A remote drop can include all presently-available IC697 discrete modules, analog modules, and analog expander modules. Bus Transmitter, Bus Receiver, PCM, and ADS modules can also be placed in a remote drop. A remote drop cannot have any I/O module interrupts, bus controllers, communications modules, or other modules that depend on COMREQ instructions for their operations.

The Remote I/O Scanner is ideally suited for use in an IC697 PLC system. However, any type of PLC or computer capable of controlling an IC66* bus can be used as the host. Suitable hosts include IC660 PLCs, IC655 PLCs, and computers equipped with a PCIM (Personal Computer Interface Module), QBIM (Q-Bus Interface Module), or a third-party GENI-based interface.
