GE IC693BEM331M Series 90-30 Genius Bus Controller (Revision M)

Communication protocol is GE Genius I/O Bus. Baud rates are configurable at 19.2 kbps, 38.4 kbps, 76.8 kbps, and 153.6 kbps. Maximum node count is 64 Genius blocks. Multi-master support allows distributed control architectures. Global data exchange enables shared memory between devices. Backplane power consumption is approximately 2.5 W at 5 VDC.

Revision M represents a later hardware revision with updated component obsolescence management and reliability improvements. Full support for high-speed 153.6 kbps operation. Multi-master capability and global data exchange are maintained. Compatible with all existing Genius I/O blocks and network configurations.

New installations requiring the latest revision hardware, replacement of older Genius bus controllers, and expansion of existing Series 90-30 distributed I/O networks.

153.6 kbps maximum baud rate delivers deterministic high-speed communication. 64-node network capacity supports extensive I/O distribution. Low backplane power consumption leaves capacity for additional modules.

Industrial housing with revision M specified components, protocol processor, and isolated communication circuitry.

Standard Series 90-30 single-slot module. Genius bus connector and LED indicators match base model configuration.

Operates as a Genius bus master controller, executing token-passing protocol management, remote I/O scanning, and global data broadcasting across the Genius network.

Install in Series 90-30 baseplate. Configure network address and baud rate. Connect shielded twisted-pair cable with proper termination. Verify revision M compatibility with system firmware.

Verify all network devices support the selected baud rate. Maintain single-point shield grounding. Replace older revision modules with revision M using identical configuration parameters. Monitor LED indicators for communication faults.
