Communication and Interface Details
This module handles data exchange between the host CPU and remote I/O blocks. Therefore, it reduces wiring costs by replacing discrete point-to-point connections. The IC697BEM731U transmits at 153.6 Kbaud over shielded twisted pair cable. Meanwhile, the bus supports up to 30 devices across one segment for flexible layouts.
Physical Dimensions and Mounting
The unit occupies a single slot within a standard Series 90-70 rack. Its front panel measures roughly 150 mm by 100 mm by 40 mm. Furthermore, status LEDs on the faceplate simplify network troubleshooting in the field. The IC697BEM731U weighs about 0.9 kg, keeping rack loading predictable.
Power, Termination, and Environmental Notes
The module draws 5 VDC directly from the rack backplane power supply. It operates reliably between 0°C and 60°C in standard control cabinets. Additionally, proper bus termination prevents signal reflection and communication faults. Technicians should verify cable length and termination before commissioning any new segment.
