I/O modules

This I/O rack provides mechanical support and backplane connectivity for GE Series 90-70 modules. It holds up to five modules in a compact vertical arrangement. Therefore, this component suits small to mid-sized PLC configurations.

Physical Dimensions and Weight Specifications

The GE IC697CHS750 features a rugged steel construction for industrial environments. Its width accommodates five standard Series 90-70 slots. The rack depth reaches 185 mm for backplane mounting. Consequently, technicians can install this unit in shallow control cabinets.

Interface Types and Backplane Layout

The GE IC697CHS750 incorporates a passive backplane with five slot connectors. Each slot uses a 48-pin DIN connector for power and data. Two additional connectors at the rear handle rack-to-rack cabling. Hence, users can expand the system by linking multiple racks together.

Component Count and Structural Elements

This I/O rack contains one steel chassis with a corrosion-resistant coating. The chassis holds five backplane connectors soldered onto a multilayer PCB. You will also find five plastic guide rails for aligning inserted modules. An integrated grounding bus connects each slot to the protective earth terminal.

Energy Distribution and Current Capacity

The GE IC697CHS750 distributes 5V and 24V power across all five slots. Its backplane traces carry up to 20A total for the 5V rail. The 24V rail handles up to 10A for field electronics. Therefore, this rack supports mixed I/O and CPU configurations without external power distribution.

Installation Flexibility and System Expansion

Users can mount this rack vertically or horizontally per application needs. Four mounting tabs provide screw holes for panel attachment. A removable terminal block simplifies backplane power connections. This design reduces installation time for system integrators and maintenance staff.
