GE IC697CHS750C – PLC Rack for Series 90-70 I/O Modules

The GE IC697CHS750C provides mechanical housing and backplane for up to 10 I/O modules. This PLC rack measures 480 mm in width and 280 mm in height. It has a depth of 200 mm, so it fits standard 19-inch cabinets easily. The unit weighs 4.5 kg, making rack mounting secure and stable.

Slot Configuration and Backplane Architecture

This rack provides 10 slots arranged in a single horizontal row. The GE IC697CHS750C includes an active backplane with bus termination circuits. Each slot accepts any standard Series 90-70 module type. The backplane supports both 5V and 24V power distribution to modules. A built-in power supply slot accepts the main rack power supply unit.

Backplane Communication and Data Transfer

The active backplane uses a parallel bus for high-speed data exchange. The GE IC697CHS750C achieves transfer rates of 2.5 Mbit/s between modules. The backplane includes automatic bus arbitration for multiple module access. A 48-pin edge connector in each slot interfaces with inserted modules. The rack supports both single and dual-bus configurations for redundancy.

Internal Components and Power Distribution

The rack contains one backplane PCB with all bus traces and connectors. The GE IC697CHS750C includes termination resistors for signal integrity. A power distribution PCB routes voltages to each module slot individually. The unit stores 330 µF of capacitance for bus voltage filtering. LED indicators show +5V and +24V bus voltage status.

Environmental Specifications and Mounting Options

You can mount this rack horizontally in any standard 19-inch cabinet. The device operates reliably from 0°C to 55°C ambient temperature. It tolerates humidity levels up to 95 percent without any condensation issues. The GE IC697CHS750C includes grounding studs for proper electrical safety. Ventilation slots allow passive convection cooling of inserted modules.

Below is a complete summary of its technical specifications.

The GE IC697CHS750C replaces older rack assemblies in Series 90-70 systems. You do not need any special adapters or additional mounting hardware. This rack also supports hot-swapping of most I/O modules during operation. Consequently, it provides a reliable backplane for large PLC configurations.
