I/O modules

This bus transmitter module extends I/O communication for GE Series 90-70 systems. It transmits data between the main rack and remote I/O stations. Therefore, this component enables distributed control architectures for large facilities.

Physical Dimensions and Weight Specifications

The GE IC697BEM713 occupies one standard slot in the Series 90-70 rack. Its housing measures 220 mm in depth for backplane connectivity. The module weighs approximately 0.46 kg for straightforward handling. Consequently, technicians can install this unit without additional rack reinforcement.

Interface Types and Connection Layout

The GE IC697BEM713 provides two RS-485 ports for bus cabling. A 20-pin backplane connector supplies power and data from the CPU. The front panel carries LED indicators for bus status and diagnostics. Hence, operators can monitor network health at a quick glance.

Component Count and Communication Protocol

This bus transmitter module contains one main board with a dedicated protocol processor. The board holds 32 KB of buffer memory for message queuing. You will also find line driver circuits for the RS-485 ports. An onboard oscillator generates the bus clock signal.

Energy Storage and Power Consumption

The GE IC697BEM713 draws 250 mA from the 5V backplane supply. A small electrolytic capacitor maintains buffer memory for 10 milliseconds. This short storage protects message data during brief power dips. The module does not require a backup battery for normal operation.

Network Performance and Diagnostics

The transmitter supports up to 32 remote stations on a single bus segment. It automatically detects cable breaks and reports errors to the CPU. Users can read diagnostic status via the programming software. This feature reduces troubleshooting time for remote I/O faults.
