I/O modules

This input module acquires digital signals from field sensors for GE Series 90-70 PLCs. It transfers 120V AC signals to the CPU for logic processing. Therefore, this component suits limit switches, proximity sensors, and pushbutton applications.

Physical Dimensions and Weight Specifications

The GE IC697MDL250 occupies one standard slot in the Series 90-70 rack. Its housing measures 220 mm in depth for backplane connectivity. The module weighs approximately 0.48 kg for straightforward handling. Consequently, technicians can install this unit without additional rack reinforcement.

Interface Types and Connection Layout

The GE IC697MDL250 provides a 48-pin front connector for sensor wiring. A 20-pin backplane connector supplies power and data to the CPU. The front panel carries LED indicators for each active input channel. Hence, operators can monitor signal states at a quick glance.

Component Count and Channel Configuration

This input module contains one main board with 16 independent input channels. Each channel uses an optocoupler for electrical isolation from the field. You will also find a bridge rectifier for AC signal conversion. An onboard RC filter rejects noise from industrial environments.

Energy Storage and Power Consumption

The GE IC697MDL250 draws 120 mA from the 5V backplane supply. It also requires 10 mA per active channel from the AC field supply. A small capacitor bank filters noise on the AC input lines. This storage prevents false triggering from momentary power dips.

Signal Processing and Response Time

The module scans all 16 inputs within a 12 ms cycle time. It updates the CPU with fresh data after each scan completes. Users can connect this unit directly to standard AC switches. This direct connection reduces cabinet space and terminal block requirements.
