GE IC697MDL653 | Series 90-70 32-Channel DC Input Module

Versatile Positive/Negative Logic Input Sensing

The IC697MDL653 provides thirty-two discrete input channels for the Series 90-70 platform from GE. This module accepts both positive and negative logic signals within a broad -3 to +30 VDC range. Furthermore, its flexible design accommodates various sensor types and wiring configurations in complex control systems.

Organized Group Architecture for Efficient Wiring

The module organizes its thirty-two channels into four independent groups of eight channels each. This grouping simplifies field wiring by allowing shared common connections within each group. Moreover, each group features 500 volts of isolation from other groups to prevent electrical interference.

Robust Electrical Isolation for System Protection

The IC697MDL653 provides 1500 volts of isolation between any input channel and the PLC backplane. This high level of protection safeguards the central processor from voltage transients and noise on field wiring. Consequently, it ensures reliable operation in electrically harsh industrial environments.

Wide Voltage Acceptance for Sensor Compatibility

The broad input range allows the module to interface with various 24VDC sensors and switches. It correctly interprets signals slightly below zero volts, which is crucial for certain negative logic applications. Therefore, the IC697MDL653 offers exceptional versatility for different electrical designs and legacy equipment.

Efficient Power Consumption from the Backplane

The module draws only 0.3 Amps from the 5VDC backplane, which is efficient for its channel density. This low power requirement allows for more modules to be installed in a single rack without exceeding power supply limits. This efficiency supports the creation of high-density I/O stations within the Series 90-70 system.

Ideal for Large-Scale Digital Input Applications

With thirty-two channels in a single module, it maximizes I/O density for cost-effective system design. Typical applications include large conveyor systems, material handling stations, and assembly lines with numerous sensors. System integrators select the IC697MDL653 for its channel count, isolation, and wiring flexibility.
