I/O modules

The GE IC697MDL740 discrete output module drives field devices from a Series 90-70 system. This unit weighs 0.42 kg and measures 17.5 cm x 10.2 cm x 2.5 cm. It provides 16 discrete output channels on a single module. The module contains 16 power transistors and one logic interface IC. For energy storage, it includes one 220µF electrolytic capacitor. Therefore, the GE IC697MDL740 maintains output states during brief power interruptions.

Technical Specifications

The table below lists all verified parameters for the GE IC697MDL740. Use this data for your system integration planning.

Output Channel Features

Each of the 16 output channels uses a separate power transistor. The GE IC697MDL740 provides sourcing outputs with 12V to 24V DC operation. Consequently, you can drive solenoids, relays, and indicator lamps directly. Each channel delivers 0.5 A continuously without overheating. For inductive loads, the module includes internal flyback diodes.

Switching Performance

The turn-on and turn-off times reach just 1 millisecond each. Thus, this output module suits high-speed discrete control applications. The inrush current capability reaches 1.0 A for 10 milliseconds. Therefore, the GE IC697MDL740 handles lamp loads and capacitive devices reliably. The logic interface IC isolates the field outputs from the backplane.

Power and Energy Storage

The GE IC697MDL740 draws 150 mA from a 5V DC logic supply. Additionally, it requires field power from an external 24V DC source. Hence, the logic power consumption equals only 0.75W. The 220µF electrolytic capacitor provides 10 milliseconds of hold-up time. This short backup protects output states during minor voltage sags.

Installation and Connectivity

You can mount the GE IC697MDL740 into any Series 90-70 I/O slot. The module occupies one slot in the backplane. The 37-pin D-sub connector handles all 16 output wirings. For proper operation, use a dedicated 24V DC power supply for field devices. The GE IC697MDL740 works seamlessly with the RMS-TSG-TZ-C static trip unit.

Environmental Durability

This discrete output module operates reliably from 0°C to +60°C. It also withstands 95% relative humidity without condensation. The module survives vibration up to 2g from 10 to 150 Hz. Therefore, the GE IC697MDL740 suits most industrial control cabinets perfectly.
