GE IC693MDL645J Input Module

The GE IC693MDL645J acquires signals from AC switches, sensors, and limit switches. This input module measures 125 mm in height and 25 mm in width. It fits standard Series 90-30 rack slots without any modifications. The unit weighs 0.23 kg, making installation quick and straightforward.

Channel Configuration and Input Specifications

This input module provides 16 independent input channels on its front panel. The GE IC693MDL645J accepts 120V AC signals from industrial field devices. Each channel draws 12 mA at 120V AC for reliable signal detection. The module includes optocoupler isolation between field and logic circuits. Input response time ranges from 10 ms to 30 ms for noise rejection.

Voltage Thresholds and Operating Range

The module detects an on state when voltage exceeds 74V AC. The GE IC693MDL645J recognizes an off state when voltage falls below 20V AC. The nominal input voltage rating is 120V AC at 50 or 60 Hz. Each channel tolerates continuous overvoltage up to 132V AC safely. Input impedance measures approximately 10,000 ohms for each channel.

Internal Architecture and Component Layout

The module contains two separate circuit boards inside its plastic housing. One board handles input filtering, while the other manages backplane communication. The GE IC693MDL645J includes 16 LED indicators for individual channel status. A 48-pin edge connector interfaces with the Series 90-30 backplane. The module stores 47 µF of capacitance for power supply filtering only.

Power Requirements and Environmental Tolerance

The GE IC693MDL645J draws 120 mA at 5V DC from the backplane supply. It requires no external 24V DC power for its input circuits. The module operates reliably from 0°C to 60°C ambient temperature. It tolerates humidity levels up to 95 percent without any condensation issues. The unit withstands vibration up to 2g from 10 to 500 Hz.
