The General Electric IC693ALG390G is a high-performance analog voltage output module designed for the Series 90-30 PLC platform. This module provides two independent output channels capable of delivering a voltage range of -10 to +10 VDC, making it suitable for precision control applications requiring bipolar analog signaling.

Features

• Two isolated analog output channels.
• Voltage output range of -10 to +10 VDC.
• Fast update rate of 5 ms for all channels.
• High resolution of 2.5 mV.
• 1500 Volts RMS isolation between the field and logic sides to ensure system integrity.
• Factory calibrated for consistent performance.

Technical Specifications

Installation Guidelines

• Ensure the PLC rack power is disconnected before installing or removing the module.
• The module must be seated firmly into the Series 90-30 backplane slot to ensure proper bus connection.
• Use shielded twisted-pair cabling for analog signal connections to minimize electromagnetic interference (EMI).
• Maintain proper grounding practices for the 24 VDC external power supply to prevent ground loops.
• Ensure adequate ventilation in the control cabinet to maintain operating temperatures within the specified 0 to 60 degC range.

FAQ

What is the primary function of the IC693ALG390G?

This module converts digital data from the Series 90-30 PLC processor into analog voltage signals (-10 to +10 VDC) for controlling external field devices such as actuators, valves, or variable frequency drives.

Does this module require an external power supply?

Yes, the module requires an external 18 to 30 VDC power supply to drive the analog outputs, drawing approximately 120 mA during operation.
