Description

The IC693ALG390 is a high-performance analog output module designed for the General Electric Series 90-30 Programmable Logic Controller (PLC) system. This module provides two independent output channels capable of delivering precise voltage signals in the range of -10 to +10 VDC. It is engineered for demanding industrial environments, facilitating closed-loop control, signal transmission to measuring instruments, and integration with data logging systems.

Features

• Two isolated analog output channels (-10 to +10 VDC).
• High resolution of 2.5 mV per count.
• Absolute accuracy of ± 5 mV at 25 degC.
• 1500 VDC isolation between field wiring and PLC logic circuitry.
• Fast 5 ms update rate.
• Supports hold-last-state or 0V default configuration.
• External 24 VDC power supply input for standby operation.

Applications

This module is typically utilized in process control applications where precise voltage-based control is required, including:

• Closed-loop process control systems.
• Driving analog actuators and valves.
• Interfacing with chart recorders and data acquisition systems.
• Industrial automation test benches.

Technical Specifications

Installation Guidelines

• Power Down: Always disconnect power from the PLC rack before inserting or removing the module to prevent electrical damage.
• Mounting: Ensure the module is fully seated in the 90-30 baseplate slot and secured with the integrated locking screws.
• Wiring: Use shielded twisted-pair cabling for analog signals to minimize EMI interference. Ensure the shield is grounded at the source end only.
• Isolation: The module provides 1500V isolation; however, ensure external field wiring is routed away from high-voltage AC power lines.
• Environment: Maintain ambient operating temperatures between 0 and 60 degC. Ensure adequate ventilation within the enclosure.
