Description

The IC695ALG808 is a high-density, isolated analog output module designed for the GE Fanuc Emerson PACSystem RX3i platform. This module provides eight independent channels capable of delivering precise voltage or current signals to field devices, including actuators, variable frequency drives, and control valves. Engineered for demanding industrial applications, it features a high-speed backplane interface and robust 2550 VDC isolation between field circuitry and the backplane to prevent ground loops and protect the controller from electrical surges.

Features

• Eight independent, isolated analog output channels.
• Supports multiple output ranges: 0 to +10 V, -10 to +10 V, 0-20 mA, and 4-20 mA.
• High-fidelity resolution: 14-bit for bipolar voltage and 15-bit for unipolar voltage and current.
• Fast 8 ms update rate across all channels with a 2 ms settling time.
• Supports both IEEE 32-bit floating point and 16-bit integer data formats.
• Requires external 24 VDC power supply for output circuitry.

Applications

This module is suitable for mission-critical control loops in industries such as oil and gas, power generation, and mining. It is ideal for driving proportional control valves, positioners, and remote instrumentation where signal isolation and high precision are required.

Installation Guidelines

• Ensure the RX3i backplane is powered down before inserting or removing the module to prevent electrical damage.
• The module must be installed in a standard RX3i rack slot; ensure the module is fully seated and the locking levers are engaged.
• Use shielded twisted-pair cabling for all analog signals to minimize EMI/RFI interference.
• Ground the cable shields at the source or the module end according to your specific system grounding plan to maintain signal integrity.
• Maintain adequate clearance around the module for proper ventilation to manage the 7.25 W maximum power dissipation.
• Verify that the external 24 VDC power supply is within the 19.2 V to 30 V range before connecting to the terminal block.

FAQ

Does this module support HART communication?

No, the IC695ALG808 is a standard isolated analog output module and does not support HART protocol communication.

Is an external power supply mandatory?

Yes, an external 24 VDC power supply is required to energize the output circuitry of the module. The backplane power is used for internal logic and communication only.
