Description

The IC693MAR590 is a combination input/output module designed for the GE Fanuc Series 90-30 PLC platform. This module integrates 8 AC input channels and 8 relay output channels into a single compact assembly. It is engineered for demanding automated environments, including power generation, mining, and oil and gas processing, where it facilitates the control of field devices such as motor contactors, valves, and control switches. The module provides 1500 V RMS electrical isolation between field circuits and internal logic to minimize noise interference and enhance system reliability.

Features

• 8 AC input channels with optical isolation.
• 8 mechanical relay output channels for versatile load switching.
• 1500 V RMS isolation between field and logic circuits.
• Supports a wide range of AC input voltages (0 to 132 VAC).
• Compatible with both DC and AC field loads on the relay outputs.

Applications

This module is suitable for discrete control applications in industrial automation systems, specifically where mixed signal types are required in a single rack slot. It is commonly used for interfacing with high-current field devices that require physical contact isolation.

Technical Specifications

Installation Guidelines

• Ensure the PLC rack is powered down before inserting or removing the module to prevent electrical damage.
• Verify that the module is fully seated in the backplane connector and secured with the integrated locking mechanism.
• Use appropriate shielded cabling for field inputs to reduce EMI/RFI noise in high-interference environments.
• Ensure that the relay output load does not exceed the maximum current rating (2A) or inrush current limits (5A) to prevent contact degradation.
• Maintain adequate airflow within the cabinet to ensure the module operates within the 0 to 60 deg C temperature range.

FAQ
