Description

The General Electric IC694MDL655 is a high-density discrete input module designed for the PACSystems RX3i control platform. This module provides 32 points of discrete input, organized into four isolated groups of eight inputs each. It is engineered to interface with a wide range of field devices, supporting both positive and negative logic configurations to ensure flexibility in industrial control applications.

Features

• 32 discrete input channels organized into 4 groups of 8.
• Supports both positive and negative logic input types.
• Wide input voltage range compatibility (0-30 VDC nominal, up to 60 VDC).
• Fast response time of 2 ms (maximum) for both On and Off transitions.
• Integrated LED status indicators for each channel to facilitate rapid diagnostics.
• Optical isolation between field side and backplane to protect control circuitry.

Technical Specifications

Installation Guidelines

• Ensure the PACSystems RX3i rack power is disconnected before installing or removing the module.
• The module must be seated firmly into the RX3i backplane slot and secured using the integrated locking mechanism.
• Use shielded cabling for field inputs to minimize EMI interference, especially in high-noise industrial environments.
• Maintain proper cable routing to prevent signal degradation and ensure compliance with maximum cable length specifications (30 meters).
• Handle the module using ESD-safe practices to prevent damage to sensitive internal electronic components.
