GE Fanuc IC697MDL253 Input Module | 24VAC 32-Point Series 90-70

GE Fanuc IC697MDL253 Input Module

The IC697MDL253 is a 32-point input module for the GE Series 90-70 PLC system. It operates on 24 VAC and divides inputs into 4 isolated groups of 8 points each. This design allows each group to use different AC supply phases. The module works with a wide range of input devices including proximity switches, limit switches, and selector switches.

Technical Specifications

Key Features & Capabilities

• Isolated Input Groups: 4 groups of 8 points support different AC phases for flexible wiring.
• Compatible with Proximity Switches: Works with 2-wire and 3-wire electronic proximity switches.
• Low Leakage Current: Only 2 mA off-state leakage minimizes false triggers.
• Fast Response: 20-microsecond input filter captures rapid signal changes.
• No DIP Switches: Software configuration via Windows NT, 95, or MS-DOS through SNP/TCP/IP.
• Mechanical Keying: Ensures accurate replacement and prevents incorrect insertion.

Installation & Compatibility

• Mounting: Plugs directly into Series 90-70 PLC backplane.
• Compatibility: Works with GE Series 90-70 CPUs and remote I/O systems.
• Input Devices: Supports limit switches, selector switches, and proximity sensors.
• Wiring: 3-wire proximity switches preferred for lower voltage drop and leakage.

Environmental & Certifications

• Temperature Range: Rated for standard industrial ambient conditions (0–60°C).
• Immunity: Resistant to electrical noise and transients common in factory floors.
• Certifications: Complies with GE Fanuc quality and safety standards for PLC I/O.
• Reliability: Solid-state design ensures long service life with minimal maintenance.

Diagnostics & Troubleshooting

• LED Status: Individual LEDs show ON/OFF state for each of the 32 inputs.
• Software Monitoring: Configuration software provides real-time input status and fault detection.
• Leakage Current Check: 2 mA off-state leakage allows easy verification of sensor health.

Typical Applications

• Discrete input monitoring for conveyor systems and material handling.
• Position sensing with proximity switches in packaging machinery.
• Limit switch and selector switch interfacing in automated assembly lines.
• Integration with remote I/O racks in distributed control architectures.

FAQ (Frequently Asked Questions)

• Q: Can I use 2-wire proximity switches?
  A: Yes, but 3-wire types are recommended for better performance.
• Q: What is the input current?
  A: 10 mA in the ON state; 2 mA leakage in the OFF state.
• Q: How do I configure the module?
  A: Use Windows NT/95 or MS-DOS software via SNP or TCP/IP.
• Q: Are the input groups isolated?
  A: Yes, 4 isolated groups of 8 points allow separate AC phases.
