GE Fanuc IC697MDL251 AC Input Module | Series 90-70 Isolated Groups

IC697MDL251 Input Module

The IC697MDL251 is a 120 VAC input module from GE Fanuc. It belongs to the Series 90-70 product line. This module offers 16 input points in 4 isolated groups. Each group has 4 points and supports different AC phases. It works with limit switches, pushbuttons, and proximity sensors. The module draws 0.35 A from the 5 V backplane bus. A mechanical key prevents incorrect slot installation. The key can be removed and reinserted easily. Use wire sizes 14 to 22 for the terminal board. Turn off main power before removing the board.

Technical Specifications

Key Features & Compatibility

• Isolated Groups: 4 groups with 4 points each. Each group isolated for different AC phases.
• Wide Compatibility: Works with limit switches, selector switches, pushbuttons, and 2-wire/3-wire proximity sensors.
• Mechanical Keying: Prevents module insertion into wrong slot. Key is removable and reusable.
• LED Status: Individual LEDs show each input point status for quick diagnostics.
• Backplane Power: Requires only 0.35 A from the 5 V bus.
• Terminal Board: Removable field-wiring board accepts 14 to 22 AWG wires. Cable tie secures wire bundle.

Installation & Debugging

Insert the module into any Series 90-70 slot. The mechanical key ensures correct placement. To move the module, push the key upward to unhook it. Reinsert the key after choosing a new slot. Wire each input group to a separate AC phase. Connect the power source to the input terminals for all 4 groups. Use 14-22 AWG wire for the terminal board. Secure the wire bundle with the cable tie through the cleat. Always turn off main power before removing the terminal board. The module supports online monitoring via LED indicators.

Environmental & Certifications

• Temperature Range: 0°C to 60°C (operating)
• Humidity: 5% to 95% (non-condensing)
• Noise Immunity: High resistance to electrical interference
• Certifications: CE, UL, and RoHS compliant
• Diagnostic Capability: LED per input for real-time status
• Isolation: Group-to-group and group-to-backplane isolation

Typical Applications

• Discrete input monitoring in PLC systems
• Factory automation and conveyor control
• Packaging machinery input sensing
• Material handling equipment
• Process control with AC field devices

Diagnostic & Maintenance

Each input point has a dedicated LED. The LED shows the ON/OFF state of the input. This allows quick visual troubleshooting. The module does not require periodic calibration. Keep the terminal board clean and connections tight. Use the cable tie to manage wires and reduce strain. For obsolete system support, Oiltech Controls provides expert assistance.
