IC694MDL260 | GE Fanuc | 120 VAC Discrete Input Module

Product Summary

The IC694MDL260 is a 120 VAC discrete input module for the PACSystems RX3i platform. It provides 32 input points organized in four isolated groups of eight points each. Isolation is implemented between groups, while inputs within each group share a common reference.

Core Specifications

• Model Number: IC694MDL260
• Module Type: 120 VAC Grouped Discrete Input Module
• Compatible System: PACSystems RX3i (requires CPU firmware version 3.50 or later)
• Number of Inputs: 32 (four isolated groups of 8 inputs)
• Rated Voltage: 120 VAC
• Input Voltage Range: 0 to 132 VAC, 47–63 Hz
• Input Current: 7.0 mA typical per point at rated voltage
• Backplane Current: 220 mA at 5 VDC (all inputs ON)

Electrical Characteristics

• On-State Voltage: 70 to 132 VAC
• Off-State Voltage: 0 to 20 VAC
• On-State Current: 5 mA minimum
• Off-State Current: 2.5 mA maximum
• Input Filter Time: Configurable from 20 ms to 2540 ms in 20 ms increments (set by CPU)
• Response Time: Dependent on filter setting (0–4 AC cycles)
• Isolation: 264 VAC continuous / 1500 VAC for 1 minute (field to backplane and group to group)

Hardware Integration & Diagnostics

• Status Indicators: 32 green LEDs (one per input) plus terminal block presence LED
• Terminal Block: Requires IC694TBB032, IC694TBB132, IC694TBS032 or IC694TBS132 (ordered separately)
• Diagnostics: Terminal block presence reported to RX3i CPU
• Hot Swap Capability: Supported in RX3i Universal Backplane

Installation Guide

1. Verify RX3i CPU firmware is version 3.50 or higher.
2. Power down the rack or use hot-swap procedure if supported.
3. Insert the module into any I/O slot, ensuring proper alignment with card guides.
4. Secure the module and install the appropriate terminal block.
5. Connect field wiring observing group commons.
6. Apply power and configure input filter times via the programming software.

Selection Guidelines

• Select IC694MDL260 for high-density 120 VAC applications requiring grouped isolation.
• For fully isolated 120 VAC inputs, consider IC694MDL250 (16 points).
• For 240 VAC requirements, refer to IC694MDL231.
• Ensure sufficient backplane power capacity for the 220 mA draw.
