GE IC697MDL653 – Series 90-70 32-Point 24VDC Discrete Input Module

In stock

Product Description:

The IC697MDL653 is a high-density digital input module for the GE Series 90-70 PLC. It provides 32 channels of 24VDC input, isolated into 4 groups (8 points each). It accepts -3V to +30VDC, supports positive/negative logic, and offers 1500VAC isolation. It is ideal for collecting on/off signals from switches, sensors, and pushbuttons.

Key Features:

High Density: 32 points in one slot reduce rack space, modules, and wiring.
Wide Voltage Tolerance: -3V to +30VDC handles 24V sensor fluctuations.
Group Isolation: 4 isolated groups prevent cross-talk; one group fault does not affect others.
High Dielectric Strength: 1500VAC isolation protects the PLC from voltage spikes.
Dual Logic Support: Works with sinking or sourcing sensors/switches.
Channel Diagnostics: Per-channel LEDs enable quick fault and wiring checks.
Industrial Hardening: Withstands vibration, shock, and wide temperature ranges.

Applications:

Factory Automation: Limit switches, photoeyes, and proximity sensors on production lines.
Process Control: Valve status, pump/run feedback, pressure, and level switches.
Building Infrastructure: Lighting, HVAC status, fire alarms, and elevator signals.
Safety Systems: E-stops, safety light curtains, and door interlocks.
