Description
GE 7VNDS143CD01
Technical Specifications
- Inputs: 16 isolated digital inputs (24VDC)
- Outputs: 16 SPST relay outputs (2A max)
- Isolation: 1500V channel-to-group isolation
- Response Time: <10 ms
Functional Features
- High Channel Density: 32 I/O points in a single module.
- LED Indicators: Individual status LEDs for each channel.
- Field Wiring: Removable terminal blocks for easy maintenance.
Application Scenarios
Machine control, conveyor systems, and building automation.
Performance Parameters
- Input Impedance: 3.3 kΩ.
- Relay Life: 10 million mechanical operations.
Material Composition
Industrial-grade relays and optocouplers with gold-plated contacts.
Structural Characteristics
Standard DIN-rail mountable module with push-in terminals.
Working Principle
Input circuits detect field voltage levels and report status to the controller. Output relays are energized by controller commands to switch external loads.
Installation Requirements
Wire inputs and outputs to separate terminal blocks. Provide snubber circuits for inductive loads.
Usage Precautions
Do not exceed relay contact ratings. Protect against voltage transients with proper suppression.
