PRODUCT INFORMATION
Product Overview
The General Electric IC670MDL640J is a Field Control digital input module. This discrete module provides sixteen input points organized into a single electrical group. It operates with a rated voltage of 24 VDC across an operating range of 0 to 30 VDC. All sixteen input points share a common positive or negative logic configuration.
Each input circuit exhibits a typical input impedance of 3 kΩ. The unit draws a user input current of 7.5 mA per point at 24 VDC. User-to-logic optical isolation provides continuous protection up to 250 VAC. The backplane bus interface consumes 75 mA typical and 83 mA maximum with all inputs active.
