DIGINQI
Isolated Quad Digital input Module

GENERAL DESCRIPTION
The DIGINQI is an electrically isolated, quad, input device that requires no external components for safe operation from 9V to 65V. The device has a complete microprocessor interface.

Isolation for the device is 2500Vrms for one minute which makes it ideal for applications with high transient voltages and different ground potentials.

The module comes in an encapsulated 40 pin DIP package. FEATURES

• Microprocessor Interface
• Single +5V Supply
• Operation from -40 °C to +85 °C
• UL and CSA Approval Pending

APPLICATIONS
• Relay Contact Readback
• High Noise Environments
• Ground Potential Variations
