Holt Company Insulated Discrete - Digital HI-8400
A robust solution for detecting OPEN/GND and 28V/OPEN discrete signals.
The HI-8400 is an isolated 4-channel discrete-digital sensor designed to output sensor data via SPI or a parallel bus interface. The isolation provides 800V of separation between each sensor and the logic interface, making it an ideal device for systems that need to accommodate various grounds. Each input can be individually pin-configured as GND/OPEN or 28V/OPEN. The discrete input thresholds comply with Airbus ABD0100H and MIL-STD-704 specifications. This device operates with a digital power supply of 3.3V (±5%) or 5.0V (±5%) for each isolated sensor and a 28V analog power supply. When GND/OPEN mode is selected on its pin, a 1mA wetting current is supplied from the input network of each SENSE input. The wetting current helps prevent dry relay or switch contacts. The sensor output interrupt pin alerts the system to changes in the sensor input, avoiding the need for regular polling via SPI to check the status.
