Initially developed for industrial applications, the rugged IR-104 was conceived in the PC/104 format as a high-density I/O module for applications requiring isolation between the computer and its external switches. This versatile module features 20 optoisolated digital inputs boasting a 3V to 24V range AC or DC. The 20 relay outputs are housed on an easily detachable connector with a rating of 5A @ 250V AC and 30V DC.
This lightweight board features a compact 3.550” x 3.775” footprint while exceeding industry standards with a 0.492” maximum component height. With an impressive operating temperature range of –25 to +70 degrees Fahrenheit, this versatile relay board is easily adapted to any number of unique applications.
