ISO-COMBO Card Pin Out

 

The ISO-COMBO Card uses not only the 8 Way onboard Green industrial connector but also has 19mm stand-off pin headers lifing the card off the main board to allow extra IO connectivity

The opto inputs use a TLP280GB opto isolator with 6K8 input resistors and can take AC/DC inputs between 5-40V. The connector also provides a 15mA 5V supply to allow external devices to be powered or to power relay contact inputs

The digital ouputs use signal relays 1A@24VDC with Normally Open contacts.

The ADC inputs are designed to read 4-20mA current loop sensors via 100R 0.1% resistor shunts
