4x DO, electromagnetic relay isolation. contact rating: 1A 30V DC/0.5A, 125V AC/0.3A, 60V DC. Connector: green terminal bond with pitch of 3.81mm


4x DI, photo coupler isolation, green terminal bond with pitch of 3.81mm, it's configured as direct current voltage input, voltage from 3V to 24V set to be high level and voltage below 1V DC set to be low level, it also could be set as internal isolated 5V power input and external dry contact


Standard DVI-I connector, Topway brand LMT070DICFWD-AKA LCD is supported by default

Power Failure Protection

CPU is with 1x GPIO for external power supply mode detecting, when external power input voltage is above 8V, IO will be high level, and PG green LED on case is lighting; otherwise IO will be low level and PG green LED will be light off.

When external power input cut off, system will be automatically switch to get power supply from supercapacitors and the PG red LED will be lighting, the supercapactiors could supply power at least 15 seconds and detect whole unit internal 5V main power voltage. When voltage falls more than 10%, the whole device will be cut off to avoid system failure because of overlow voltage
