The mini USB 4 channels relay output / photo isolator input
card provides photo coupler digital input and relay output
channels. The photo isolator input part provides 4 photo
coupler digital input channels, which allows the input signals to
be completely floated and prevent the ground loop. The relay
output part provides 4 relays to drive 4 different output
channels. Each relay channel can be used to control ON/OFF
of external devices, to drive external power relays, to activate
alarms... etc.
The mini USB 4 channels relay output / photo isolator input
card provides Plug and Play (PnP) features, it is a
programmable I/O interface card for PC/486, Pentium, or
compatibles. The on board Cortex™-M0 core provides USB
2.0 full-speed functions running up to 50 MHz and features
64K bytes flash, 8K bytes embedded SRAM and 4 Kbytes
loader ROM for the ISP.
 The features of mini USB 4 channels relay output /
photo isolator input card are:
 USB2.0 with Plug and Play (PnP) features.
 High speed Cortex™-M0 core.
 Support USB ID selection to identify USB device.
 Power supplied from external DC +5V/1A.
 Support 4 photo couple input channels and 4 relay
output channels.
 Allow the photo input signals to be completely floated
and prevent the ground loops.

5000V/1 minute, current transfer ratio is 300 to 600%,
collector-emitter voltage is 60V, emitter-collector
voltage is 6V, collector current is 50 mA, and
maximum load voltage is 30V.
 Activation voltage of photo input:
When short jumpers (input range from 0 to 20V DC)
0 to 4.5V inactive
6 to 20V
When open jumpers (input range from 0 to 30V DC)
0 to 16.5V inactive
18 to 30V
