The UT-5512 is an 8-channel relay output controller with an external RS-232/485 opto-isolated communication interface. It is very easy to use the program to control the functions of those outputs, plus simple drive lines to drive external devices (e. g.: pneumatic components, external relay switches, electric eye status, remote control interface instruments, analog-to-digital-to-analog converters, stepper motor control, etc. ).
