Description

Interface module with 4 analog input channels configurable for 10V and 20mA. Each channel can be configured indipendently form others to measure a 10V voltage or a 20mA current.
The inputs have a resolution of 12bits and particularly low response times.
Easy integration in the “PLC Configuration” of CoDeSys tool in conjunction with the compact Web PLCs.
Ultra compact (only 17.5mm wide) realization with DIN rail mounting.
