Hi, Dear! Welcome to our online store...
XS-DI Digital input isolator
· 1 in 1 out, 1 in 2 out, 2 in 2 out. Suitable for contact switches, NAMUR proximity switches, OC signals or level signal inputs. Relay contact output, OC signal or level signal output. Line fault detection alarm function.
· The XS-DI digital input isolator is suitable for contact switches, NAMUR proximity switches, OC signals or level signal inputs. After isolation, it is transmitted to the control system or other instruments in relay contact output (or OC output, level output).
· Available in multiple channel styles (optional).
· Line fault detection function (optional).
· The product is powered by a separate DC power supply. Power-input-output and isolation between channels.
