SI231 Signal Isolator


The SI231 is a loop powered transmitter that combines signal isolation and conversion in one compact package. The SI231 is ideal for in field enclosures or as a space saver in larger control cabinets. The base unit features link select-ability for standard process inputs. No special tools or components are required for range changing in the field. Reverse or direct-action mode is easily changed by solder pads on the base board. Standard output is 4 - 20mA with a wide supply range of 7.5 to 40Vdc.
