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.
- Isolated loop-powered signal converter for common process signals - Field configurable inputs 4-20mA, 0-1mA, 0-10mA, 0-20mA, 0-1V, 0-2V, 0-5V, 1-5V & 0-10V. - 2-wire loop power or 3 wire output - 2000Vrms isolation. - Field configurable response time. - Front adjustments for span and zero.
