Code: SZP-73
  • regulated current source in a small case
  • two-coloured LED display (4-digits, IP 40)
  • passive output 4-20 mA with galvanic separation
  • power supply output: 24V DC
  • RS-485 / Modbus RTU
  • changing the current values by "^" and "v" keys
  • free configuration software S-Config

Regulated current source SZP-73 allows generation of user settable current (in range 4...20 mA). Increasing and decreasing of output current can be made using local keyboard. Device displays present value of output current recalculated according to set display range (-999 to 9999 with free selectable decimal point). Quick view and regulation of output current is possible at any time. The device can replace all two wire analogue current sources (4...20 mA) used for controlling of industrial processes. The 24V DC / 100 mA output is designed to supply measuring transducers, and the RS-485 port enables data transmission in production process monitoring systems. The meter can be configured with the local keyboard or free S-Config software via the RS-485 communication port.
