Regulated current source SZP-73 datasheet

Product catalog summary
Overview: The SZP-73 is a regulated current source designed for industrial process control, capable of generating a user-settable current in the range of 4-20 mA. It features a local keyboard for adjusting output current and a display for showing current values within a range of -999 to 9999, with a selectable decimal point.
Specifications: The device supports a power supply range of 19V to 50V DC, 16V to 35V AC, or 85V to 260V AC/DC, with a maximum power consumption of 4.5 VA or 4.5 W. It includes a two-colored LED display with IP 40 protection, and an optional IP 65 LED display. The output is a passive 4-20 mA current with a 24V DC power supply output, stabilized at 100 mA. The device offers an accuracy of 0.1% at 25°C and stability of 50 ppm/°C.
Communication and Configuration: The SZP-73 features an RS-485 communication interface supporting Modbus RTU protocol, with data transmission rates from 1200 to 115200 bit/s. Configuration can be done via the local keyboard or using the free S-Config software through the RS-485 port.
Environmental Conditions: The operating temperature range is 0°C to +50°C, with an optional range of -20°C to +50°C. Storage temperature ranges from -10°C to +70°C, depending on the option selected. The device is housed in a NORYL case with dimensions of 72 x 36 x 97 mm and a panel cut-out size of 66.5 x 32.5 mm.
Software and Accessories: SimCorder Soft is available for data visualization, reporting, and archiving, with features for emergency notifications via SMS or email. The SRS-U4 module allows USB connection to RS-485 devices, providing galvanic isolation. Various mounting brackets and adaptors are available for different board thicknesses.

Regulated current source SZP-73 datasheet-1

Regulated current sources 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 "A" 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. TECHNICAL DATA SIMEX Ltd., Wielopole 11, 80-556 Gdansk, Poland, tel.
