Strain gauge input module with basic functions

Category: SKU: 5NIZSG

NI20SG is a strain gauge signal converter. Measurements taken using the 6-wires or 4-wires technique are available through Modbus-RTU serial protocol or the analog output. Sensitivity from 1 to 64mV/V, settable by DIP-switch for integer values, via software for real/integer values by connecting to the device via the microUSB port on the front panel. Stable weight indication via Modbus register/digital output. Remote writing of the tare in volatile and/or non-volatile memory by digital input/Modbus register/Modbus commands. Z-PC-DINAL2-17.5, Z-PC-DIN2-17.5, and Z-PC-DIN8-17.5 are mandatory accessories for ModBUS configurations.
