Strain Meter – 6 Digit Display With 3 Relay Outputs

OMEGA’s new panel meter for load cells delivers high-performance at 1/8 DIN size for panel mounts and integration in a wide range of weight applications. The DPS20 accepts 4 and 6 wire load cells and provides 5 Vdc and 10 Vdc configurable excitation voltage to power the load cell. Two power supply options for high and low AC/DC power, allows this unit to be suited for global use.

The optional relays, analog output, and Modbus® RTU serial communications provide control and communication capability. Additional features of the DPS20 load cell meter include independent scaling of the load cell signal and reading units, prevention of false tares, stability alarms, and rear terminal with configurable function.
