| Product information | The ACT20P-BRIDGE-S bridge measuring transducer converts measuring bridge voltages into standard signals. Buttons are used for adjustment to the measuring bridge connected. The bridge measuring transducer can supply up to 4 parallel-connected measuring bridges each with 350 Ω. The device supports simple compensation of the tare weight with a separate input for an external button or an external PLC signal. The power supply is electrogalvanised and isolated from the input and output (3-way isolation). Properties 4-wire and 6-wire measurement Supply of up to 4 parallel-connected measuring bridges each with 350 Ω Input and output ranges can be adjusted via DIP switches Tara compensation via external button or PLC signal Operating status display on a front panel LED Galvanic 3-way isolation between input, output and supply. |
