Part description

Product description
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.

Long specification

Bridge measuring transformer with electrical 3-way isolation, configurable
measurement isolating transformer in 22.5 mm width with external power supply, for recording,
transforming and isolating of measurements from industrial strain gauges.
Standard DC current/voltage signals are available on the output side. Measuring bridges of up to
3 x 350 Ohm can be supplied via the input circuit. Automatic tare calibration
via external switch signal, or manually with a press of a button.
6-wire connection compensates for differences in wire resistance. Bridge excitation voltage
can be switched between 5 v and 10 V. Load cells can be calibrated using a button on the front side.
I/O signals can be configured via DIP switches.
