Function: KFD2-WAC2-Ex1.D-Y1

This isolated barrier is used for intrinsic safety applications.

The device is used with strain gauges, load cells and resistance measuring bridges.

Designed to provide 5 V excitation voltage, this barrier’s high quality A/D converter allows it to be used with those devices requiring 10 V.

Up to four 350 Ω strain gauges connected in parallel may be powered and evaluated.

The device is easily configured by the use of keypad or with the PACTware configuration software.

The current measurement for tare, zero point, and final value can be entered in this manner.

A fault is signalized by LEDs and a separate collective error message output.
