Strain Gauge Converter
Opis
This signal conditioner provides the galvanic isolation between field circuits and control circuits. 1-channel signal conditioner, 24 V DC supply (Power Rail), Strain gauge input (full or half bridge), Output 0 mA .. ± 20 mA or 0 V .. ± 10 V, 2 relay contact outputs, Programmable high/low alarm, Configurable by PACTware or keypad, RS-485 interface, Line fault detection (LFD)pa. 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.
