BCS過(guò)載保護(hù)板OP-97

OP-97適用于一個(gè)或多個(gè)變頻器的電壓輸入信號(hào)的振幅監(jiān)控；結(jié)構(gòu)緊湊（145*123mm，可配控制箱-165*140*68mm，IP55等級(jí)）

技術(shù)參數(shù)：

1）       - stabilized power supply unit, output voltage 10 V DC - 60 mA max., suitable to energize up to two 350 Ω load cells, parallel connected

2）       - load cells signal amplificator

3）       - input impedance: > 2 M W

4）       - accuracy: ± 0.1% of f.s.v., at nominal supply voltage, at 25 °C

5）       - temperature effect: ± 0.05%/°C from 0 to 50 °C

6）       - tare suppression and calibration by means of DIP switches and trimmers

7）       - two alarm SETs, for maximum load, with alarm values settable by means of trimmers.SPST output relays （1 NO and 1 NC）, 2 A at 110/220 V AC

8）       - "fail-safe" device, with activation of the alarm contacts in case of power and/or signal failure

9）       - supply voltage: 48 or 115 or 230 V ±10%, 50/60 cycle （to be stated）

10）   - consumption: dependant on configuration, 3 VA max.
