BCS过载保护板OP-97
OP-97适用于一个或多个变频器的电压输入信号的振幅监控；结构紧凑（145*123mm，可配控制箱-165*140*68mm，IP55等级）
技术参数：
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.
