Isolation and 1:1 Conversion of Current Signals 1 Current Input—1 Current Output Slimline Housing—Only 6 mm (0.24") Wide Fast Response Time <7 ms High Accuracy, <0.05% of Span Easy-to-Use—No Setup Needed
产品描述 The DRSL-DC1 isolated repeater provides a competitive choice in terms of both price and technology for galvanic isolation of current signals to SCADA systems or PLC equipment. The unit provides isolation and 1:1 conversion of standard current signals. The unit offers isolation between input, output and supply. Provides surge suppression and protects control systems from transients and noise. The DRSL-DC1 also eliminates ground loops and can be used for measuring floating signals. Low power consumption facilitates DIN rail mounting without the need for any air gap. Measurement ranges are factory calibrated. The unit operates over a wide temperature range from -25 to 70°C (-13 to 158°F).
