Siemens 7NG4123 1AN00
Signal Isolator 7NG4123-1AN00 (7NG41231AN00) from the brand SIEMENS is from the NC range. The device provides fully floating dc supply for energizing 4 to 20 mA 2 wire transmitter or a separately powered transmitter with current or voltage outputs and repeats the signal in a fullyfloating circuit to drive a galvanic isolated load.However, Input configuration will be done by a rotary switch on the front plate. Configuration of output signal (current or voltage) will be made by jumpers on the backside. Installation must be in accordance to EN 60950. It must be possible to switch off the device using a suitable disconnecting device outside the power supply. (Primary side line protection could use).
