The iReact-TAP-3 unit is a smart sensor, providing position information of the substation’s transformer On-Load Tap Changer (OLTC). It is suitable for direct interconnection with the iReact automation controllers. The iReact-TAP-3 provides a pot-position transducer that converts input potentiometer position to 4…20mA analog output signals. In addition, the device provides 20 digital outputs that indicate the current position of the OLTC. The sensor is able to digitally configure and independently calibrate the two analog outputs, using a host computer interfaced via USB. The iReact-TAP-3 has built-in power supply, supporting 36-115VDC power input.
