电流RS485串行通信模块
电流RS485通信模块（RS485）用于DNP3.0通信。模块有一个RS485通信端口。RS485是一种平衡的串行通信，可用于2线或4线连接。双线连接对RX和TX使用相同的信号，是一种多点通信，没有专用的主设备或从设备。然而，这种变体需要对输出进行控制。4线连接具有单独的信号，用于与专用主设备进行RX和TX多点通信，其余为从设备。在这种情况下，不需要特殊的控制信号。GPS时间同步模块GTM此模块包括用于时间同步的GPS接收器。GPS有一个SMA触点，用于连接天线。它还包括一个光学PPS ST连接器输出。IRIG-B时间同步模块IRIG-B-时间同步模块用于从站点时钟精确同步IED的时间。0XX和12X IRIG-B支架的电气（BNC）和光学连接（ST）。变压器输入模块TRM变压器输入模块用于电流分离和转换测量变压器产生的二次电流和电压。该模块有十二个不同电流和电压输入组合的输入。保护级或计量级CT输入可用。可以订购环形凸耳或压缩型替代连接器。高阻抗电阻单元单相单元和三相单元中都有高阻抗电阻装置，带有用于拾取值设置的电阻器和依赖电压的电阻器。两者都安装在带有压缩型端子的1/1 19英寸仪器板上

Galvanic RS485 serial communication module
The Galvanic RS485 communication module (RS485) is used for DNP3.0 communication. The module has one RS485 communication port. The RS485 is a balanced serial communication that can be used either in 2-wire or 4-wire connections. A 2-wire connection uses the same signal for RX and TX and is a multidrop communication with no dedicated Master or slave. This variant requires however a control of the output. The 4-wire connection has separated signals for RX and TX multidrop communication with a dedicated Master and the rest are slaves. No special control signal is needed in this case. GPS time synchronization module GTM This module includes a GPS receiver used for time synchronization. The GPS has one SMA contact for connection to an antenna. It also includes an optical PPS STconnector output. IRIG-B Time synchronizing module The IRIG-B time synchronizing module is used for accurate time synchronizing of the IED from a station clock. Electrical (BNC) and optical connection (ST) for 0XX and 12X IRIG-B support.Transformer input module TRM The transformer input module is used to galvanically separate and transform the secondary currents and voltages generated by the measuring transformers. The module has twelve inputs in different combinations of currents and voltage inputs. Either protection class or metering class CT inputs are available. Alternative connectors of Ring lug or Compression type can be ordered.High impedance resistor unit The high impedance resistor unit, with resistors for pick-up value setting and a voltage dependent resistor, is available in a single phase unit and a three phase unit. Both are mounted on a 1/1 19 inch apparatus plate with compression type terminals
Mounting alternatives
• 19” rack mounting kit • Wall mounting kit See ordering for details about available mounting alternatives. Injection equipment hardware Injection unit REX060 The injection unit REX060 is used to inject voltage and current signals to the generator or motor stator and rotor circuits. REX060 generates two square wave signals with different frequencies for injection into the stator and rotor circuits respectively. The response from the injected voltage and currents are then measured by the REX060 unit and amplified to a level suitable for the analog voltage inputs of IED. Stator injection module SIM The SIM module is installed into the REX060 enclosure. The SIM module generates a square wave voltage signal for injection into the stator circuit via the neutral point resistor or VT/DT. The SIM module measures the voltage and current from the injected signal and the IED consecutively calculates the stator to earth impedance. If the calculated impedance is lower than the preset value an ALARM and/or TRIP output is set. Rotor injection module RIM The RIM module is installed into the REX060 enclosure. The RIM module generates a square wave voltage signal for injection into the rotor circuit via a capacitor unit REX061 for isolation. The RIM module measures the voltage and current from the injected signal and the IED consecutively calculates the rotor to earth impedance. If the calculated impedance is lower than the preset value an ALARM and/or TRIP output is set. Coupling capacitor unit REX061 REX061 isolates the injection circuit from the rotor exciter voltage. The REX061 coupling capacitor unit grounding point and grounding brush of the rotor shaft should be properly interconnected. Shunt resistor unit REX062 REX062 is typically used when injection is done via a grounding transformer.
