電流RS485串行通信模塊
電流RS485通信模塊（RS485）用于DNP3.0通信。模塊有一個RS485通信端口。RS485是一種平衡的串行通信，可用于2線或4線連接。雙線連接對RX和TX使用相同的信號，是一種多點通信，沒有專用的主設備或從設備。然而，這種變體需要對輸出進行控制。4線連接具有單獨的信號，用于與專用主設備進行RX和TX多點通信，其余為從設備。在這種情況下，不需要特殊的控制信號。GPS時間同步模塊GTM此模塊包括用于時間同步的GPS接收器。GPS有一個SMA觸點，用于連接天線。它還包括一個光學PPS ST連接器輸出。IRIG-B時間同步模塊IRIG-B-時間同步模塊用于從站點時鐘精確同步IED的時間。0XX和12X IRIG-B支架的電氣（BNC）和光學連接（ST）。變壓器輸入模塊TRM變壓器輸入模塊用于電流分離和轉換測量變壓器產生的二次電流和電壓。該模塊有十二個不同電流和電壓輸入組合的輸入。保護級或計量級CT輸入可用。可以訂購環形凸耳或壓縮型替代連接器。高阻抗電阻單元單相單元和三相單元中都有高阻抗電阻裝置，帶有用于拾取值設置的電阻器和依賴電壓的電阻器。兩者都安裝在帶有壓縮型端子的1/1 19英寸儀器板上

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.
