It samples line voltages and currents to calculate power quality parameters, harmonic distortion up to the 63rd order, and transient events. The meter routes alarm states to four relay outputs and transmits isolated analog signals and digital communication telemetry across rear RS485 and front RS232 ports.\u003c\/p\u003e\n\u003ch3\u003eHardware Specifications\u003c\/h3\u003e\n\u003cfigure class=\"table\"\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003e\u003cstrong\u003eParameter\u003c\/strong\u003e\u003c\/th\u003e\n\u003cth\u003e\u003cstrong\u003eSpecification\u003c\/strong\u003e\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel\u003c\/td\u003e\n\u003ctd\u003ePQM-T20-C-A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eGE Fanuc\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOrigin\u003c\/td\u003e\n\u003ctd\u003eUSA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e3kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003eStandard Panel Mount Form Factor\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temp\u003c\/td\u003e\n\u003ctd\u003e-20 to +60 deg C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Consumption\u003c\/td\u003e\n\u003ctd\u003e20 VA (20-60 VDC \/ 20-48 VAC, 50\/60 Hz)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAnalog Inputs\u003c\/td\u003e\n\u003ctd\u003e1 Channel (4-20 mA)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAnalog Outputs\u003c\/td\u003e\n\u003ctd\u003e4 Isolated Analog Outputs\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOutput Relays\u003c\/td\u003e\n\u003ctd\u003e4 Relay Outputs\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHarmonic Analysis\u003c\/td\u003e\n\u003ctd\u003eUp to 63rd Order\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCommunication Interfaces\u003c\/td\u003e\n\u003ctd\u003eRS485 (Rear Modbus), RS232 (Front)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003ch3\u003eChannel-to-Channel Isolation and Analog Loop Signal Processing\u003c\/h3\u003e\n\u003cp\u003eThe meter incorporates galvanic and channel-to-channel isolation across its four analog outputs to suppress ground loops and high-voltage common-mode noise. Internal analog front-end sampling converts incoming 4-20 mA transducer signals and voltage waveforms into digital registers for real-time Fourier transform calculations. Isolated signal conditioning circuits protect upstream DCS and PLC monitoring nodes against electrical transients originating on primary power buses.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: What power supply voltage range does the PQM-T20-C-A support?\u003c\/p\u003e\n\u003cp\u003eA: The device operates on low-voltage control power rated at 20-60 VDC or 20-48 VAC (50\/60 Hz).\u003c\/p\u003e\n\u003cp\u003eQ: How many relay outputs are available for local alarm tripping?\u003c\/p\u003e\n\u003cp\u003eA: The meter includes four programmable output relays for threshold alarms and automated control interlocks.\u003c\/p\u003e\n\u003cp\u003eQ: Which communication protocols and physical ports are integrated into the unit?\u003c\/p\u003e\n\u003cp\u003eA: The meter supports Modbus RTU communications via a rear RS485 port and direct local commissioning via a front-panel RS232 interface.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cp\u003ePrepare a standard square panel cutout on the enclosure door and slide the chassis into place from the front. Secure the mounting brackets onto the side panel channels and tighten screws evenly until the front bezel seal compresses firmly against the door panel. Route 4-20 mA analog output wires and RS485 communication pairs using shielded twisted-pair conductors, maintaining at least 200 mm clearance from unshielded high-voltage power lines. Connect the cable shield to the cabinet earth ground at a single point to prevent ground noise loops.\u003c\/p\u003e","brand":"GE FANUC","offers":[{"title":"Default Title","offer_id":52703014945080,"sku":"PQM-T20-C-A","price":220.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0893\/1616\/3896\/files\/PQM-T20-C-A2.jpg?v=1785226969","url":"https:\/\/www.automodulexpert.com\/products\/power-quality-meter-ge-fanuc-pqm-t20-c-a","provider":"AutoModuleXpert Ltd.","version":"1.0","type":"link"}
