Manufactured by Horner APG, this module provides high-precision temperature monitoring by allowing direct connection of J and K type thermocouples to the PLC backplane, eliminating the need for external signal conditioners or transmitters. With an 18-bit integrating A\/D converter and a resolution of 0.1 degC, it is engineered for demanding industrial temperature sensing applications.\u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e8 isolated input channels for J and K type thermocouples\u003c\/li\u003e\n\u003cli\u003eHigh-resolution 18-bit A\/D conversion with 0.1 degC precision\u003c\/li\u003e\n\u003cli\u003eIntegrated cold junction compensation via terminal block temperature sensing\u003c\/li\u003e\n\u003cli\u003eOpen-circuit detection with dedicated alarm bits for each channel\u003c\/li\u003e\n\u003cli\u003eFast data acquisition with a scan rate of up to 40 channels per second\u003c\/li\u003e\n\u003cli\u003eDirect backplane power consumption of 100mA at 5VDC\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\u003ctable border=\"1\"\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel\u003c\/td\u003e\n\u003ctd\u003eHE693THM884\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eChannels\u003c\/td\u003e\n\u003ctd\u003e8\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSupported Types\u003c\/td\u003e\n\u003ctd\u003eJ, K\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eResolution\u003c\/td\u003e\n\u003ctd\u003e0.1 degC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eA\/D Conversion\u003c\/td\u003e\n\u003ctd\u003e18-Bit Integrating\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Impedance\u003c\/td\u003e\n\u003ctd\u003e\u0026gt; 20 Mohms\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMax Sustained Input\u003c\/td\u003e\n\u003ctd\u003e+\/- 35V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCommon Mode Rejection\u003c\/td\u003e\n\u003ctd\u003e\u0026gt; 100 dB\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Consumption\u003c\/td\u003e\n\u003ctd\u003e100mA @ 5VDC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temperature\u003c\/td\u003e\n\u003ctd\u003e0 to 60 degC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHumidity\u003c\/td\u003e\n\u003ctd\u003e5% to 95% (non-condensing)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch3\u003eInstallation Guidelines\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eEnsure the PLC is powered down before inserting or removing the module from the rack.\u003c\/li\u003e\n\u003cli\u003eUse shielded thermocouple extension wire to minimize noise interference in industrial environments.\u003c\/li\u003e\n\u003cli\u003eConnect the cable shield to a reliable earth ground point to maintain signal integrity.\u003c\/li\u003e\n\u003cli\u003eAvoid routing thermocouple signal cables near high-voltage lines or high-EMI sources (e.g., VFDs, contactors).\u003c\/li\u003e\n\u003cli\u003eVerify that the terminal block is properly seated to ensure accurate cold junction compensation.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\u003ch3\u003eWhat does the HE693THM884 do?\u003c\/h3\u003e\u003cp\u003eIt is an analog input module that allows 8 thermocouples to be connected directly to a Series 90-30 PLC, handling the signal processing and cold junction compensation internally.\u003c\/p\u003e\u003ch3\u003eWhat is the main power supply required?\u003c\/h3\u003e\u003cp\u003eThe module consumes 100mA at 5VDC, which is supplied directly from the PLC backplane.\u003c\/p\u003e\u003ch3\u003eHow does the module handle broken sensors?\u003c\/h3\u003e\u003cp\u003eThe module includes an open-circuit alarm bit for each of the eight channels, which allows the PLC program to detect and respond to a broken thermocouple wire.\u003c\/p\u003e","brand":"General Electric","offers":[{"title":"Default Title","offer_id":50464600621308,"sku":"HE693THM884","price":99.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0787\/9983\/1292\/files\/wm_1_a4cedba8-50c4-4127-8dd7-108f74a59d28.jpg?v=1784691244","url":"https:\/\/www.electronicplc.com\/es\/products\/ge-fanuc-he693thm884-series-90-30-thermocouple-input-module","provider":"Electronic PLC","version":"1.0","type":"link"}
