Product Description Product Overview:HT218M LCD isolation intelligent temperature transmitter is used for RTD, thermocouple (TC), resistance (Ω), signal input, two-wire system 4-20mA analog output, and the configuration is via RS485 (MODBUS RTU protocol) or HART protocol.Features:Input signal supports 2 RTDs, 10 thermocouplesInput signal is fully switchable4~20mA output, RS485,HART optionalThermocouple cold end compensationResponse time≤700mSInput and output isolation, good anti-interference effect Parameters: Input signalRTDs and thermocouplesCold-end compensation temperature range-20~70oCCompensation accuracy±1oCOutput signal4~20mA, or 4~20mA plus HART protocolLoad resistanceRL≤(Ue- 14)/0.021Overflow alarm output currentat the upper and lower limits.IH=21mA, IL=3.8mAPower supply DC16~40VTemperature drift0.015%FS/oCResponse timereaches 90% of the final scale within 1sAmbient temperature in use-20~70oCDielectric strength1500Vrms(in 1 min)electrical insulation resistance>=100MΩ (500VDC) Input type and transmission accuracyInput CodeTypeMeasuring temperature RangeMin. measuring rangeConversion accuracy (whichever is greater)RTDPt100Pt100-200.0~850.0oC20oC±0.1%FS or ±0.2oCCu50Cu50-50.0~150.0oC20oC±0.1%FS or ±0.2oCTC(thermocouples)TC-BB400~1800oC500oC±0.1%FS or ±1.5oCTC-EE-100~1000oC50oC±0.1%FS or ±0.5oCTC-JJ-100~1200oC50oC±0.1%FS or ±0.5oCTC-KK-180~1372oC50oC±0.1%FS or ±0.5oCTC-NN-180~1300oC50oC±0.1%FS or ±0.5oCTC-RR-50~1768oC500oC±0.1%FS or ±1.5oCTC-SS-50~1768oC500oC±0.1%FS or ±1.5oCTC-tT-200~400oC50oC±0.1%FS or ±0.5oCNote: 1. The above accuracy data is tested under the condition of ambient temperature of 20oC±2oC. 2. The output accuracy "%" is relative to the set range. 3. Thermocouple measurement also need to add the cold end compensation error, internal cold end compensation error ≤ ± 1 oC.Structure Drawing: Wiring:Related Products:Certification:FAQ:1.
