The ABB GJR2344300R1000 88TU01C-E is a high-precision thermocouple temperature acquisition module engineered for harsh industrial environments,delivering exceptional accuracy and reliability for critical temperature monitoring applications.Its 16-bit ADC resolution and automatic cold-junction compensation(CJC)ensure±0.1°C measurement accuracy at 25°C for K-type thermocouples—five times more precise than standard 12-bit modules—critical for pharmaceutical cold storage and chemical reactor control where even minor temperature fluctuations compromise product quality.
With 2500V AC channel-to-channel isolation,the module effectively rejects electromagnetic interference(EMI)from nearby high-power equipment,maintaining stable readings in steel mill hot rolling workshops and power plant boiler rooms—environments where standard modules often fail.It supports 8 thermocouple types(J/K/T/R/S/E/B)and seamlessly integrates with ABB’s AC800M and legacy DCS 600 systems,eliminating the need for costly protocol converters.Operating from-40°C to 70°C and certified for hazardous areas(ATEX),the ABB GJR2344300R1000 88TU01C-E minimizes downtime,enhances process control,and stands as a trusted solution for industrial temperature measurement.
然后看现场需求,要是你需要测热电偶信号,通道数≤8路,还得支持多种类型热电偶,选它准没错;要是测热电阻(PT100),得选ABB专门的热电阻模块(比如GJR2344301R1000),别硬用这个,不然精度不够。还有,要是在防爆区用,得确认它的ATEX认证符合现场等级,它是Ex II 3G Ex nA IIC T4 Ga,适合Zone 2/22的防爆场合,Zone 0/1就不能用,得选更高级别的防爆模块。
