Description
YOKOGAWA AI3351 Communication module
AI3351 safety I/O module can be directly connected to the transmitter on the hazardous side to isolate the sensing signals generated by the transmitter from the hazardous side and then transmit them, and provide isolated power supply to the transmitter on the hazardous side. Insulation strength (intrinsically safe end and non-intrinsically safe end): 2500Vac (1min); electromagnetic compatibility: in line with GB/T18268 industrial equipment application requirements, anti-interference degree, etc. Level 4a; explosion-proof certification: [Ex ia] IIC;
AI3351 includes UW5831 dual ModbusRTU communication module, UW5832 dual CNet (UW) communication module, UW5833 Profibus DP slave communication module and UW5836 GSM wireless transmission module, etc., to meet the access requirements of heterogeneous equipment nodes in the field; and to support the dual or triple redundancy configuration of communication modules;
AI3351 implements analogue channel data type selection, programmable amplification, data acquisition, fault diagnosis, digital filtering, temperature compensation, linear correction, engineering conversion, etc., and supports universal input of analogue signals in industrial field (voltage/current/thermistor/thermocouple, including voltage: 0-10mV, 0-20mV, 0-100mV, 0-5V; current: 0-10mA, 0-20mA, 4-20mA; RTD: Pt100, Cu50; thermocouple: B, E, J, K, S, T type), signal type software configuration; automatic compensation for ambient temperature and zero and gain correction, full-range high precision, calibration-free, maintenance-free; 20mA output distribution voltage > 15V, reducing the supporting costs and engineering, significantly improve the system’s anti-interference and stability. The 20mA output distribution voltage is >15V, which reduces the supporting cost and engineering quantity, and significantly improves the system anti-interference and stability;
