Product model: SM 431 16AI multifunctional isolated analog input module
Adaptation system: Siemens SIMATIC S7-400 full series CPU, S7-400H redundant hot standby control system
Origin: Made in Germany
Channel configuration: 16 analog differential inputs (voltage\/current\/thermocouple); 8 channels can be used for thermal resistance and resistance signal acquisition
Electrical isolation: There is photoelectric isolation between the analog input side and the PLC backplane bus, with a maximum isolation withstand voltage of 120V AC common mode voltage and strong resistance to industrial interference
Conversion accuracy: 16 bit resolution (including symbols and over range bits), 25 \u2103 basic error \u00b1 0.15% FS, full temperature range \u00b1 0.3% FS
Support signal types (STEP7 software can be freely configured)
Voltage signals: \u00b1 10V, 0~10V, 1~5V, \u00b1 1V, \u00b1 500mV, \u00b1 100mV, \u00b1 50mV, \u00b1 10mV, \u00b1 5mV
Current signal: \u00b1 20mA, 0~20mA, 4~20mA (can directly supply power to two-wire transmitters)
Thermocouple TC: B\/E\/J\/K\/L\/N\/R\/S\/T\/U All types of thermocouples, supporting cold junction temperature compensation
Thermistor RTD: Pt100, Pt200, Pt500, Pt1000, Ni100, Ni1000, four wire\/three wire temperature measurement system
Resistance signal: collected by 0-5k \u03a9 resistance sensor
Conversion cycle: The fastest single channel is 6ms, supporting 50Hz\/60Hz power frequency interference suppression, and software can set the integration time to filter out frequency converter interference
Cable specifications: Voltage\/current shielded cable with a maximum length of 200 meters; Thermocouple signal cable up to 50 meters long
Power supply parameters: external DC24V (supplying power to two-wire transmitters, maximum 400mA); Backplane 5V maximum consumption 700mA, typical power consumption 4.5W
Wiring accessories: It needs to be used with a 40 pin front connector (6ES7492-1AL00-0AA0), and the module does not include terminals at the factory
Hardware specifications: S7-400 single slot installation, dimensions 25mm \u00d7 290mm \u00d7 210mm, net weight approximately 700g
Diagnostic function: supports wire breakage detection, over range alarm, short circuit fault diagnosis, can trigger diagnostic interruption, upper\/lower limit alarm interruption
Working environment: 0 \u2103~+60 \u2103 rack operation, storage -40 \u2103~+85 \u2103, IP20 protection, in compliance with industrial EMC standards
