Complete order number: 6ES7431-7KF00-0AB0
Product Model: SM 431 8AI 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: 8-channel differential analog input, inter group optoelectronic isolation (isolation every 4 channels)
Conversion accuracy: 16 bit resolution (including sign bit and over range bit), typical basic error \u00b1 0.15% FS at 25 \u2103
Support for collecting signal types (optional STEP7 software configuration)
Voltage signals: \u00b1 10V, 0~10V, 1~5V, \u00b1 5V, \u00b1 2.5V, \u00b1 1V, \u00b1 500mV, \u00b1 250mV, \u00b1 100mV, \u00b1 80mV, \u00b1 50mV, \u00b1 20mV
Current signal: 4~20mA, 0~20mA, \u00b1 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 internal cold junction temperature compensation
\u26a0\ufe0f This model does not support Pt100 thermistor and resistance signal acquisition. The upgraded model 6ES7431-7KF10-0AB0 is required for thermistor temperature measurement
Conversion cycle: The entire module is fixed for 20ms and supports 50Hz\/60Hz power frequency filtering, which can effectively suppress high-frequency interference from frequency converters and servos
Cable transmission distance: voltage\/current shielding cable up to 200m; thermocouple compensation cable up to 50m
Power supply parameters: external DC24V load power supply (transmitter maximum power supply 400mA); The maximum consumption of 5V backplane is 1200mA, and the typical overall power consumption is 4.6W
Wiring accessories: A 40 pin front connector (6ES7492-1AL00-0AA0) needs to be separately selected, and the module does not include wiring terminals at the factory
Hardware specifications: S7-400 single slot UR rack installation, dimensions 25mm \u00d7 290mm \u00d7 290mm, net weight approximately 700g
Diagnostic function: supports wire breakage detection, input over range, short circuit fault diagnosis, can trigger hardware diagnostic interrupt, process alarm interrupt
Working environment: 0 \u2103~+60 \u2103 rack operating temperature, storage -40 \u2103~+85 \u2103, IP20 protection, in compliance with industrial EMC anti-interference standards
