Original Germany Siemens 6ES7431-1KF00-0AB0 SM431 8-Channel Group Isolated Analog Input Module 13Bit For S7-400 PLC
Complete order number: 6ES7431-1KF00-0AB0
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 differential analog inputs, 4 channels for 1 group of inter group optoelectronic isolation, a total of 2 isolated channels
Conversion resolution: 13 bits for voltage signal (including sign and over range bits), 14 bits for current signal; 25 ℃ basic error ± 0.4%~± 0.7% FS
Support the collection of signal types (STEP7 software configuration selection)
Voltage signal: ± 10V, ± 5V, ± 2.5V, 1-5V, ± 1V
Current signal: ± 20mA, 0~20mA, 4~20mA (can be powered by external DC24V for two-wire transmitters)
Resistance signal: 0~600 Ω (only the first 4 channels support resistance sensor acquisition)
⚠️ Thermocouples and Pt100 thermistor temperature acquisition are not supported. Temperature measurement requires the use of 7KF/7QH series SM431 module
Conversion cycle: Single channel fastest 66ms, built-in 50Hz/60Hz power frequency filter, can suppress high-frequency interference from frequency converters and servos
