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 \u2103 basic error \u00b1 0.4%~\u00b1 0.7% FS
Support the collection of signal types (STEP7 software configuration selection)
Voltage signal: \u00b1 10V, \u00b1 5V, \u00b1 2.5V, 1-5V, \u00b1 1V
Current signal: \u00b1 20mA, 0~20mA, 4~20mA (can be powered by external DC24V for two-wire transmitters)
Resistance signal: 0~600 \u03a9 (only the first 4 channels support resistance sensor acquisition)
\u26a0\ufe0f 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
Transmission distance: Shielded twisted pair cable with a maximum length of 200 meters for wiring
Power supply parameters: external DC24V load power supply (transmitter maximum power supply 400mA); The maximum consumption of 5V backplane is 350mA, and the typical overall power consumption is 1.8W
Wiring accessories: 40 pin front connector (6ES7492-1AL00-0AA0) needs to be purchased separately, and the module does not include wiring terminals at the factory
Physical specifications: S7-400 single slot UR rack installation, dimensions 25mm \u00d7 290mm \u00d7 210mm, net weight approximately 500g
Diagnostic function: basic process fault alarm, support for over range fault detection, no disconnection diagnosis interrupt function
Working environment: 0 \u2103~+60 \u2103 rack operating temperature, storage -40 \u2103~+85 \u2103, IP20 protection, in compliance with industrial EMC anti-interference standards
