Complete order number: 6ES7431-0HH00-0AB0
Product model: SM 431 16AI analog input module (economical, no electrical isolation)
Adaptation system: Siemens SIMATIC S7-400 full series CPU, S7-400H redundant hot standby control system
Origin: Made in Germany
Channel configuration: 16 single ended analog inputs, module without electrical isolation design, suitable for low interference conventional scenarios inside the control cabinet
Conversion accuracy: 13 bit resolution (including sign bit and over range bit), typical basic error \u00b1 0.5% FS at 25 \u2103
Support the collection of signal types (STEP7 software configuration selection)
Voltage signal: \u00b1 10V, 0~10V, 1~5V, \u00b1 1V
Current signal: \u00b1 20mA, 0-20mA, 4-20mA, can directly provide DC24V power supply for two-wire field transmitters
\u26a0\ufe0f Important limitation: Thermocouples, Pt100 thermistors, and resistance sensors are not supported for temperature measurement and collection. Only standard voltage and industrial current signals can be collected
Conversion cycle: Single channel conversion time 55\/65ms, full channel cyclic scanning cycle 1040ms; built-in 50Hz\/60Hz power frequency interference filter, can suppress conventional power grid harmonic interference
Cable transmission distance: shielded twisted pair cable maximum wiring distance of 200 meters
Power supply parameters: external DC24V load power supply, transmitter maximum output current 400mA; backplane 5V maximum consumption 100mA, typical overall power consumption 2W
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
Hardware specifications: S7-400 single slot UR rack installation, size 25mm \u00d7 290mm \u00d7 290mm, net weight approximately 520g
Diagnostic function: Only supports over range fault alarm, without interruption function for wire breakage detection and short circuit diagnosis. The diagnostic ability is weaker than the high-precision models of 7KF and 7QH series
Working environment: 0 \u2103~+60 \u2103 rack operating temperature, storage -40 \u2103~+85 \u2103, IP20 protection, in compliance with industrial EMC basic standards
