2.1 Properties
Analog Input Module AI 8xU/R/RTD/TC HF (6ES7531-7PF00-0AB0)
12 Manual, 09/2016, A5E36647959-AB
The module has the following technical properties:
● 9 electrically isolated analog inputs
● Measurement type can be set for each channel:
– Voltage
– Resistor
– Thermal resistor (RTD)
– Thermocouple (TC) including external compensation via CH 8 (reference channel)
● Resolution 16 bits including sign
● Two operating modes:
– Fast: shortest integration time 2.5 ms
– Standard: shortest integration time 7.5 ms
● Configurable diagnostics (per channel)
● Hardware interrupt on limit violation can be set per channel (two low and two high limits
per channel)
● Supports thermoresistors and thermocouples according to the GOST standard
The module supports the following functions:
