The analog input module receives differential signals of values ± 10 V DC or 
0 V ... 30 V.
The input signal of each channel is electrically isolated and will be transmitted 
with a resolution of 14 bits.
The internal system supply (via the data bus contacts) is used for the power 
supply of the module. 
The shield (screen) is directly connected to the DIN rail.
• Measured-value acquisition: time synchronous (both inputs)
• Overrange / measuring range underflow: status byte and LED
• Method of conversion: SAR (Successive Approximation Register)
• Operating mode: continuously sampling (preset)
• Protection: RC circuit
