The 2-channel analog input module processes differential signals of a
magnitude ±10VDC.
The input signal of each channel is electrically isolated and is transmitted with
a resolution of 13 bits.
System voltage is used for voltage supply.
The shield (screen) is directly connected to the DIN rail.
• Measured-value acquisition: time synchronous (both inputs)
• Measuring range overflow/underflow: status byte and LED
• Method of conversion: SAR (Successive Approximation Register)
• Operating mode: continuously sampling (preset)
• Protection: RC circuit
Technical data for the 750-479/000-001 model:
• Measured-value acquisition time synchronous (in connection with
synchronized sampling of the slave, 750-303 Fieldbus Coupler (as from
version 0101))
• Overrange / measuring range underflow status byte, status bits, measured
value and LED (min./max. limiting values can also be set according to
customers’ specifications)
• Sampling delay (instruction/conversion) < 50µs
• Operating mode triggered
