Item no. 750-480

2-channel analog input; 0 … 20 mA; Differential input; light gray


The 2-channel analog input module processes differential signals of a magnitude 0–20mA.

The input signal of each channel is electrically isolated and is transmitted with a resolution of 13 bits.

The internal system supply powers the module.

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: non-linear limiting
