2 CH A/I 0-30VDC DIFFERENTIAL

2-channel analog input - 0 ... 30 VDC; Differential input


This analog input module processes differential signals ranging from 0 to 30 VDC. The input signal of each channel is electrically isolated and is transmitted with a resolution of 14 bits.

The system supply powers the module. The shield directly connects to the DIN-rail.

• Measured value acquisition: Time synchronous within the module
• Measurement range overflow/underflow: Status byte and LED
• Conversion method: SAR (Successive Approximation Register)
• Operating mode: Continuously sampling (default)
• Protection: RC circuit
