What is the Wago 750-492/040-001?

This analog input module processes differential signals ranging from 4 to 20 mA.

The input signal is transmitted with a resolution of 13 bits.

The channels are electrically isolated from one another and from the system level.

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: Non-linear limiting

The device is ideal for operation in extreme environments thanks to:

An extended temperature range

Greater immunity to impulse voltages and electromagnetic interference

Higher vibration and shock resistance
