Model TSA202

Short Description

The TSA202 is a  current loop transmitter with 0-20mA/4-20mA input range. The current loop input is galvanically isolated from the interface.

Analog input module TSA202 is a dual-channel device utilizing the 1-Wire digital protocol. It offers a reliable and accurate solution for measuring a variety of analog signals in industrial and automation environments. The analog inputs are galvanically isolated from the communication interface, ensuring signal integrity and robust protection against electrical interference.

The TSA202 supports two selectable input modes: 0–20 mA current loop and 0–10 V voltage input. The extended 0–20 mA range allows not only the handling of standard 4–20 mA measurement signals but also the detection of special conditions such as sensor faults, calibration states, or other diagnostic outputs that may fall below the 4 mA threshold.

The input mode applies to both channels simultaneously.

The TSA202 is suitable for measuring both electrical and non-electrical parameters when paired with appropriate external sensors. The raw analog values—whether current (mA) or voltage (V)—can be easily converted into meaningful measurement units using an offset and multiplier defined in the master controller.

This allows seamless integration with a wide variety of sensor outputs, making the TSA202 an essential component for high-accuracy analog data acquisition over a digital interface. It offers outstanding flexibility, ease of use, and broad compatibility with different sensor types and applications.

Analog input module applications
