Analog current temperature transmitter [4-20mA], 1s Max-AT-1I MAX-AT-1I

Current temperature transmitter – precise measurement and reliability

This analog temperature transmitter, designated MAX-AT-1I, is used for precise temperature measurement using an external sensor. It converts the temperature value into a standardized current signal in the range of 4-20 mA, ensuring compatibility with a wide range of control and monitoring systems. The device is particularly useful in industrial applications where reliability and measurement accuracy are required.

### Key features and application

The MAX-AT-1I transmitter is a modular design, making it easy to integrate with existing systems. The 4-20 mA output signal is a standard in industrial automation, allowing easy connection to PLCs, data loggers or other measuring devices. The transmitter works with resistive temperature sensors, providing flexibility in choosing the appropriate sensor for a specific application. This makes it possible to monitor temperature in various technological processes, HVAC systems or environmental monitoring.

**Measurement range** of the transmitter is from -50°C to 100°C, allowing it to be used in a wide range of temperatures. **Ambient temperature**, in which the transmitter can operate without interference, is from -20°C to 50°C. The use of a noise filter at the signal output ensures a stable and precise measurement even in environments with a high level of electromagnetic interference. This allows signal cables up to 300 meters long to be routed without fear of signal quality loss.

### Technical specifications and mounting

The device is powered by a voltage of 9-30 V DC, providing flexibility in choosing a power source. Mounting is done on a standard TH-35 rail, making installation and replacement easy. Compact dimensions (1 module – 18 mm) allow for efficient use of space in control cabinets. The transmitter has screw terminals 2.5 mm² for connecting power and signal cables and provides a tightening torque of 0.4 Nm for a secure connection. Protection class IP20 protects the device against touching with fingers and access to small objects.
