Product description

The Siemens 7NG3242-0AA00 is a SITRANS TW universal transmitter designed for rail mounting in a four-wire system. This version does not include explosion protection. It operates on a power supply of 230V AC/DC and provides an output signal of 0/4 to 20mA. The transmitter accepts input for temperature sensors, resistance-based sensors, and mV sources, with a measuring range of -120 to 1000 mV.

This transmitter is ideal for converting various sensor signals into a standard 4-20mA current loop for process control systems. It is commonly used in industries such as chemical processing, oil and gas, power generation, and water treatment for monitoring temperature, pressure, and other process variables.

Stanlo Automation, a veteran-owned surplus distributor, offers the Siemens 7NG3242-0AA00. We provide reliable, high-quality industrial automation components, ensuring your process control systems are accurately monitored and controlled.
