Absolute 4300GEXTSUP DC To DC Transmitter

The API 4300 G EXTSUP is a galvanically isolated DC-to-DC transmitter that converts a wide input signal (0-100 mV to 0-500 V DC) into a 4-20 mA current output, enabling precise signal transfer from voltage sensors to plant controllers such as Absolute PLCs. If you order the EXTSUP option, the transmitter provides an open-collector sinking output that operates unpowered, offering flexibility for unpowered signal paths in mixed electrical environments. The unit supports DIN-rail or panel mounting, and for passive input devices it can be powered by an 18 V DC supply, simplifying integration with a variety of sensors. Compatible with Absolute controllers and other major brands, API 4300 G devices are factory-configured to your chosen input range, delivering a reliable, isolated signal path that helps protect control systems from ground loops and voltage transients in industrial settings.
