Specification of Westermo Industrial MD-21 DC

Overview

The MD-21 is a versatile 20 mA current loop (TTY) converter designed to enable RS-232 systems to connect to a 20 mA current loop interface over distances of up to 6 km (3.7 mi). Featuring a standard RS-232 interface with five control signals, the MD-21 ensures completely transparent communication, requiring no complex settings other than specifying whether the current loop should be active or passive. Engineered for heavy-duty industrial applications, the MD-21 offers various power options, galvanic isolation, and transient protection to guarantee reliable communication in harsh environments. It has been rigorously tested to meet stringent EMC, isolation, vibration, and shock standards, making it highly suitable for demanding industrial settings. The MD-21's flexible design supports various speeds and data bit options, allowing it to function as a standard RS-232 to 20 mA current loop converter or be connected in a ring to create a multi-drop network. Its capability to act as the current source on both transmit and receive circuits, if needed, makes the MD-21 ideal for any TTY application, ensuring reliable performance across a wide range of uses.
