Product Description:

The EL4021 is an analog output terminal. It is used for applications where precision and built-in safety diagnostics are needed. This unit incorporates short circuit and open circuit sensing to give the user with real-time line conditions and respond to fault accordingly.

The built-in output error detection facilitates system uptime. It is accessed through a 16-pin terminal block providing compact, secure wire connection. It enables integration into various I/O terminal-based systems and organized signal management. The EL4021 also provides a status sensor with an internal magnetic bond sensor that gives more function awareness and simplifies the precision of control signals. The sensor monitors internal status conditions and provides good troubleshooting or process verification. The accuracy of its output drive is ±15 mA rated to drive analog signals to downstream systems like controllers, meters, or actuators. Engineering is built in multiple analog output processes that need enough signal intensity. With diagnostic elements built-in by default, the EL4021 provides higher confidence of data genuineness and system health. It will recognize possible abnormalities before making process break-ups, cutting downtime for hand inspection. The terminal is suitable as an indication gateway in automated systems where precise output and error indication are required. Either controlling signal-controlled devices or supplying analog input to outboard modules, the terminal switches between operation and safety modes. By its own nature, it maintains signals clean and does not allow the connection errors to be realized only after being made.

Compact and tough and reliable, the EL4021 is a proven analog output solution. Where fast responsive control, diagnostic feedback in real-time, and ease of wiring are critical in applications, it adds to system reliability by continually running self-tests. The magnetic bond sensor delivers an additional layer of operating transparency to provide for stable and efficient operation.
