WEIDMÜLLER has released the PMX420 universal indicators for current/voltage signals. They are the latest additions to the PMX series of industrial displays.

The PMX420 base model accepts any common current or voltage format, then isolates, filters and scales the input signal to provide a clean, bright, four-digit LED display in engineering units. It also increases loop reliability by providing power for active input devices.

The PMX420Plus adds four alarm channels (each with it's own status indicator and relay contact outputs) and a fully isolated analogue current/voltage output.

Users can set up all aspects of the instruments' operation from the front panel keypad. Other features include maximum and minimum recall, inbuilt square law signal linearisation, siren and group alarm functions and the option for manual or automatic alarm reset.

Advances in technology mean that either model can use any common ac or dc power supply voltage without modification.
