THE PMX420 series current/voltage displays available from Weidmuller are the latest additions to the PMX series of industrial displays.

There are two models: the base model PMX420, and the fully optioned PMX420Plus.

The 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 its own status indicator and relay contact outputs) and a fully isolated analogue current/voltage output.

All aspects of the instruments' operation can be setup to suit an application from the front panel keypad. There are also several other handy features like 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.
