Serial data input Digital Panel Meter slaves


The Intuitive series of digital panel meter slaves and controllers accept most common ASCII signals such as RS232, RS422 and RS485 and we also have versions to accept T24 wireless data.

INT4-S ASCII data input RS232 or RS485 digital slave display - easy to use!

The INT4-S is our most popular 1/8 DIN panel meter which accepts common serial ASCII data signals such as RS232, RS422 and RS485 and T24.

Technical operating manuals for digital panel meters available with instant access

Precise ...
This digital panel meter is easy to use and can select data to display from complex strings. You can set the display to have 2, 3, 4, 5 or 6 digits, depending on the type of measurement you want to make. You can even scale the numeric value and apply an offset - handy for converting from imperial to meteric, oF to oC etc.

Flexible ...
This panel meter can be fitted with isolated output signal modules to add control and data sharing functions.

Tamper Proof ...
This digital panel meter is also available with a plain front panel. All settings can be locked to prevent changes after commissioning.

The small window in the bottom right can have text such as kg, te, kN, lbs, oC, oF etc.
The display colour is available in red or green.
