Simpson Electric M2400930F Digital Panel Meter is a 4-digit LED temperature indicator designed for panel mounting that accepts a Pt100 RTD input and is powered from 85–250 VAC. The "F" suffix indicates Fahrenheit display, so it shows temperature readings in °F for PT100 RTD sensing. This unit is used in industrial panels for temperature monitoring and process control, pairing with Pt100 sensors for temperature measurement in control systems, and it is part of Simpson's M240 family of digital panel meters.
