CUSTOMIZABLE PRODUCT: This product is available in custom configurations for OEMs and high volume orders (over 100 pieces). If you have a difficult application that requires our engineering input, please call 1-888-652-4757 so we can assist you.
What it does:
The Merlin accepts one of several popular input signal types to display.
With programmable panel meters one slip of the finger can be the root of many headaches. But with the Merlin you don’t have to worry! There’s no buttons on the unit so you don’t need to stress about accidental parameter alterations during handling. Instead set-up is via your PC using a USB connection.
Sending to another country with a different voltage? Worried about the unit getting fried? Relax.
The Merlin accepts 24-250V AC or 19.5-250V DC making it a truly universal unit suitable for anywhere in the world. So now there’s no need to stock separate high voltage and low voltage units, now you just need one: this one!
It doesn't get much simpler than this. No more reading hefty manuals or frustrating delays. You'll experience the rare joy of getting your application up and running sooner and afterwards you'll wonder why you've tolerated difficult setups all this time.
Yes, you heard us correctly. You can configure the unit directly using the Merlin's excitation voltage. You'll be surprised how easy we've made it.

The Merlin process indicator accepts analog inputs from a range of industrial sensors, including: process, temperature, flow, frequency, and voltage from 200mV to 300V. It features a wide range power supply that suits both AC mains and 24V DC applications, and supplies the excitation required for common sensors and transmitters.
The Merlin digital panel meter can be scaled into any engineering unit, and the result displayed on the large 0.8” 4 digit super-bright LED display. Auto ranging is available to increase the dynamic range of viewable data. The Merlin R2A adds two Form A 3 Amp relays for a variety of control and alarm functions, and a 4-20mA active output for retransmission to PLCs and SCADA systems.
This panel indicator has been designed for harsh industrial environments. With an IP65 sealed bezel and extensive testing of noise effects to and beyond CE requirements, the Merlin LED panel meter provides a tough and reliable application solution.
The unit boasts a 1 minute setup time using the Define Toolbox configuration software. All functions and features are explained expertly in the dynamic sidebar help - perfect for the novice starting out who can use it to learn about industrial sensors and applications, or the expert who wants to save commissioning time.
