General Description
The Merlin universal digital indicator accepts
analogue inputs from a range of industrial
sensors, including: process, temperature,
fl ow, frequency, and voltage from 200mV to
300V. It features a wide range power supply
that suits both AC mains and 24V DC appli-
cations, and supplies the excitation required
for common sensors and transmitters.
The Merlin can be scaled into any engineer-
ing unit, and the result displayed on the
large 0.8” 4 digit super-bright LED display.
Auto ranging is available to increase the dy-
namic 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.
The unit boasts a 1 minute setup time using
the Defi ne Toolbox confi guration soft ware.
All functions and features are explained ex-
pertly in the dynamic sidebar help - perfect
for the novice starting out who can use it to
learn about industrial sensors and applica-
tions, or the expert who wants to save com-
missioning time.
The Merlin has been designed for harsh in-
dustrial environments. With NEMA 4X/IP65
sealed bezel and extensive testing of noise
eff ects to and beyond CE requirements, the
meter provides a tough and reliable applica-
tion solution.
