General Description
The Merlin universal digital indicator accepts
analog inputs from a range of industrial sen-
sors, 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 applica-
tions, 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.
