■ Application
The RD200 is a universal remote display for level, flow, pressure,
temperature, weighing, and other process instruments.
• 4 … 20 mA, 0 … 20 mA
• 0 V DC … 10 V DC, 1 … 5 V,
0…5V
• Type J: -50 … +750 °C
(-58 …+1 382 °F)
• Type K: -50 … +1 260 °C
(-58 …+2 300 °F)
• Type E: -50 … +870 °C
(-58 … +1 578 °F)
• Type T: -180 … +371 °C
(-292 …+700 °F)
• Type T, 0.1 resolution:
-180.0 …+371 °C
(-199.9 … +700 °F)
• 100  RTD: -200 … +750 ºC
(-328 … +1 382 ºF)
Type J: ± 1 °C (± 2 °F)
Type K: ± 1 °C (± 2 °F)
Type E: ± 1 °C (± 2 °F)
Type T: ± 1 °C (± 2 °F)
Type T, 0.1° resolution: ± 1 °C
(± 1.8 °F)
Data can be remotely collected, logged and presented from as
many as 100 displays on your local computer using the free
downloadable RD Software.
Rated operating conditions
The display accepts a single input of current, voltage, thermocouple, and RTD. This makes the RD200 an ideal fit for use with
most field instruments.
• Storage temperature range
-40 ... +85 °C (-40 ... +185 °F)
• Operating temperature range
-40 ... +65 °C (-40 ... +149 °F)
The RD200 can be set up as a standard panel mount, or combined with optional enclosures to allow it to house up to
6 displays.
• Key Applications: tank farms, pump alternation control, local
or remote display of level, temperature, flow, pressure and
weighing instrument values, PC monitoring, and data logging
with RD Software.
