General Description
The TRDO23 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 applications, and
supplies the excitation required for common
sensors and transmitters.
The TDRO23A0 can be scaled into any engi-
neering 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 TDRO23A2 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 Transducers Direct TDRO23 Config Tool. All
functions are explained expertly in the dynam-
ic sidebar help - perfect for the novice starting
out who can use it to learn about industrial
applications, or the expert who wants to save
commissioning time.
The TDRO23 has been designed for harsh in-
dustrial environments. With an IP65 sealed
bezel and extensive testing of noise effects to
and beyond CE requirements, the meter pro-
vides a tough and reliable application solution.
