SITRANS RD300
The SITRANS RD300 is a panel mounted digital display for process
instrumentation and acts as a multi-purpose, easy to use rate/totalizer ideal for
flow rate, total, and control applications. It accepts current and voltage signals (e.g.
4-20 mA, 0-10 V). Three of the front panel buttons can be custom-programmed for
specific operation.
The basic model includes an isolated 24 VDC transmitter power supply that can
be used to power the input transmitter or other devices. An additional isolated
24 VDC power supply is included with the 4-20 mA output option. A digital input,
F4, is standard.
A fully loaded RD300 rate/totalizer meter has the following: four SPDT relays,
4-20 mA output, and two 24 VDC power supplies. The RD300 capabilities may be
enhanced by adding the following external expansion modules: four SPST relays
(creating an eight-relay rate/totalizer), two digital I/O modules with four inputs and
four outputs each, and USB, RS-232 or RS-485 communication adapters.
The eight relays can be used for alarm indication or process control applications. The
4-20 mA isolated output, Modbus RTU serial communications, and digital I/O options
make the RD300 an excellent addition to any system.

INSTALLATION
There is no need to remove the meter from its case to
complete the installation, wiring, and setup of the meter for
most applications. Instructions are provided for changing the
transmitter power supply to output 5 or 10 VDC instead of 24
VDC, see Transmitter Supply Voltage Selection on page 6.
Unpacking
Remove the meter from box. Inspect the packaging and
contents for damage. Report damages, if any, to the carrier.
If any part is missing or the meter malfunctions, please contact
your supplier or the factory for assistance.
Panel Mounting Instructions
 Prepare a standard 1/8 DIN panel cutout – 3.622" x 1.772" (92 mm x
45 mm). See graphic below for more details.
 Clearance: allow at least 6.0" (152 mm) behind the panel for wiring.
 Panel thickness: 0.04" - 0.25" (1.0 mm - 6.4 mm).
Recommended minimum panel thickness to maintain Type 4X
rating: 0.06" (1.5 mm) steel panel, 0.16" (4.1 mm) plastic panel.
 Remove the two mounting brackets provided with the meter (back-off the two
screws so that there is ¼" (6.4 mm) or less through the bracket. Slide the
bracket toward the front of the case and remove).
 Insert meter into the panel cutout.
 Install mounting brackets and tighten the screws against the panel. To
achieve a proper seal, tighten the mounting bracket screws evenly until
meter is snug to the panel along its short side. DO NOT OVER TIGHTEN,
as the rear of the panel may be damaged.
