SITRANS RD200

SITRANS RD200

SITRANS RD200 is a universal input, panel mount remote digital display for process
instrumentation.

It accepts a single input of current, voltage, thermocouple, or RTD signals, and the four
front panel buttons make the setup and programming an easy task.

The isolated 24 V DC transmitter power (optional) can be used to power the input
transmitter, the 4 to 20 mA output, or other devices.

Two relays (optional) can be used for alarm indication or process control applications,
such as alternating pump control.

4-20 mA isolated output and Modbus® RTU serial communication options make
SITRANS RD200 an excellent addition to any system.

WARNING:

• Use copper wire with +60 °C or +60/75 °C (+140 °F or +140/167 °F)
insulation for all line voltage connections.

• Observe all safety regulations.

• Electrical wiring should be performed in accordance with all
applicable national, state, and local codes to prevent damage to

Current and Voltage Connections

Connections

The following figures show examples for current and voltage connections.

There are no switches or jumpers to set up for current and voltage inputs. Setup and
programming is performed through the front panel buttons.

The current input is protected against current overload by a fuse capable of being reset.
The display may or may not show a fault condition depending on the nature of the
overload.

The fuse limits the current to a safe level when it detects a fault condition, and
automatically resets itself when the fault condition is removed.

Notes:

• The meter is factory calibrated prior to shipment, for all input types, in
milliamps, volts, and degrees respectively.

• The calibration equipment is certified to NIST standards.

There are no jumpers involved in the setup of the meter. The RTD/TC selector switch,
located between the SIGNAL and SERIAL connectors, must be set accordingly for the
meter to accept RTD or thermocouple inputs. See Connector Labeling diagram on
page 11.

Setup and program the device using the front panel buttons.

After power and signal connections have been completed and verified, apply power to
the meter.
