General
General
The SDBT distributor is designed to supply operating power to two-wire type transmitter and
convert 4 to 20 mA DC current signals from this transmitter into output signals.
The SDBT distributor has Loop isolation type (SDBT-11 type) and Filed isolation type
(SDBT-21 type). The SDBT-11 prepares two 1 to 5 V DC output signals, and SDBT-21
prepares one 4 to 20 mA DC output signal in addition to two 1 to 5 V DC output signals. The
SDBT-11 and SDBT-21 have built-in current limiters allowing normal operation even when a
short-circuit occurs on the transmitter side.

For details of the installation procedure and wiring precautions, refer to the instruction
manual “Installation of Rack-Mounted Instruments” (IM 1B4F2-01E).
Chapter 3 Installation

3-2 IM 01B04T01-02E
3.1 External Wiring
(a) To prepare cables for connection to each terminal, install crimp-on solderless lugs for 4
mm screw on the end of each cable.
(b) Draw the internal unit out from the rack case.
(c) Connect the cables to the correct terminals referring to Table 3-1.
(d) Replace the internal unit into the rack case after completing the wiring.
(e) Always replace the terminal cover after completing the wiring.
The terminal cover cannot be replaced if the internal unit is not installed in the rack
case. The terminal cover should be securely replaced because it has the function of
locking the internal unit.

4.1 Loop Isolation Type (for SDBT-11 Type)
The SDBT-11 supplies 25.0 to 25.5 V DC to two-wire transmitter through a current limiter,
and receives 4 to 20 mA DC current signals. The current signals are converted into 1 to 5 V
DC signals, then are output through output amplifier.

4.2 Field Isolation Type (for SDBT-21 Type)
The SDBT-21 supplies 25.0 to 25.5 V DC to two-wire transmitter through a current limiter,
and receives 4 to 20 mA DC current signals. The current signals are converted into 1 to 5 V
DC signals, then are converted into digital data in A/D conversion circuit.
The digital data has signal processing (square root characteristic etc.) in microprocessor
to be Pulse Width Modulation (PWM), then is coverted into 1 to 5 V DC or 4 to 20 mA DC
signals in output circuit through optical-isolation circuit.

Items to Confirm before Start of Operation
Before you start operation, inspect and confirm the following items:
(1)Draw out the internal unit from the rack case, and make sure that the specified fuses are
properly mounted in the fuse holders at the rear of the internal unit.
(2)When inserting the internal unit into the rack case, firmly connect the multi-pin connectors
for connecting the internal unit and the case.
(3)Make sure that power plugs are properly connected to the power outlet.
(4)Make sure that external wiring to the terminal block is properly connected.
The SDBT distributor is made ready for operation by simply turning on the power once the
installation and wiring are completed. The distributor does not require parameter settings
and the like if there is no change in the specifications at order.

5.3 Setting of Parameters (for SDBT-21 Type)
This instrument has BRAIN communication parameters for specifying functions and
adjusting input. Connect JHT200 Handy Terminal (Note1) to the instrument to display or set
parameters.
Note 1: BT200 BRAIN Terminal of Yokogawa Electric Corporation can also be used.
When connecting the JHT200 Handy Terminal, the adapter for modular-jack (model
E9786WH) is required. When using the BT200 BRAIN Terminal of YOKOGAWA
Electric Corporation, the communication cable of 5-pin connector type (model
F9182EE) and the adapter for modularjack (model E9786WH) are required.
For details of operation and adjusting procedures of JHT200 Handy Terminal, refer to
the instruction manual ‘‘JHT200 Handy Terminal’’ (IM 77J50H01-01EN).
