2. 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.

NOTE

The fuse (S9510VK) is the dedicated fuse. Do not use it for other products.

3. INST ALLA TION

For details of the installation procedure and wiring precautions, refer to the technical information “YEWSERIES 80 Installation Manual” (TI 1B4A9-01E) or the instruction manual “Installation of Rack-Mounted Instruments” (IM 1B4F2-01E).

3.1 External Wiring

(a) T o 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.

NOTE

3-1

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.
