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.

4. PRINCIPLES OF OPERA TION

4.1 Loop Isolation T ype (for SDBT -1 1 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 .

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.

(e) Call the adjustment item (P: ADJUST) . (f) P03: ZERO ADJ1 is displayed. (g) Apply an input equivalent to 0 % of the input range. Check the input value and the input display of P03: ZERO ADJ1. If the input value does not correspond to the display value , select P03: ZERO ADJ1 to enter the adjustment mode. Mainly select INC (addition) or DEC (subtraction) for adjustment. (Selecting RST resets the adjusted value and re trieves the factory-set default.) Selecting HINC or HDEC performs adjustment using a value ten times as large as INC or DEC. (h) Apply an input equivalent to 100 % of the input range. Check the input value and the in put display of P04: SP AN ADJ1. If the input value does not correspond to the display value, select P04: SP AN ADJ1 to enter the adjustment mode. Mainly select INC (addi tion) or DEC (subtraction) for adjustment. (Selecting RST resets the adjusted value and retrieves the factory-set default.) Selecting HINC or HDEC performs adjustment using a value ten times as large as INC or DEC. (i) After completing the adjustment, set the parameter write protect (W.P.) of setting jumper to ON. (Refer to ‘‘5.2 Setting Jumper’’.)

6.3 Replacement of Fuse

When the fuse blows or requires replacement, replace it according to the following procedure. Recommended replacement interval: About 3 years.

NOTE

• When the fuse below , first check for the case because the fuse itself may not be responsible for the problem. Then change the fuse.

• Use the dedicatd fuse (S9510VK). Do not use a fuse for other products.

(1) T o remove the fuse holder cap, then pull the fuse out in the direction shown in Figure 6

-3.

(2) When installing a new fuse, use a fuse with the correct rating. Fasten the cap se-

curely.

Appendix-1 GENERAL

If you specify the terminal block to which the power source is directly connected (suffix code /TB), the external wiring to the terminal block is necessary; therefore, drawing out of the internal unit requires previous turning off of the power source and disconnection of the wiring from the terminal block.

Appendix-4 POWER SUPPLY AND GROUND WIRING

(1) All cable ends must be furnished with crimp-on type solderless lugs (for 4 mm screw). (2) Examples of applicable cables:

Cross-sectional area of the cable conductor: 2.0 mm Applicable cable: 600 V vinyle insulated cable (IV) stranded wires, conforming to JIS C3307.

Vinyle sheathed cables for electric appliances (KIV) stranded

wires, conforming to JIS C3316.

Note *: Power supply cables should be determined from the instrument power consumption-they must have

conductors with cross-sectional area of at least 1.25mm2.

(3) Wirings to power supply and ground terminals should be made after completion of

signal terminal wirings. (To facilitate connecting input signal, pull the internal unit approximately half way out of the housing. Do not remove the power terminal block.)

(4) After completing the power supply and ground wiring, mount the power terminal cover.
