2. GENERAL

The STED mV ,Temperature and Potentiometer/Voltage Converters are used to convert mV DC, thermocouple, RTD (resistance temperature detector) or potentiometer input signals to isolated two 1 to 5 V DC signals and 4 to 20 mA DC signal. Both thermocouple input type STED-210 and RTD input type STED-310 have built-in input linearizers as standard equipment. Also, an upscale or downscale burnout function is provided in all types as a standard specification.

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 by referring to Table 3-1. (d) Replace the internal unit into the rack case after completing the wiring. (e) The reference junction block (RJC) for STED-2 or STED-7 type should be securely

installed to the screw on terminal 6. (f) Always replace the terminal cover after completing the wiring.

3-1

NOTE

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.
