1-1 Nomenclature and Features
The Temperature Sensor Unit detects temperatures and sends the resultant
BCD (Binary Coded Decimal) data to the PC (Programmable Controller). This
data can be further manipulated and transferred to other I/O Units for ex-
tended system control.
The C200H Temperature Sensor Unit is available in four models. The
C200H-TS001/002 are for use with thermocouples, and can be used with K
(CA), J (IC) and L (Fe-CuNi) thermocouples. The C200H-TS101/102 are for
use with platinum resistance sensors.

1-2 System Configuration
The Special I/O Units are not allocated the word number of the slot they are
mounted to. They are allocated word numbers according to the unit number
setting on the front panel (refer to page 2).
If possible, avoid mounting the Temperature Sensor Units in either of the two
rightmost CPU Rack slots. However, if this is unavoidable, use one of the
Programming Console Base Units (C200H-BP001 or C200H-BP002) when
mounting peripheral devices to the PC.
No Special I/O Units can be mounted on a C200H Slave Rack connected to a
Master on a PC other than a C200H.
The thermocouple or RTD registers the temperature and sends the data
through the Temperature Sensor Unit to the PC in 4-digit BCD. After the PC
processes this data, the data can be output to a display, or used for control-
ling system devices.
