Number of Units
The Heat/Cool Temperature Control Unit belongs to the C200H Special I/O Unit
group. A maximum of ten Special I/O Units (including PC Link Units) can be
mounted on each of the following Racks: CPU Rack, Expansion I/O Rack, and
Slave Rack.
Note Configure the Units such that the maximum current supplied for each Rack is
greater than or equal to the total current consumption for the Units.
Refer to the
C200H PC Operation Manuals
.
The number of Special I/O Units used with a Slave Rack is limited by data trans-
mission considerations, as shown in the table below. The numbers in the table
indicate the maximum number of Units of groups A, B, C, or D which can be used
with a single Slave Rack.

2 units max.
Note
1. When a combination of Units from groups A, B, C, and D is used, the number
from each group must satisfy both the following equations:
3A + B + 2C + 6D
≤
12
A + B + C + D
≤
8
2. Other Units can be added until the total number of Units reaches ten. If PC
Link Units are used, the number of Units including the PC Link Units must
not exceed ten.
Precautions
The IR area of the C200H Special I/O Unit is allocated according to the setting of
the unit number switch on the front panel,
not
the address of the slot where the
unit is mounted. Refer to
4-1 Memory Allocation
for the allocation of the memory
area.
Leave the two slots next to the CPU free. It is not possible to use devices con-
nected to the CPU (such as the Programming Console) if these slots are occu-
pied.
If the C200H Slave Rack is connected to another SYSMAC model Remote I/O
Master Unit, such as the C120, C500, C1000H, or C2000H, it is not possible to
use a Special I/O Unit with the C200H Slave Rack.
WARNING
Always turn the C200H power off before connecting or disconnecting a Unit,
terminal block, or output connector.
Caution
Connect thermocouples with the appropriate compensating conductor.
Wire I/O leads in separate ducts from power leads to prevent noise problems.
