1. General Description
This user’s manual describes the specification, name of each part, wiring, etc.
of the following modules, which can be used with the MELSEC-A series
AnS/QnAS CPU module (abbreviated as PC CPU from here on).
l
A1S64TT-S1 Temperature Control Module
(abbreviated as A1S64TCRT-S1 from here on)
l
A1S64TCRTBW-S1 Temperature Control Module
(abbreviated as A1S64TCRTBW-S1 from here on)
1. A1S64TCRT-S1
The A1S64TCRT-S1 is a special module that performs temperature
adjustment, which converts the external platinum temperature-measuring
resistor input value to a digital value in 16-bit encoded BIN format and
performs PID operation automatically.
2. A1S64TCRTBW-S1
The A1S64TCRTBW-S1 is a module which enhances the A1S64TCRT-S1
with a function to detect the disconnection of the input power to the
controlling device.
3. Temperature input and control output type
The temperature input type and control output type of each temperature
control module are indicated below:
