Analog Modules for Temperature Measurement
Temperature measurement by
thermocouple
These modules are designed to conver t external
platinum temperature-measuring resistor input
values into16 or 32-bit signed binary tempera
-
ture measurement values and scaling values.
The reference temperature is determined by
means of a thermocouple for the Q64TD and
Q64TDV-GH.
앬
Temperature of 4 channels can be measured
by one module
앬
Two kinds of platinum temperature measur-
ing resistors (Pt100, JPt100) compliant with
JIS and IEC standards are supported
앬
The disconnection of a platinum tempera
-
ture-measuring resistor or cable can be
detected on each channel
앬
Selection of sampling processing/time aver
-
aging processing/count averaging processing
앬
Error compensation by offset/gain value set
-
ting
앬
Alarm output when limit value is exceeded
앬
Potential isolation between process and con-
trol by means of an optocoupler is a standard
feature. Additional potential isolation
between the channels for the Q64TDV-GH
앬
The module is provided with a removable
terminal block fastened with screws
