IC200ALG630
Analog Input, 16 Bit Thermocouple, 7 Channels
Configurable Parameters
The default parameters of the Thermocouple Input module can be used in many
applications. The module can be software-configured when it is installed in a VersaMax
PLC system, or an I/O Station controlled by a Network Interface Unit that is version 2.0 or
above.
Module
Parameter
Description Default Choices
Analog Input Data
Length
Word length of the module’s analog input
data.
7 1 to 7
Analog Input Data
Reference
Starting offset for the module’s analog
input data.
user selectable
Analog Output Data
Length
Word length of the module’s optional
Reference Compensation data.
0 0 to 7
Analog Output Data
Reference
Starting offset for the module’s optional
Reference Compensation data.
user selectable
Line Frequency Specifies the line frequency. The module
uses this data to control the sampling rate.
60 Hz 50 Hz, 60 Hz
Suppress Open
Thermocouple
Determines whether or not the module will
suppress Open Thermocouple diagnostics
on the input data.
No Yes, No
Channel Active Specifies if the channel should return data
and alarms. If a channel is “inactive”
space is still allocated for it.
Active Inactive (off)
Active (on)
Engineering Units Specifies how the module will report input
values
1/10 degrees C Millivolts, 1/10 degrees C,
1/10 degrees F
Thermocouple Type The type of thermocouple present on each
channel.
J None, J, K, T, S, R
Range For millivolt inputs only, the range for each
channel in millivolts.
625 19.53, 39.06, 78.125, 156.25,
312.5, 625.
R J Type Specifies how or whether the channel will
perform Cold Junction compensation.
Local Local, Remote, Fixed, None
Alarm Low The low alarm limit for the channel, in
engineering units.
–2000 –32,768 to +32,767
Alarm High The high alarm limit for the channel, in
engineering units.
8000 –32,768 to +32,767
Reference Junction
Value
Specifies a reference value if Fixed RJ
Type has been configured.
250 –32,768 to +32,767
Correction Factor Specifies optional amount to be added to
compensated and linearized input value
when a Conversion Type in degrees has
been configured.
0 –32,768 to +32,767
Channel Default Input Specifies analog input returned upon error
(including open circuit errors).
0 +32,767
Cold Junction Default 250 +32,767
