Input Type (V5017)
Input Type specifies the temperature or voltage input device being used. This parameter is used in
conjunction with the module jumper settings described on page 2.2. RTDs, Voltage Inputs or
Thermocouples cannot be mixed on the same module. Any combination of thermocouple types K, J, E,
and N may be used. Also types R, S, B, and C may be used on the same module. The Type T
thermocouple and all the voltage input ranges cannot be mixed on the module. Input Type is read by the
controller when bit 0 of the Mode Word is set.
Thermocouple Input Types: 0=J, 1=E, 2=K, 7=N or 3=R, 4=S, 6=B, 20=C or 5=T
Voltage Input Types: 26=0-5V or 27=±5V or 29=0-156.25mV or 30=±156.25mV
Input Type codes for 100S platinum RTDs are 8=European and 9=American. The Input Type code for a
1000S European curve platinum RTD is 10. All RTDs used on the same module must be the same
resistance range (you can mix types 8 and 9 since they are both 100S). European 100S and 1000S
RTDs are sometimes referred to as Pt100 and Pt1000. They both have an alpha value of 4 = .003850.
American RTDs are sometimes referred to as jPt100 and have an alpha value of 4 = .003916. The
alpha value is the mean temperature coefficient of the Resistance Temperature Device (RTD) and is
normally .003850. Both 10S and 25S copper RTDs are supported via Input Type codes 11 and 12
respectively.
RTD Input Types: 8=Pt100,9=jPt100 or 10=Pt1000 or 11=CU-10S or 12=CU-25S
Note
To prevent an invalid combination of Input Types, power cycle the controller after changing an
Input Type. Valid combinations are: K,E,J,N or R,S,B,C or Pt100,jPt100. All other types are
unique.
