Sutron Corporation 8310 & 7310 Users Manual 8800-1125Rev. 2.7 (BETA) 4/16/2014 pg. 91
When multiple DIO modules are connected to the 8310, use this property to select
which DIO module was used when connecting the mux Enable and Clock lines.
EnableChannel
The DIO channel to assert to enable the mux.
ClockChannel
The DIO channel to pulse to select (i.e., “clock-in”), a mux channel.
SettlingTimeMS
The time in milliseconds to wait after clocking-in a channel.
SwitchedPwr
SwitchedPwr has the settings of none, SW-5, SW-12 and DigOut. If the setting is something
other than “none” the system will request a warmup time. SW-5 and SW-12 refer to the
Switched power connections on the C terminal strip. If DigOut is selected, you must specify one
of the digital outputs.
Processing
Slope-offset
A user entered Slope and Offset are used to scale the input value by the following equation:
Result=Slope*input+Offset
Poly
User entered coefficients are used to scale the input value by the following equation:
Result=K0+K1*input+K2*input
2
+K3*input
3
+K4*input
4
+K5*input

Steinhart-Hart
The Steinhart-Hart equation models the resistance of a device at different temperatures:
T = 1/(a + b*ln(r) +c*(ln(r)^3)) - 273.15
where r is the input resistance in ohms,
T is temperature in deg C
A, B, and C are coefficients which vary depending on the type and model of the thermistor and
the range of interest.
Steinhart-Hart coefficients are available from most thermistor manufacturers. Below is a table
of Steinhart-hart coefficients for some commonly used thermistors.
