SC-MATHSCON
Programmable Mathematics Unit
3-Port Isolation to 1000Vdc
High Accuracy, Low Cost
1 Universal & 1 Voltage/Current Input
User Configurable Maths Function
Two Isolated Inputs and One Isolated Output
Ultra Compact, only 17.5mm Wide
The SC-MATHSCON Isolating Signal
Converter can be user-configured to carry
out a wide range of mathematical functions
on two isolated input channels. One input
is a universal current, voltage,
thermocouple or RTD input, and the other
can be either voltage or current.
Each channel can be multiplied by a factor
or linearised and then any of the following
functions can be performed on those input
channels.
Addition Output = A + B
Subtraction Output = A - B
Multiplication Output = A x B
Division Output = A / B
Square Root Output = v(A-B)
High Signal Select
Low Signal Select
Average of the two signals
The unit provides an isolated, scaleable
current or voltage output corresponding to
the result of the required function.
The power supply requirement is 16 to 32V
dc.
