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.
