Pantech Instruments manufactures Logic Signal Computation Module, model 834. Pantech Instruments is the manufacturer and exporters of Process Control Instruments. Logic Signal Computation Module is designed to accept two or more signals [maximum 10 numbers] at the input terminal strips. The output can be a logical function [HI / LO / Average / Specials] of the inputs. These input and output signals of the Logic Signal Computation Module can be of Linear Current [4-20 mA DC like] or Linear Voltages only. This output signal hence obtained can be isolated or non-isolated. Low drift precession components are used in the Logic Signal Computation Module for long term accuracy of the instruments. All instruments undergo a burn-in for better reliability. The Logic Signal Computation Module is available in different formats and sizes.
