The LX3V-4TC analog block amplifies the signal from four thermocouple sensors (Type K or J) andconverts the data into 16 bit reading''s stored in the main unit. Both centigrade (°C) and Fahrenheit(°F) can be read. Reading resolution is 0.4°C/0.72°F of Type K and 0.3°C/0.54°F of Type J. The LX3V-4TC can connected to the LX3V series Programmable Controllers (PLC). All data transfers and parameter settings are adjusted via software control of the LX3V-4TC; by use of the TO/FROM applied instructions in the PLC.
