This manual is a learning and reference guide for the G3F-TC4A , G4F-TC2A and G6F-TC2A. The G3F-TC4A is a
thermocouple input module used with the CPU of GLOFA GM1/2/3 series and MASTER-K 1000S series .The
G4F-TC2A is used with the CPU of GM4 series and K300S series The G6F-TC2A is used with the CPU of GM6
series and K200S series. Hereafter, the three modules called thermocouple input module. The thermocouple input
module converts a temperature input by a thermocouple (Type K, J, E, T, B, R or S) into a signed 16-bit digital
binary data and outputs it.

▶ The thermocouple input module has following features.
1) With direct connection of one of seven types of thermocouple to the thermocouple input module, a
temperature data (°C) can be converted into a digital value to be processed in the PLC
2) The temperature data (°C) input can be processed to one digit after the point as a digital value.
3) 16 point (G3F-TC4A) or 4-point (G4F-TC2A/G6F-TC2A) of thermocouple can be connected to one module.
4) Disconnection and Out-of-range detection function for every channel are included
5) The thermocouples in accordance with five specifications (KS, JIS, ANSI, DIN, BS) are available.
6) The temperature sensor loaded onto terminal block performs automatic reference junction compensation.
