Chapter 1 Introduction
1-1
The G3F-AD3A, G4F-AD3A, and G6F-AD2A modules are analog-to -digital conversion
modules for use with the GLOFA PLC GM1/2/3/4/6 series and MASTER-K PLC
K200S/300S/1000S series. The G3F-AD3A is used with GM1/2/3 series and K1000S
series, G4F-AD3A is used with GM4 series and K300S series, and G6F-AD2A is used
with GM6 series and K200S series. (Hereafter the G3F-AD3A, G4F-AD3A, and G6F-
AD2A modules are called as the A/D conversion module)
The A/D conversion module is to convert an analog input sig nal (voltage or current) from
external devices into a 12-bit signed binary digital value.
1.1 Features
1) Multi-channel analog to digital conversion is possible with a single A/D module.
- G6F-AD2A : 4 channels
- G4F-AD3A and G3F-AD3A : 8 channels
2) The select of voltage input or current input is possible by channel of A/D module.
3) The unlimited number of A/D modules can be mounted on a base board.
The maximum number of A/D modules depends on the power capacity of power supply
module.( In case of use to the G6F-AD2A with G6F-DA2V and G6F-DA2I, it is depends
on the power capacity of the GM6-PAFB)
