Chapter 1. INTRODUCTION
The G3F-DA3V/G3F-DA3I, G4F-DA3V/G4F-DA3I, the G4F-DA2V/G4F-DA2I and G6F-DA2V/G6F-DA2I are
digital/analog conversion modules for use with the GLOFA PLC GM1/2/3/4/6 series CPU module and the
MASTER-K200S/300S/1000S series CPU module. (Hereafter the G3F-DA3V/G3F-DA3I, G4F-DA3V/G4F-DA3I,
G4F-DA2V/G4F-DA2I and G6F-DA2V/G6F-DA2I are called the D/A conversion module)
The D/A conversion module is to convert a 16-bit, signed BIN digital value into an analog output signal (voltage or
current).
1.1 Features
1) Allows digital to analog conversion for 8 channels/4 channels per a module.
G3F-DA3V: 1 module can be performed for D/A conversion (voltage output) of 8 channels.
G4F-DA3V: 1 module can be performed for D/A conversion (voltage output) of 8 channels.
G4F-DA2V: 1 module can be performed for D/A conversion (voltage output) of 4 channels.
G6F-DA2V: 1 module can be performed for D/A conversion (voltage output) of 4 channels.
G3F-DA3I: 1 module can be performed for D/A conversion (current output) of 8 channels.
G4F-DA3I: 1 module can be performed for D/A conversion (current output) of 8 channels.
G4F-DA2I: 1 module can be performed for D/A conversion (current output) of 4 channels.
G6F-DA2I: 1 module can be performed for D/A conversion (current output) of 4 channels.
2) The number of the G3F-DA3V/G4F-DA3V/G4F-DA2V/G6F-DA2V and G3F-DA3I/G4F-DA3I/G4F-
DA2I/G6F-DA2I used on a base unit is limitless.
But the number of module is limited by capacity of the power supply module.
