Chapter 1. INTRODUCION 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).
Chapter 1. INTRODUCION Analog value is a sequentially changing value such as voltage, current, temperature, speed, pressure, flux, etc. Temperature, for example, is sequentially changing according to the time. Because this temperature is not inputted on the PLC directly, the same analog value of DC voltage (0 to 10V) or current (4 to 20mA) in accordance with the temperature should be input on the PLC through transducer.

Chapter 1. INTRODUCION Digital/analog conversion module allows digital value of the CPU to be converted into an analog value and to be output externally. Digital input value of 0 leads to analog output value of 0V and 4000 leads to 10V. Digital input value of 1 is equal to 2.5mV. 2) Voltage output - G4F-DA3V/G4F-DA2V/G6F-DA2V 5 ㎷...
