LS G41-D22A DC input 16 point module (current sink/source type) Industrial PLC

LS Power Generation G4I-D22A is a digital input module, and G4F - DA1A is an analog output module. The following compares their technical parameters from different aspects:

Function and Use

G4I-D22A: Mainly used to collect digital signals from external devices, such as the on/off status of switches, high and low level signals of sensors, etc., and input these digital signals into the PLC system so that the PLC can perform logical judgment and control.

G4F-DA1A: Mainly used to convert digital signals inside the PLC into analog signal outputs. Common analog signals such as voltage or current signals are used to control some equipment that requires continuous adjustment, such as control valves, frequency converters, etc.

Electrical Characteristics

Number of Input/Output Points

G4I-D22A: Has 16 input points and can collect 16 digital signals at the same time.

G4F-DA1A: Has 2 output channels and can output 2 analog signals.

Signal type

G4I-D22A: The input signal type is a digital signal, supporting DC 12V or 24V input voltage, and can be a current sink or source input mode.

G4F-DA1A: The output signal type is an analog signal, supporting output signal ranges including DC ±10V and DC 4 - 20mA.

Power supply requirements

G4I-D22A: Its working power supply is usually provided by the PLC system. The specific power supply specifications need to be combined with the power supply configuration of the entire PLC system, and generally adapt to the commonly used power supply voltage of the PLC.

G4F-DA1A: The working voltage is DC 24V, and a stable 24V DC power supply is required to ensure the normal operation of the module.

Performance indicators

Accuracy and resolution

G4I-D22A: The digital input module mainly focuses on the high and low level identification of the signal. Generally, there is no concept of accuracy and resolution. It only requires the ability to accurately distinguish the logical state of the input signal (high level or low level).

G4F-DA1A: The accuracy and resolution of analog output modules are important indicators. Accuracy reflects the closeness of the output signal to the theoretical value, while resolution indicates the minimum signal change that can be output. However, the specific accuracy and resolution values need to refer to the detailed product manual.

Response time

G4I-D22A: Response time refers to the time interval from the change of the external signal to the module reflecting the change in the PLC system. It is usually short to ensure that the signal change can be collected in time.

G4F-DA1A: Response time refers to the time from the PLC sending a digital signal to the module outputting the corresponding analog signal reaching a stable value. It also needs to be within a reasonable range to meet the real-time requirements of the control device.

Mechanical characteristics

The two may also differ in mechanical characteristics such as size and weight. These characteristics will affect the installation and layout of the module in the control cabinet. The specific mechanical size and weight need to refer to the physical specifications of the product.
