ABB TPSG4AI 1KHL015623R0004 Analog Input Module

ABB TPSG4AI 1KHL015623R0004 Analog Input Module Overview

Basic Information

Brand and Model: ABB product, model TPSG4AI 1KHL015623R0004, belongs to Analog Input Module.

Application Scenario: Used in industrial automation control systems (such as PLC, DCS systems), collect field analog signals (such as voltage, current, temperature, pressure, etc.), and convert them into digital signals for controller processing.

Functional Features

Signal acquisition type: Supports a variety of analog input signals, typically including:

DC voltage (such as 0-10V, ±10V)

DC current (such as 4-20mA, 0-20mA)

Thermal resistance (RTD, such as Pt100, Pt1000)

Thermocouple (TC, such as K, J, T type, etc.)

The specific supported type needs to be confirmed according to the module configuration (some models may only support specific signals).

Number of channels: usually 4 or 8 independent input channels ("4AI" in the model number may represent 4 analog inputs).

High-precision conversion: built-in high-resolution ADC (analog-to-digital converter), the resolution is usually 12 bits, 16 bits or higher, to ensure signal acquisition accuracy (such as ±0.1% FS error).

Electrical isolation: optoelectronic isolation or electromagnetic isolation is used between channels or between channels and the system to prevent external interference from affecting the control system, and provide overvoltage protection (such as ±30V input protection).

Signal processing function:

Linearization processing (such as thermocouple cold end compensation, thermal resistor temperature conversion).

Wire break detection (for current signals, it can detect whether the line is disconnected).

Over-limit alarm (trigger an alarm when the input signal exceeds the set threshold).

Status indication: equipped with LED indicators to display the module operation status (such as power, communication, channel failure, etc.).
