Data Acquisition Terminal for Quality Control Stations

Product Specifications

Technical details and manufacturing context for Data Acquisition Terminal

Definition

The Data Acquisition Terminal is a critical component of a Quality Control Station, responsible for interfacing with sensors (e.g., temperature, pressure, dimension gauges) to digitize analog signals, perform initial data processing (like filtering or unit conversion), and relay this information to central monitoring or analysis systems. It ensures accurate, real-time capture of production parameters for quality assessment and process control. The terminal typically features 8 to 32 input channels, accepting analog signals such as 4-20 mA, 0-10 V, RTD, and thermocouple inputs, as well as digital signals. Sampling rates range from 10 to 1000 Hz per channel, with a measurement accuracy of ±0.1% of full scale. It operates on a 24 V DC supply (±10%), consuming 5 to 15 W depending on configuration. The device is designed for industrial environments, with an operating temperature range of -20 to 60 °C, storage from -40 to 85 °C, and non-condensing humidity of 10 to 90% RH. Ingress protection ratings from IP54 to IP65 (per IEC 60529) are available. Communication interfaces include RS-232, RS-485, and Ethernet, with optional wireless capabilities. A TFT LCD display (5.7 to 12.1 inches) with optional touchscreen is provided. The terminal is available in panel-mount or portable configurations, with dimensions ranging from 200×150×50 mm to 400×300×100 mm and weight from 2 to 5 kg. Typical materials include a printed circuit board, electronic components, and a plastic or metal enclosure. For specific models, verify all parameters with the manufacturer or supplier.

Working Principle

The terminal receives analog or digital signals from connected sensors via input channels, such as analog-to-digital converters. It samples these signals at a defined rate, converts them into digital values using embedded processors, applies any configured calibration or scaling, and then transmits the formatted data to a supervisory system (like a PLC, SCADA, or database) through communication interfaces (e.g., Ethernet, RS-485, or wireless protocols).

Frequently Asked Questions

What types of sensors can be connected to the Data Acquisition Terminal?

The terminal accepts analog signals such as 4-20 mA, 0-10 V, RTD, and thermocouple inputs, as well as digital signals. The exact compatibility depends on the model and configuration; consult the manufacturer for specific sensor types.

What is the maximum sampling rate of the terminal?

The sampling rate ranges from 10 to 1000 Hz per channel, depending on the model and number of active channels. Higher rates may reduce the number of channels that can be sampled simultaneously.

Can the terminal be used in harsh industrial environments?

Yes, it is designed for industrial use with an operating temperature range of -20 to 60 °C, storage from -40 to 85 °C, and non-condensing humidity of 10 to 90% RH. Ingress protection ratings from IP54 to IP65 (per IEC 60529) are available, but the specific rating must be verified for the chosen model.

What communication interfaces are available?

Standard interfaces include RS-232, RS-485, and Ethernet. Optional wireless communication may be available. The availability of these interfaces depends on the specific model and configuration; confirm with the manufacturer.
