Analog input module for compact controllers, 8AI, U/I 12bit, Screw connections XBF-AD08A

Analog Input Module for LS Electric Controllers

This analog input module, designed for LS Electric compact controllers, expands the system's capabilities with 8 independent measurement channels. It enables acceptance of both current and voltage signals, making it a versatile solution in industrial automation applications. The XBF-AD08A module is ideal for precise reading of data from sensors and transducers, ensuring reliable operation in demanding conditions.

Characteristics and application

The XBF-AD08A module offers 12-bit resolution, which translates to high measurement accuracy. It supports a wide range of input signals: DC voltages 1-5V, 0-5V, 0-10V and currents 0-20mA and 4-20mA. Therefore, it can be successfully used in monitoring and control systems where processing signals from various sources is required. Screw terminals provide convenient and secure connection of wires. The module requires an external 24VDC power supply.

Advantages and benefits

• Versatility: Acceptance of current and voltage signals in one module eliminates the need to use multiple separate devices.
• High accuracy: 12-bit resolution ensures precise readings of data from sensors and transducers.
• Configuration flexibility: The ability to select measurement ranges allows you to adapt the module to specific application requirements.
• Signal filtering: Built-in filtering functions (digital filter) reduce interference and improve the stability of readings. The filtering time can be set in the range of 4–64,000 ms.
• Averaging functions: Various averaging methods (time average, count average, moving average) are available to further increase measurement accuracy.
• Diagnostics: The circuit break detection function (for 1–5 VDC and 4–20 mA DC signals) makes it easier to identify problems with sensors or wiring.
• Galvanic isolation: The use of optical isolation between the input terminals and the controller power supply provides protection against interference and damage.
• Wide operating temperature range: The module can operate at an ambient temperature of 0 to 55°C, allowing it to be used in various industrial environments.

Technical parameters and operating conditions

The XBF-AD08A module has been designed to operate in harsh industrial conditions. It meets standards regarding resistance to electromagnetic interference and vibrations. The storage temperature range is -25 to 70°C, and the relative humidity of the air during operation and storage is 5–95% (without condensation). The internal current consumption is 105mA at 5VDC power supply, and the external – 85mA at 24VDC power supply. The weight of the module is only 81g, which facilitates installation and integration with the control system. Resistance to square pulse interference with an amplitude of 1500VAC and electrostatic discharges up to 4kV (contact) is ensured.
