Product Description:

The Bosch Rexroth S20-AI-4-I analog input module is designed to accurately analyze current signals in modern industrial automation systems. The module comes with four differential analog inputs with the capability to interpret standard industrial current signals of 0 to 20 mA and 4 to 20 mA. It is compatible with a large number of industrial sensors, transmitters, and actuators. It has a 16-bit resolution, making it highly precise for maintaining true signal integrity, thus suitable for precision-sensitive applications like process monitoring and control.

The S20-AI-4-I is designed to work on a 24 VDC power supply, and it is designed with galvanic isolation of up to 300 V RMS between the input channels and an internal bus or power system. This isolation protects against electrical noise, grounding loops, and other interferences, so that reliable data acquisition can be achieved within electrically harsh environments. The module is also very energy efficient as it uses very low power of only 1.2 watts to support the smart industrial systems.

It is highly durable and can withstand tough environments with a broad operating temperature range of -20 degrees Celsius to 60 degrees Celsius and a storage range of -40 to 85 degrees Celsius. Its small footprint (120 x 50 x 70 mm) and DIN rail help it to be easily mounted in a standard control panel, thus making it easy to use. It is CE and UL certified, and, therefore, complies with worldwide safety and compliance requirements. All in all, the S20-AI-4-I is a smart and effective analog input device, offering reliable, accurate, and interference-resistant analog input functionalities that make it beneficial for engineers who are involved in manufacturing, energy management, or process control fields.
