Product Description:

The CLC-PI.1 is a high-performance motion controller by Bosch Rexroth Indramat. It is used in industrial control systems and operates in a stable manner. It has several communication and power interfaces to enable precise control. It is part of the CLC Motion Controllers family.

The CLC-PI.1 is designed for demanding automation requirements. It runs at a nominal voltage of 24 V DC and has a supply range of 18 V to 32 V. Under normal operating settings it draws 100 mA of current. The input resistance ranges between 3 and 7 kilo Ohms with a sensitivity of ~3 V. The RS-422 and RS-485 interfaces are symmetrical. Both support a cable length of up to 1200 meters and a baud rate of 9600. RS-422 input resistance is 4 kilo Ohms while RS-485 is 12 kilo Ohms. Both provide ~200 mV input sensitivity. The maximum route attenuation supported is 12.5 decibels. The controller has two digital input levels such as logic high from 14 V to 32 V and logic low from 0 V to 3 V. The maximum output current is 100 mA. It features three serial interfaces.

The Bosch Rexroth Indramat CLC-PI.1 can function in temperatures ranging from +5 to +45 degrees C. The temperature range for storage and transportation is -30 degrees C to +85 degrees C. It can endure maximum relative humidity of 95% and absolute humidity of 25 g/m^3. The Bosch controller has a fiber optic interface with a transmitter power of -7.5 dBm to -3.5 dBm. Its receiver can withstand input power ranging from -20 dBm to -5 dBm and operates on a wavelength of 640-675 nm. The service life at 25 degrees C is up to 4 years. It can be stored at 25 degrees C for three years and stays functioning.

Frequently Asked Questions about CLC-P1.1:

Q: What is the function of the TVW output in the CLC-PI.1?

A: The TVW output with 100 mA current capacity supports status signaling. It enables communication with connected devices or indicators during operation.

Q: How does the fiber optic interface improve signal integrity in CLC-PI.1?

A: The fiber optic interface in CLC-PI.1 minimizes electromagnetic interference. It ensures long-distance data transmission with high reliability.

Q: Why is ~3 V input sensitivity important in the RS-232 port?

A: This sensitivity allows accurate signal detection in environments with voltage fluctuations. It ensures data integrity over the entire 15-meter cable range.

Q: What advantage does the symmetric RS-422 interface provide in CLC-PI.1?

A: Symmetric transmission reduces noise and enhances data stability. This is critical in electrically noisy industrial environments.

Q: Why is the 640-675 nm wavelength range used in fiber transmission?

A: The 640-675 nm wavelength range is used in fiber transmission because it minimizes signal loss. It offers optimal performance and efficiency in optical fiber communication.
