Burkert Universal Controller Temperature/Ratio Control Panel Mounting 24VDC Terminal - 8611 210206

This Burkert 8611 universal controller has a compact design and is used for temperature and ratio control. The controller is designed for mounting in a panel. The operation of this controller requires a power supply of 24 V DC. The process value feedback can be directly supplied to the universal controller through a 4-20 mA or 0-10 V signal, RTD signal or 2x frequency-NPN/PNP signal, an RTD signal or 2x frequency-NPN/PNP signal. The controller uses a Pt100 sensor to measure temperature. The controller has different outputs, including 1 x PWM and 2 x PTM, which can use 4-20 mA and 0-10 V signals. The controller has terminal block to connect to other devices. This controller is IP65 certified for protection against dust and water ingress.

Pros:

• Control proportional, process and motor valves
• Bürkert proportional valve and flow meter parameters are memorized
• The controller uses a Pt100 sensor to measure temperature
• Ratio control function
• Continuous, 2-point, 3-point and On/Off control

Cons:

• The controller can only be powered with 24 V DC

Series:

The Bürkert type 8611 is a compact controller suitable for use in small control system applications. The Bürkert type 8611 works with Bürkert proportional valves and sensors, as well as other control valves that use standard signals like 4-20 mA, 0-10V, or PWM-output. It has been tested to ensure compatibility. The PI process controller can receive feedback about the process through three analog inputs: standard signal (4-20 mA / 0-10 V), frequency, or RTD signal. It also lets you set the process switching points using a 4-20 mA or 0-10V signal or the keypad. It is also possible to set a cascade structure for temperature-specific control that considers both temperature and flow as inputs. The 8611 controller can control different things in liquids and gases using proportional control. This controller provides continuous, 2-point, 3-point, and On/Off control options, along with a ratio control function, and the capability to control proportional, process, and motor valves. The controller can save information about Bürkert proportional valves and flow meters. The Bürkert 8611 can not only be used for proportional control, but can also be used to control a process parameter with the integrated PI controller. Based on a setpoint value and an input process value, it tries to determine the optimal valve position to reach the setpoint value.
