【英文介绍】

The Allen-Bradley 1756-HYD02 is a module that connects to the 1756 ControlLogix controller and is commonly used for precise control and positioning of hydraulic cylinders. It can be connected to a linear displacement sensor (LDT) for feedback, or to a proportional or servo valve to control the hydraulic shaft, up to two axes can be controlled by one module. The LDT will provide an analog command reference for the valve. This is to ensure that the actuator or cylinder follows the profile. Once feedback is received, the 1756-HYD02 module closes the high speed position loop with the help of a hydraulic system connected to it. It will then produce a +/-10V analog output speed command. The servo loop type is proportional, Integral, and Differential (PID) with feedforward and directional scaling functions. The 1756-HYD02 has a gain resolution of 32-bit floating point and an absolute position range of 230,000 LDT counts. It also has optional speeds from 500 Hz to 4 KHZ. Current consumption is 700 mA for 5.1 volts DC and 2.5 ma for 24 volts DC. The heat dissipation is 18.77 BTU/ hour and the isolation voltage is 30 volts continuous from the user to the system. The 1756-HYD02 can be installed in any slot in the ControlLogix chassis. To install, you simply slide it into the available slot until it snaps into place. However, keying of the removable junction box (RTB) is recommended to prevent accidental connection of the wrong RTB to the module. Make sure to use a unique keying mode for each slot. For this 1756-HYD02 module, you can use a cage clamp or a spring clamp.

The 1756-HYD02 is a ControlLogix hydraulic servo module developed by Allen-Bradley and Rockwell Automation. This hardware is often used for precise positioning and control of hydraulic cylinders. It can be connected to a linear displacement sensor (LDT) for feedback, to a proportional or servo valve to control a hydraulic shaft, and to a hydraulic system to close a high-speed position ring. The hardware's specifications include up to 2 axes (for the number of axes available), proportional, Integral, and differential (PID), with feedforward and directional scaling (for servo loop types), and 32-bit floating point for gain resolution. The hardware also has an absolute position range of 230,000 LDT counts and a servo loop rate of 500 Hz to 4 kHz (optional).

The module location of this 1756-HYD02 is the 1756 ControlLogix chassis, which uses electronic module keying and has a maximum power consumption of 5.5 watts. Other specifications of the hardware include heat dissipation of 18.77 British thermal units (BTU) per hour, backplane current of 5.1 volts DC at 700 mah and 24 volts DC at 2.5 mah, and isolation voltage at 30 volts continuous voltage. Environmental specifications include maintaining operating temperatures between 0 and 60 degrees Celsius (32 to 140 degrees Fahrenheit), storage temperatures between -40 and 85 degrees Celsius (-40 to 185 degrees Fahrenheit), and relative humidity between 5% and 95% (non-condensing). Vibrations comply with IEC 60068-2-6 with A rating of 2g at 10-500 Hz, shocks comply with IEC 60068-2-27 with 30g (working) and 50g (non-working), and emissions comply with CISPR 11: Group 1, Class A.
