Product Description

The Beckhoff EL7342 is a dual-channel EtherCAT terminal that is part of the EL series. This apparatus is designed to directly connect and regulate DC brush motors, which use physical contact between brushes and a commutator to enable current flow within the motor and produce motion. The maximum output current of the EL7342 is 3.5A per channel. This indicates the highest electrical current that can be safely supplied to the DC motor that is attached, which affects the torque and speed capabilities of the motor. The terminal's capacity to tolerate a supply voltage range of 8 to 48V DC shows how versatile it is to a variety of power sources. The EL7342's ability to connect to a motor directly is one of its noteworthy features. This streamlines the system design, gets rid of the requirement for middle-tier parts like motor drivers, and could even save money. The terminal enables precise control over the motor's functioning by directly interacting with it. The system's adaptability and efficiency are increased by the dual-channel arrangement, which concurrently controls two separate DC brush motors.

A number of features included in the EL7342 are intended to maximize both performance and safety. It has inputs for each channel's encoder and end position sensor. By detecting the motor's extreme locations, the end position sensor guards against any overtravel damage. Accurate control and monitoring are made possible by the encoder, which gives feedback on the motor's speed and shaft position. The gadget and the linked motor are protected from electrical faults by the output stage of the terminal's protection against overload and short-circuit circumstances. A 32 kHz PWM (Pulse Width Modulation) clock frequency with a 180° phase shift for each channel is supported by the EL7342. Through the manipulation of electrical pulse width, this method effectively and precisely controls the motor's speed.

To provide precise measurement and control of these parameters, the EL7342 further provides a resolution of up to 10 bits for current and 16 bits for speed. With a typical current demand of 5 mA, the encoder input signal from the terminal functions in the 5 to 24V DC range. It enables high-precision position detection by handling an input frequency of up to 400,000 increments per second with a 4-fold evaluation. For applications requiring more performance, the ZB8610 fan cartridge may be added to the EL7342. By increasing the terminal's cooling capacity, this accessory allows for an output current increase of up to 6.5A per channel. Higher-speed operations or more potent motors may be controlled thanks to this increase in current capabilities. Wake Industrial gives clients peace of mind and confidence in their investment by giving a one-year guarantee, demonstrating their commitment to the EL7342's quality and dependability.
