Product Description:

The ES4008 EtherCAT terminal is a module designed for industrial automation, featuring an eight-channel analog output. The Beckhoff system is designed to generate high-performance signals and facilitate efficient communication.

The ES4008 EtherCAT terminal can handle signals ranging from 0 to 10 V and has 8 analog outputs. It runs at a resolution of 12 bits and takes about 400 µs to convert. The terminal's capacity to sustain loads that are greater than 5 kilovolts and its design that prevents short circuits both contribute to its excellent reliability. The average amount of milliamperes that it draws from the E-bus is 100, and the amount that it draws from the power connections is 40. In order to guarantee the security of the system, the device separates the E-bus and signal voltages by a distance of 500 volts. This is because it is able to work with distributed clocks that have a precision of less than 1 µs, which allows it to improve synchronization in applications that are time-critical.

When compared to the final value, the ES4008 EtherCAT terminal's output error is less than 0.1 percent. The process picture has a bit width of 8 × 16-bit analog output, which allows for accurate and unambiguous data handling. This terminal is well-suited for complex automation tasks due to its extensive set of additional capabilities. An optional watchdog is one of the special features; it allows the user to set their own output values and can synchronize and ramp them up or down. Because of these characteristics, the terminal can be used for a wide variety of automation tasks. Because of its sophisticated features and small size, the module is compatible with a wide range of control systems.
