Product Description:

The ES5151 EtherCAT terminal is designed for precision encoder applications and it is developed by Beckhoff for accurate motion and signal control. It is small and weighs approximately 50 grams. It can be integrated easily into EtherCAT I/O systems.

The ES5151 EtherCAT terminal supports one encoder input channel and the connection uses A, B, and C signals at 24 V DC. It is a single-ended connection type defined by EN 61131-2 type 1. An additional input is included for latch or gate functionality. This input operates at 24 V DC for trigger-based control. The terminal has a counter that is 16 or 32-bit switchable. This allows flexibility for different counting applications. The quadrature decoder supports 4-fold signal evaluation. This decoding method increases precision in directional tracking. The maximum limit frequency is 100 kHz input rate. The terminal supports up to 400,000 increments per second. This high-speed evaluation provides fast and accurate feedback. The resolution reaches 1/256 bit using microincrement processing. This resolution is perfect for detailed motion or position control. The terminal also provides advanced attributes for flexible applications. These include edge timestamping and microincrement support. Other attributes are frequency measurement and gate functions.

The ES5151 EtherCAT terminal delivers accurate signal analysis and it is used in systems that demand high-speed encoder feedback. The Beckhoff ES EtherCAT terminal supports robust motion control. The terminal supports distributed clocks for synchronization accuracy. These clocks allow time-aligned data handling in EtherCAT networks. The power contact current consumption is typically 100 mA plus load. The e-bus draws around 130 mA during operation. It fits well in automated processes that require exact positional data. This terminal improves performance and accuracy in automation networks.
