Introduction
Electronic overcurrent protection terminal
EL9221-xxxx | Single-channel overcurrent protection terminal with standard functionalities
The EL9221-xxxx electronic overcurrent protection terminal is a 24 V DC EtherCAT Terminal with electronic protection function. The single-channel EL9221-xxxx reliably switches off 24 V DC overcurrents. The nominal current can be set in 1 A steps up to 10 A, either via TwinCAT or via a mechanical pushbutton on the overcurrent protection terminal. In addition, there are further versions of the terminal with a fixed nominal current. The protected output can be routed out via a terminal contact or directly to adjacent terminals without wiring via the power contact.
The EL9221-xxxx has standard functionalities, i.e. the following setting options and process data are available:
- Settings: Nominal current, LED button programming function
- Process data: Enabled, tripped, prewarning, cool-down lock, hardware protection
EL9222-xxxx | Two-channel overcurrent protection terminal with standard functionalities
The EL9222-xxxx electronic overcurrent protection terminal is a 24 V DC EtherCAT Terminal with electronic protection function. The 2-channel EL9222-xxxx reliably switches off 24 V DC overcurrents. The nominal current can be set in 1 A steps up to ∑ 10 A, either via TwinCAT or via a mechanical pushbutton on the overcurrent protection terminal. In addition, there are further versions of the terminal with a fixed nominal current for each channel. The protected output 1 can be routed out via a terminal contact or directly to adjacent terminals without wiring via the power contact.

EL9227-xxxx | Two-channel overcurrent protection terminal with extended functionalities
The EL9227-xxxx electronic overcurrent protection terminal is a 24 V DC EtherCAT Terminal with electronic protection function. The 2-channel EL9227-xxxx reliably switches off 24 V DC overcurrents. The nominal current can be set in 1 A steps up to ∑ 10 A, either via TwinCAT or via a mechanical pushbutton on the overcurrent protection terminal. In addition, there are further versions of the terminal with a fixed nominal current for each channel. The protected output 1 can be routed out via a terminal contact or directly to adjacent terminals without wiring via the power contact.
The EL9227-xxxx has extended functionalities, i.e. it is additionally able to handle monitoring applications, since numerous process data are available, e.g.:
enabled, tripped, short circuit, overload, overvoltage, undervoltage, current level warning, cool down lock, hardware protection, switched off by pushbutton, DI, EtherCAT, load, instantaneous current, input voltage and output voltage.
Furthermore, it can be used flexibly, since numerous settings are available individually, e.g.:
nominal current, characteristics, manual characteristics, prewarning, start behavior, input behavior, overvoltage behavior, undervoltage level, reverse feed behavior, LED button programming function.
All EL9227 terminals are equipped with protection against reverse polarity and reverse feed
