Technology

The EL2502-0010 output terminal modulates the pulse width of a binary 24 V signal, i.e. it modifies the mark-to-space ratio. The output frequency is configurable for each channel.
Thanks to the implemented distributed clock functionality the terminal is able to change its state via the transferred timestamp (PWM on/off). Two modes are available (DC Immediately = true / false), which means that the current PWM cycle can either be aborted directly by the timestamp, or it can run for the full length beyond the timestamp
The peripheral side of the electronics is electrically isolated from the internal E-bus, and therefore also from the fieldbus.
The process data resolution of 16 bit is converted to the hardware resolution of 10 bit inside the terminal.
