Technology
The EL2502 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.
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.
For EL2502 operating principle see Basic function principles.
