Introduction
1 channel pulse train output terminal
The EL2521-xxxx output terminals output a pulse sequence to downstream receiving devices such as motor output stages. For this purpose, it has two output channels A and B on the hardware side, the relationship between which can be set, e.g. as a direction-dependent encoder characteristic. The EL2521-xxxx supports two functions
- Pulse output with variable frequency
- Travel mode: pulse output with variable frequency and number of pulses
The EtherCAT Terminals indicate their signal state by means of light emitting diodes. The LEDs are clocked with the outputs and each displays an active output.
The EL2521-xxxx is available in the following variants
- The EL2521 has two RS422 outputs and two digital inputs.
- In the EL2521-0024 the two output channels are designed as potential-free FET switches and can be supplied externally.
- The EL2521-0124 also has potential-free FET switches like the -0024, but is also equipped with a latch input and a 24 V output.
- In the EL2521-0025 the two output channels are negative-switching, potential-free FET switches and can also be supplied externally. Note the logic reversal in the control.
Note: pulse width modulation is not possible with the EL2521-xxxx.
