Introduction
16-channel digital input 24 VDC, 3.0 ms
The EP1809-0042 EtherCAT Box with digital inputs acquires the binary control signals from the process level and transmits them, in an electrically isolated form, to the controller. The state of the signals is indicated by light emitting diodes. The signals are connected via M12 screw type connectors.
The sensors are supplied from the box supply voltage US. The auxiliary voltage UP is not used in the input module, but may be connected in order to be relayed downstream.
The EP1809-0042 is interference-free. You can use the EP1809-0042 instead of an interference-free standard terminal in accordance with the following chapter of the TwinSAFE Application Guide:
- "All-pole disconnection of a potential group with downstream interference-free standard terminals (Category 4, PL e)"
- "Single-pole disconnection of a potential group with downstream interference-free standard terminals with fault exclusion (Category 4, PL e)"
- „EL2911 potential group with interference-free standard terminals (Category 4, PL e)"
