Introduction
16-channel digital input with diagnostics
The EP1839-0042 EtherCAT Box with 16 digital inputs acquires binary control signals from the process level and transfers them, with electrical isolation, to the controller. The signal state is displayed by LEDs; the signals are connected via screwable M12 connectors. A wire break detection can be enabled/disabled for each channel. The signal input filters are individually adjustable.
Each M12 socket has an independent 24 V DC/0.5 A short-circuit proof sensor supply from US for the two connected sensors. This is monitored and any errors are reported to the controller via a diagnosis. Module-related undervoltage detection of the input voltage takes place.
The peripheral voltage UP is not used in the input module, but it can optionally be connected for forwarding and is fed through to the next device. Due to the adjustable input filter and the comprehensive supply and diagnostics logic, the EP1839-0042 is particularly suitable for applications in which a high system availability and thus fast fault-finding and troubleshooting are required.
The EP1839-0042 has M12 D-coded EtherCAT connections and 7/8" connectors for the power supply.
Special features:
- adjustable wire break detection per sensor
- Undervoltage detection of the sensor supply US
- short-circuit proof sensor supply US 0.5 A per M12 socket
- parameterizable input filters per signal
The EP1839-0042 is interference-free. You can use the EP1839-0042 instead of an interference-free standard terminal in accordance with the following chapters 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)"
