### 4. Functionality

The EPS‑2032 functions as a sourcing‑type digital output module within an EtherCAT slave system. Each of its 32 channels can source current to external loads such as relays, solenoids, or indicator lamps. The module interfaces with the EtherCAT network through the EPS‑6000 bus coupler, which manages communication between the EtherCAT master and the EPS peripheral modules.

Operation Principle:
- The EtherCAT master sends output commands via the EPS‑6000 bus coupler.
- The EPS‑2032 receives these commands and drives the corresponding output channels.
- Each channel sources current from the EVCC supply to the connected load.
- The module’s internal diagnostics monitor power, communication, and watchdog status, reporting any anomalies to the master.

Typical Applications:
- Industrial automation and process control
- Machine tool control and robotics
- Packaging and assembly line systems
- Distributed I/O in smart manufacturing environments
- PLC‑based digital output expansion

Compatibility:
- Fully compatible with ADLINK’s EPS‑9905 chassis and EPS‑6000 EtherCAT bus coupler.
- Operates with ADLINK Talos EtherCAT master controllers and third‑party EtherCAT masters supporting ESI import.
- Configurable via ADLINK LinkMasterPro™ software for ESI generation and system diagnostics.
