### 4. Functionality

The EPS‑1132 functions as a 32‑channel digital input slave module within an EtherCAT network. Each channel detects the logical state of external devices such as sensors, switches, or proximity detectors using a sinking input configuration. The module interfaces with the EtherCAT bus via the EPS‑6000 bus coupler, transmitting input data to the EtherCAT master controller in real time.

Typical Use Cases:
- Industrial automation and process control
- Machine tool monitoring and safety interlocks
- Factory I/O expansion for PLC or motion controllers
- Distributed digital input acquisition in EtherCAT networks

Operation Principle:
Each input channel senses voltage levels from external field devices. When the input voltage exceeds the ON‑state threshold (10 V – 30 V), the channel registers a logical “1.” When below 5 V, it registers a logical “0.” The module’s internal circuitry provides current limiting and reverse‑voltage protection to safeguard against wiring errors.

Compatibility:
- Fully compatible with ADLINK’s EPS‑9905 chassis and EPS‑6000 EtherCAT bus coupler.
- Operates with ADLINK’s Talos EtherCAT master controllers or any third‑party EtherCAT master supporting standard ESI files.
- Configurable and monitored via LinkMasterPro™ software.
