Internal Product Review
The EP1816-3008 is a Beckhoff EP digital input module with 16 digital inputs and Type 3 input characteristics per EN 61131-2. Integrated condition monitoring adds strong value through two 3-axis accelerometers in a 90° offset layout and 10-bit acceleration resolution. A 500 µs minimum cycle time makes this module a very capable choice for high-response EtherCAT installations.

Product Description:
The EP1816-3008 is a distributed I/O device produced by Beckhoff within the EP Digital Input Modules series. It mounts directly on the machine frame and connects to an EtherCAT network segment, where it provides 16 type 3 digital inputs for 24 V control circuits while also hosting two integrated 3-axis accelerometers oriented 90° to each other for vibration analysis. By combining signal acquisition and condition monitoring in one housing, the module reduces cabinet wiring and provides time-synchronized data to the main controller over the EtherCAT network.
The input stage is designed for a nominal bus voltage of 24 V DC, and each channel draws only 3 mA, keeping sensor loading low. Input transitions are conditioned by a filter of 10 µs, allowing fast-switching sensors to be captured without contact bounce appearing in the PLC process image. The minimum EtherCAT cycle time is 500 µs; at this rate, the device can refresh its process image during every network cycle. Internal sampling supports a transfer rate of up to 2.5 kHz, helping prevent input edges from being lost between frames. The digital front end follows EN 61131-2 type 3 requirements, which allow sensors with either PNP or push-pull outputs to be connected without additional adapters.
Galvanic isolation between the EtherCAT circuitry and the field side is rated at 500 V, protecting upstream hardware from wiring faults. Field wiring may extend up to 30 m per channel, enabling the module to remain close to actuators while the controller cabinet is located remotely. Up to 0.5 A of sensor power is available through the 25-pin D-sub signal connector, and all network traffic passes through two M8 A-coded sockets arranged for a daisy-chain topology. Acceleration data is delivered at 10-bit resolution. Undervoltage detection below 18 V triggers a diagnostic flag so the controller can react before the inputs misinterpret a low supply voltage.
