Beckhoff EL1252 Ethercat 2-Channel Digital Input Terminal

1.High Channel Density & Compact Design

As a 16-channel digital input module, the EL1252 integrates 16 independent input channels within a compact size of 100×100×32mm, with each channel occupying only about 6.25mm of space. It significantly saves DIN rail installation area, especially suitable for high-density I/O layout scenarios in automated control cabinets, solving the problem of excessive size of traditional multi-channel modules.

2.High-Speed Real-Time Signal Acquisition

Based on EtherCAT bus technology, the module has a data transmission cycle as low as 100μs and an input signal response time ≤1μs. It can capture rapidly changing digital signals in industrial sites (such as on-off signals of sensors in high-speed production lines) in real time, ensuring no delay in signal acquisition and providing accurate and timely on-site data support for the control system.

3.Industrial-Grade Anti-Interference & Reliability

Adopting photoelectric isolation technology (250V AC isolation voltage per channel), it effectively resists electromagnetic interference (EMI) in industrial sites; the operating temperature ranges from -25℃ to +60℃, supporting 5%~95% relative humidity without condensation. It also integrates overvoltage protection (≤30V DC), with a mean time between failures (MTBF) of over 100,000 hours, enabling stable operation in complex industrial environments with dust and vibration.

4.Flexible Signal Adaptability

Supporting 24V DC standard industrial voltage input, it is compatible with both NPN and PNP sensor signal types, and can be directly connected to common digital devices such as photoelectric sensors and proximity switches without additional hardware configuration. At the same time, the filtering time (0.1ms~100ms) of each input signal can be customized via TwinCAT software to adapt to on-site devices with different response speeds, avoiding false triggers caused by signal jitter.

5.Convenient Diagnosis & Maintenance

Each input channel is equipped with an independent LED status indicator (green light on indicates normal signal, off indicates no signal), allowing intuitive judgment of the channel's working status. It also supports real-time monitoring of channel faults (such as wiring short circuits and abnormal signals) via TwinCAT software and generates diagnostic logs. Engineers can quickly locate problems without disassembling the module, shortening maintenance time.

Precision Machine Tool Auxiliary Signal Acquisition

In precision machine tools such as CNC milling machines, lathes, and grinders, the EL1252 module is mainly responsible for collecting digital signals from auxiliary components. Examples include signals from limit switches that prevent the worktable from exceeding its travel range, signals from emergency stop buttons used in emergency situations, and signals from coolant level sensors.

Each channel of this module has an isolation voltage of 250V AC, which can effectively withstand the electromagnetic interference generated by machine tool spindles and drive systems, preventing signal mis-triggering caused by electrical noise. Moreover, its signal filtering time can be flexibly set between 0.1 milliseconds and 100 milliseconds, enabling it to adapt to the response characteristics of different sensors. This ensures that safety-related signals are transmitted stably and accurately to the machine tool control system, protecting the normal operation of the equipment and safeguarding the safety of operators.
