Description

The EL1862 digital input terminal reads 24 V DC signals from sensors or switches.
It offers 16 channels in a very small footprint.
A 20-pin IDC connector simplifies wiring of many channels.
The 3 ms input filter rejects mechanical switch bounce.
LEDs show the signal state per channel.
This terminal is ideal for high-density I/O applications.

Expert Review

“The EL1862 is a workhorse for high-channel-count digital inputs.
The 3 ms filter is ideal for noisy industrial environments.
IDC connection saves panel space and wiring time.
Reliable, robust, and cost-effective.”

Manager’s Insight

“For machine builders, this terminal reduces assembly errors.
Ribbon cable wiring is faster than individual wires.
The UL and ATEX approvals make it suitable for global projects.
Stock availability ensures short lead times.”

Applications & Suitable Devices

• PLC I/O expansion – connect sensors, switches, pushbuttons.
• Factory automation – conveyor systems, packaging machines.
• Process control – valve feedback, level switches.
• Robotics – end-effector signals, safety interlocks.
• Works with Beckhoff CX, CP, and EP series controllers.

FAQ

• What cable type is required?
  Use flat-ribbon cable with AWG 28 and 1.27 mm pitch.
• Can I connect mechanical switches?
  Yes. The 3 ms filter eliminates contact bounce.
• Do I need to set addresses?
  No. The EL1862 auto-detects in the EtherCAT network.
• Is it ATEX certified?
  Yes, Ex nA IIC T4 Gc for Zone 2 hazardous areas.
• What is the power consumption?
  E-bus: typ. 100 mA; power contacts: 4 mA from 24 V.
• Can I ground the inputs?
  Yes. The terminal supports ground-switching variant.

Selection Guide

• For 16 channels in small space → EL1862 is the best choice.
• If you need faster filter, consider EL1860 (no filter).
• For fewer channels, choose EL1809 (8-channel) or EL1819 (16-channel with different connection).
• Use EL1862 with ribbon cable for high-density cabinets.
