IP20 EtherCAT Terminal 2ms Filter

Beckhoff EL1904 | EtherCAT Terminal 4× DI 24V DC, 2ms Filter, 1-Wire, IP20 — Safety-Related Option Available
Beckhoff EL1904 EtherCAT digital input terminal — 4 × 24 V DC inputs (IEC 61131-2 Type 1/3), 2 ms filter, 500 V isolation, 12 mm width. For use with BK/EK series couplers. EL1904 = std. DI; EL1904 with -xxxx safety option = safe DI per EN ISO 13849-1.

Product Overview

The Beckhoff EL1904 (Art. No. EL1904 | often quoted as EL1904-0000 meaning no special option / standard version)​ is an EtherCAT digital input terminal​ providing four electrically isolated 24 V DC inputs (sink/source — Type 1 / Type 3 per IEC 61131-2)​ for connection to the Beckhoff EtherCAT I/O system (EK1100 coupler or CX series embedded PCs with E-bus). Each input has a 2 ms (typical) debounce filter​ and the terminal draws its logic power from the E-bus (no external 24 V auxiliary needed for electronics). Signals are scanned at EtherCAT cycle time and transmitted in the process image. The EL1904 occupies 4 bits (1 byte)​ in the input process image. Width is 12 mm (standard EtherCAT terminal format). Also available as EL1904 with safety option (e.g. EL1904-0000 with -SIL or as EL1904 in TwinSAFE SC context)​ — base hardware is identical; TwinSAFE functionality is enabled via configuration and FSoE (Fail Safe over EtherCAT) when used with EL6910 or other TwinSAFE Logic Terminals.

Technical Specifications (Electrical & I/O)

Parameter
Specification
Article / Order Code
EL1904-0000​ (EL1904 standard digital input terminal, no option — "0000" = default)

Technical Specifications (Mechanical & System)

Parameter
Specification
Terminal Width
12 mm​ (standard EtherCAT EL terminal)
Connection Method
Spring-cage (Push-in) — 2 × 4-pin removable terminal block (top row = inputs + 24V sense; bottom = 0V common)
Conductor Size
Solid: 0.08–2.5 mm² / Stranded with ferrule: 0.08–1.5 mm²
Power Supply for Electronics
From E-bus (≤ 90 mW typ.) — no external 24 V aux for terminal logic
Sensor Supply (Optional Use)
User typically wires 24 V DC from external PS to terminal's sensor supply terminals (not consumed by EL1904 — pass-through)
Process Image Size
4 bits (1 byte) input​ — mapped in TwinCAT automatically
Distributed Clocks
Supported — input timestamping possible when configured
Mounting
35 mm DIN Rail (EN 60715 / TS 35) — snap-on with locking lever
Operating Temp.
0 … +55 °C​ (storage -25 … +85 °C)
Degree of Protection
IP20 (installed in cabinet)
Weight (Approx.)
55 g
Certifications
CE, UL 508, cULus, EAC, KC, RoHS / REACH
TwinSAFE Capable
Base EL1904 can be used as FSoE Safe Input​ when paired with TwinSAFE Logic Terminal (EL6910 / EL6900) — requires FSoE license & configuration; hardware itself is not a safety controller

Key Features

  • Compact 4 DI in 12 mm:​ High-density EtherCAT I/O — minimizes cabinet width per point vs. older KL series (24 mm).
  • E-bus Powered Electronics:​ No auxiliary 24 V wiring to the terminal itself — only field 24 V DC for sensors.
  • 2 ms Debounce Filter:​ Rejects contact bounce and electrical noise from relays/prox switches — configurable in software for longer filter times.
  • PNP/NPN Universal:​ Accepts both sourcing and sinking sensor wiring — one part covers most panel standards.
  • TwinSAFE FSoE Ready (with Logic Terminal):​ Same hardware can serve as safe input (up to SIL 3 / PL e) when used in a TwinSAFE FSoE network — no separate safety DI terminal needed for small systems.

Typical Applications

  • Machine Control I/O Rack:​ Read limit switches, E-STOP (via safety relay / TwinSAFE), pushbuttons, and prox sensor states into Beckhoff CX or EK1100+E-bus coupler.
  • Packaging / Converting Lines:​ High-speed DI acquisition synchronized via EtherCAT Distributed Clocks — suitable for registration marks or encoder Z-pulse (when using EL1262 high-speed DI; EL1904 covers general-purpose DI).
  • Process Skid Distributed I/O:​ Compact EtherCAT node near field devices — less wiring vs. central parallel cabling.
  • TwinSAFE Pilot Projects:​ Start with EL1904 as standard DI; later activate FSoE inputs with TwinSAFE Logic Terminal — no hardware change needed.
