Internal Product Review
The IE2403 is a Beckhoff IE extension box unit with 8 digital inputs and 8 digital outputs. Control-fieldbus isolation via IP-Link supports clean signal handling, and the IP20 protection class suits enclosed control cabinets well. A 24 VDC rated load voltage and 0.5 A per channel output capability make the IE2403 a strong choice for dependable distributed I/O integration.

Product Description:
The IE2403 is an extension box unit manufactured by Beckhoff for the IE Extension Box Units series. This compact module serves as a field-mountable block that brings remote I/O connections to production equipment, reducing the need for extra cabinet wiring. It exchanges data with the higher-level bus through IP-Link, allowing controllers to read signals from sensors and operate actuators positioned on the machine. The device expands digital capacity close to the process and supports installations where space and response time are important. Its compact format also allows the I/O connections to be distributed near the equipment they control rather than concentrated in a central enclosure.
The unit provides 8 digital inputs and 8 digital outputs, which are mapped to the controller through the process image. All channels operate from a 24 VDC supply commonly used in industrial control systems. Each output can source up to 0.5 A per channel, allowing direct operation of relays, solenoids, or indicator lamps without external amplifiers. The IP20 housing protects against accidental contact with hazardous internal parts and the entry of solid objects larger than the permitted limit. Because this protection level does not provide water resistance, the unit should be installed in a suitable enclosure when exposure to moisture is possible.
Communication integrity is supported by IP-Link isolation, which helps prevent ground loops between the control fieldbus and the local I/O reference. Input debouncing is handled by a 3.0 ms input filter, preventing brief electrical noise from appearing in the controller image as a valid signal. Each input draws a sensor load of 20 mA per channel, while the output circuitry can tolerate a fault current of up to 1.5 A before short-circuit protection responds. A four-pin M8 socket provides the downstream connection, and a matching four-pin M8 connector supplies power. Signal lines terminate at the KM Connector ZS2001, providing pluggable connections for the field wiring. The available sensor supply delivers 0.5 A for connected input devices.
