Product Description:
The EL2258 is a digital output terminal from Beckhoff’s EL EtherCAT Terminals series that provides deterministic signal switching on an EtherCAT I/O strand. Within an automation cell, it acts as a time-stamped interface that allows a controller to trigger actuators at precise instants referenced to the network clock. Its individually addressable channels support applications that require compact and synchronized output blocks alongside other slice-style terminals. The module mounts on a DIN rail, allowing it to be integrated into a distributed control system without occupying excessive panel space.
The terminal operates from a field supply of 24 V DC and provides eight push-pull output channels. Each channel supports a continuous load of 0.5 A per channel, allowing the terminal to control compatible industrial loads directly. An internal FIFO has a capacity of 32 events per channel, enabling the controller to queue multiple switching actions. Each event is executed with a time granularity of 1 ns relative to the EtherCAT Distributed Clocks system. The circuitry accommodates resistive, inductive, and lamp loads without additional signal conditioning, and each port can switch up to ten times during one PLC cycle. Reverse-polarity tolerance protects the electronics from an incorrectly connected field supply. The housing has an IP20 protection rating, which guards against accidental contact with internal electrical components while permitting installation in a suitable control enclosure.
Connections use a 2-wire topology with pluggable spring terminals, keeping field wiring straightforward in densely populated panels. The terminal is only 12 mm wide, allowing multiple modules to fit within limited DIN-rail space. A 32-bit latch captures outgoing timestamps at the network boundary. The controller receives each captured value as a 32-bit word, providing data that can be used to verify execution timing and evaluate jitter. Distributed-clock synchronization coordinates scheduled switching actions across multiple terminals on the same EtherCAT network. The source-and-sink capability of the output stage supports bidirectional current control as required by compatible connected devices.
