Product Description

Description

The Beckhoff EL3102 is a 2-channel analog input terminal designed to process differential voltage signals in the range of -10 V to +10 V with a 16-bit resolution. Operating on the EtherCAT system protocol, this device digitizes analog measurement signals and transmits them electrically isolated to the higher-level automation system via the E-bus. It features integrated Distributed Clocks to enable precise, synchronous signal acquisition with high time accuracy across the network. Built-in processing options include standard and compact process images, switchable measuring data representation, activatable FIR/IIR digital filters, and limit value monitoring.

Features

Two differential analog voltage input channels (-10 V to +10 V)
16-bit resolution including sign for high-precision measurement
Distributed Clocks support with precision significantly under 1 us
Switchable measuring data representation and activatable FIR/IIR digital filters
Hardware-level limit value monitoring and standard/compact process image options
Galvanic isolation of 500 V between the E-bus and signal voltage

Applications

Multi-axis motion control requiring precise synchronous voltage feedback
High-accuracy sensor signal acquisition in industrial automation
High-speed test benches and signal monitoring systems
Process control systems using standardized -10 V to +10 V interfaces

Installation Guidelines

DIN Rail Mounting: Install on a 35 mm DIN rail according to EN 60715. Engage the locking mechanism securely.
Side-by-Side Mounting: Join adjacent terminals using the integrated double slot and key connection system.
Wiring: Insert solid, stranded, or ferruled conductors into the spring-clamp terminals by actuating the mechanism with a screwdriver. Maintain a stripping length of 8 mm to 9 mm.
Environmental Considerations: Ensure the installation environment maintains protection class IP 20 standards and remains within operating limits (-25 degC to +60 degC, non-condensing).
