Designed to deliver highly precise current-controlled modulation within distributed control networks, the Beckhoff EL2535-0050 functions as a dual-channel pulse-width modulation (PWM) output terminal for 24 V DC applications. This compact 12 mm module modulates inductive loads up to 50 mA with a default switching frequency of 30 kHz. Featuring integrated push-pull outputs and two auxiliary 24 V DC digital inputs, it enables responsive closed-loop control of thermoelectric coolers, miniature DC motors, and proportional valves directly on the EtherCAT segment.

Unlike the standard voltage-controlled PWM terminal counterparts, the specialty current-controlled EL2535-0050 regulates output current directly to compensate for temperature-dependent coil resistance variations. Ensure TwinCAT 2.11 (or higher) is configured with the correct XML device description (ESI) file to avoid driver mismatch faults during hardware scanning.
This terminal requires a minimum inductive load of 1 mH. Connecting highly capacitive or purely resistive loads with low inductance values can cause high-frequency oscillations, trigger internal short-circuit limits (under 500 mA), and prevent steady current regulation. In high-density mounting arrays, ensure vertical installation alignment to allow adequate passive thermal dissipation across the polycarbonate terminal housing.
Due to the 30 kHz carrier frequency, we advise utilizing shielded twisted-pair (STP) cabling for connection to the actuator coils. Run the shield to an external grounding clamp (such as the Beckhoff KL9080 shield terminal) as close to the entry point of the electrical cabinet as possible to prevent electromagnetic interference from bleeding into parallel low-voltage analog signals.
CRITICAL WARNING
Isolate all 24 V DC field-side power contacts and standard E-bus power supplies before installing, removing, or wiring any EtherCAT terminals. Electrostatic discharge and hot-swapping can damage sensitive internal bus components.
Align the terminal side-by-side using the double slot-and-key system, then slide it firmly onto a standard 35 mm DIN rail (conforming to EN 60715) until the lock clicks.
Strip wire leads to exactly 8 to 9 mm. Use a flathead screwdriver to depress the spring-actuated terminal mechanism, insert the wire, and release to secure. Solid or ferruled conductors can be pushed directly.
Verify connection cross-sections: use AWG 28 to 14 for solid/stranded wires, and AWG 26 to 16 for wires terminated with ferrules.
