The EL2502 is a 2-channel Pulse Width Modulation (PWM) output terminal from Beckhoff Automation, designed for precise control and synchronization of binary signals. Here's a detailed description:

• Nominal Voltage: Operates at 24 V DC (-15%/+20%).

• Number of Outputs: Two channels, each capable of PWM output.

• Output Current: Maximum 0.5 A per channel, short-circuit proof.

• Base Frequency: Adjustable from 1 Hz to 125 kHz, with a default of 250 Hz.

• Duty Cycle: Configurable from 0% to 100%, with pulse durations greater than 750 ns and pause durations over 500 ns.

• Resolution: Varies from 9 to 15 bits depending on the frequency.

• Electrical Isolation: 500 V between the E-bus and field potential.

• Special Features: Separate frequency settings for each channel, reverse voltage protection, and overload protection.

• Physical Dimensions: Approximately 15 mm x 100 mm x 70 mm.

• Operating Temperature: 0°C to +55°C.

• Storage Temperature: -25°C to +85°C.

• Protection Class: IP20.

• Approvals: CE, UKCA, EAC, cULus, ATEX, IECEx.
