Product Description

Beckhoff, a pioneer in industrial automation technology, produces the EL1502 EtherCAT Terminal counter module. Applications requiring accurate and quick counting operations are the target market for this module. Fundamentally, the EL1502 has one or two counters with a 32-bit depth each, which allows it to do a variety of counting jobs. For most industrial applications, this 32-bit depth translates to a maximum count of 4,294,967,295. With a tolerance of -15%/+20%, the module functions at a nominal voltage of 24 V DC, guaranteeing dependable performance even in the presence of slight voltage variations. Because industrial control systems often employ this voltage level, the EL1502 may be readily incorporated into pre-existing configurations. The remarkable counting frequency of the EL1502, which may reach up to 100 kHz, is one of its important performance indicators. This indicates that the module is appropriate for high-speed applications like tracking encoder signals, detecting quick occurrences, or monitoring manufacturing line outputs since it can precisely record up to 100,000 events per second.

Distributed clocks are also included into the EL1502. In intricate automation systems, this characteristic improves timing precision and synchronization. The system may accomplish accurate coordination, reduce latency, and enhance overall performance by dividing clock signals across many components. The maximum output current of the EL1502 is 0.5 A per channel in terms of electrical properties. A variety of external devices, including solenoids, indication lights, and actuators, may be powered by this output current. The output of the module is short-circuit proof, preventing unintentional short circuits and guaranteeing the life of the gadget. While the E-bus current consumption is normally 130 mA, the EL1502's power contacts consume a current of 14 mA + the load current. When it comes to power supply size and overall system efficiency, these variables are crucial.

The EN 61131-2 specification, a well-known benchmark for programmable logic controllers (PLCs), is followed by the EL1502. This conformance facilitates system integration and encourages standardization in industrial automation by guaranteeing compatibility and interoperability with other systems and devices that adhere to the same standard. Specific voltage levels for logic signals are also defined by the EN 61131-2 standard; "0" denotes less than 5 V DC, and "1" denotes more than 15 V DC. By adhering to specified voltage values, the EL1502 guarantees accurate signal interpretation and control system communication. Wake Industrial provides clients with peace of mind and product quality assurance by offering a one-year warranty on the EL1502.
