power relay for versatile control: supports up to DC 30V 30A or AC 250V 30A, enabling direct switching of motors, heaters, lights, and other loads within these limits. Strong noise and interference resistance: each channel uses optocoupler isolation to reduce electrical noise and protect the control signal from disturbances. Safe separation between control and load: designed with a clear isolation slot between the control area and the load area in accordance with international safety standards, helping to keep control circuitry safe from power transients. Clear status indication: every channel includes an LED indicator for immediate visibility of relay status, simplifying monitoring and troubleshooting. Multichannel reliability: independent channel design provides reliable operation across multiple loads with individual status feedback. Specifications at a glance Maximum control load: DC 30V 30A / AC 250V 30A Isolation: optocoupler isolation per channel Safety: control area and load area separated by isolation slot, in line with international standards Indication: each channel has a relay on LED indication Use scenarios Microcontroller driven automation: connect a microcontroller, Arduino, or similar controller to switch DC motors or AC devices up to the listed limits with isolation and clear LED status per channel. Industrial panel integration: use in control cabinets to drive pumps, heaters, or solenoids while maintaining isolation between the control electronics and power loads. Home and building automation: manage lighting, HVAC actuators, or other electrical loads in a safe, isolated manner, with straightforward status monitoring for maintenance. Why choose this product Directly capable of handling common DC and AC loads within its rated voltages and currents, reducing the need for additional relays. Independent channel isolation enhances signal integrity and protects control electronics in noisy environments. Compliance with safety standards and a clear controlload separation contribute to safer, more reliable operation in both small projects and larger control systems. Perchannel LED indicators simplify setup, testing, and ongoing diagnostics.
