Two-channel relay SLA-24VDC-SL-C, 250V/30A on DIN rail

Professional two-channel relay module with SLA-24VDC-SL-C relay type and galvanic isolation using optocouplers. The module is designed for switching devices with voltage up to 250 V AC or 30 V DC and current up to 30 A. Thanks to the support of high and low trigger logic (High/Low Trigger), it is suitable for a wide range of applications in automation, smart home or industrial PLC systems. The robust design with the possibility of mounting on a DIN rail guarantees easy installation and reliable operation.
