The KZ-R16R is a high-performance 16-channel relay module, specially designed for industrial automation control scenarios to achieve precise switching of multi-channel signals and load driving. The module adopts high-reliability electromagnetic relays, with each contact rated for AC 250V/10A or DC 30V/10A, supporting normally open (NO) contact output. It can stably drive industrial loads such as motors, solenoid valves, and indicator lights, avoiding contact wear caused by frequent on-off operations, with a service life of over 100,000 cycles. Equipped with an RS-485 communication interface and supporting the Modbus-RTU protocol, the module enables remote batch control via upper computers (e.g., PLCs, industrial computers) without on-site manual operation, significantly improving control efficiency. It also features overcurrent protection and surge suppression functions to effectively prevent damage to the module from abnormal load currents. With a DIN rail mounting design, the compact body (120mm×80mm×60mm) fits the standardized layout of industrial control cabinets. Its operating temperature range is -20℃ to +60℃, and it tolerates humidity of 30%-90% (no condensation). Widely used in production line equipment linkage, intelligent power distribution systems, warehouse logistics automation, etc., it provides a stable and reliable signal execution solution for industrial control.
