Product Description

​The Phoenix Contact IBS RL 24 DIO 8/8/8-LK-2MBD is a distributed digital I/O device designed for seamless integration into the INTERBUS system. It offers eight 24 V DC digital inputs and eight 24 V DC digital outputs, each capable of handling up to 0.5 A, facilitating efficient sensor and actuator connectivity. Utilizing fiber optic technology with a transmission speed of 2 Mbaud, the device ensures reliable and high-speed data communication. Sensor and actuator connections are established via 5-position M12 female connectors, simplifying the setup process. Housed in a rugged metal enclosure with IP67 protection, it is well-suited for demanding industrial environments requiring durability and resistance to harsh conditions. ​
