490NRP25400 Schneider Relay Module
490NRP25400 is a Modbus Plus bus fiber optic repeater launched by Schneider Electric. As an industrial grade fieldbus device, it adopts a redundant dual bus structure design, equipped with two independent Modbus Plus electrical interfaces and two 155M fiber optic interfaces. It supports various topology structures such as point-to-point, chain type, star type, redundant dual network, and fiber ring network self-healing protection. Through the dual optical ports, it can achieve long-distance transmission of more than 20km and complete link reconstruction within 10ms in case of fiber optic failure, ensuring the continuity of system communication; The equipment adopts a wave patterned aluminum reinforced casing with IP30 protection level, supports 35mm rail installation, and has a working voltage range of DC9-36V. It has dual power redundant input, DC1500V power isolation and reverse protection functions, and integrates relay alarm output function, which can monitor the fiber optic link and power status in real time; This product is compatible with Modbus Plus fieldbus SER1 and SER2 industrial terminal wiring, with a communication speed of up to 1M. It supports multi-mode (850nm/1310nm) and single-mode (1310nm/1550nm) fiber optic transmission, suitable for multi-mode 2Km and single-mode 20Km distance scenarios. It comes standard with ST optical interface (optional SC, FC) and can flexibly combine 1-2 electrical and optical ports to meet different project requirements; Its logically independent dual bus electrical interface design supports single device access to dual redundant bus systems, or connects two Modbus Plus bus segments through a point-to-point network. Combined with a dual optical port chain network, it can achieve up to 200 Modbus Plus bus connections, suitable for industrial scenarios such as mechanical manufacturing, power plants, and petrochemicals that require strict network reliability.
