Detailed Product Description
|
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. Technical specifcations for 490NRP25400 Brand and model: Schneider, model 490NRP25400. Interface configuration: Electrical interface: 1-2 Modbus Plus electrical ports, compatible with Modbus Plus fieldbus SER1 and SER2 industrial terminal wiring, with a communication rate of 1M. Fiber optic interface: 2 155M fiber optic interfaces, supporting multimode (850nm, 1310nm) and single-mode (1310nm, 1550nm) fiber optic transmission. Network topology and transmission performance: Supports various topology structures such as point-to-point, chain type, star type, redundant dual network, and fiber ring network self-healing protection. Fiber optic transmission distance: 2Km for multimode and 20km for single-mode. Signal delay (optical port): 2.3us. Power supply and protection: Power input: Dual power redundant input, DC(9~36)V, Typical DC24V, power consumption less than 4W. Equipped with DC1500V voltage isolation and reverse protection function. Relay alarm output: fiber optic link fault and power supply fault alarm output, contact capacity: DC48V/1A. Electrical and mechanical characteristics: Isolation voltage: Instantaneous isolation voltage of 5000V, continuous isolation voltage of 1000V. Lightning protection, overcurrent, and surge protection: The electrical interface has 4000V lightning protection, 1.5A overcurrent, and 600W surge protection. Dimensions: (147x118x54) mm. Protection level: IP30, reinforced with wavy aluminum casing. Installation method: 35mm rail installation. Net weight: 800g. Environmental adaptability: Working temperature: (-10~+70) ℃, optional wide temperature range (-40~+85) ℃. Relative humidity: ≤ 90% (no condensation). Storage temperature: (-40~+85) ℃. Functional features: Supports logic independent dual Modbus Plus bus and the predetermined communication rate specified in the standard specifications. The dual port chain network can achieve Modbus Plus bus connections for multiple network segments (up to 200). Adopting the proprietary ring network protocol Ci ring, it achieves fast ring formation and ring removal, plug and play, and does not require configuration. When a fiber optic failure occurs, the system will rebuild the network link within 10ms to ensure normal communication of the system. More Products In Stock:
