140NOC78000 Schneider Relay Module
140NOC78000 is a Modicon Quantum series Ethernet DIO interface
module launched by Schneider Electric, which supports dual Profibus
DP bus and redundant fiber optic ring network topology. It is
equipped with 155M dual optical interface and 1-2 Profibus DP
electrical interfaces, which can achieve fiber optic distance
transmission of more than 20km and 155Mb/s high-speed data
exchange. It is equipped with 6 dual color LED status indicators
for monitoring fiber optic links and power status. It has an IP30
protection level and a corrugated aluminum reinforced casing. It
adopts a 35mm DIN rail installation method, supports DC (9-36) V
wide power input and dual power redundancy, integrates industrial
grade design features such as relay alarm output, lightning
protection, overcurrent, surge protection, etc., and is equipped
with EMC Testing and certification can be applied to various
network topologies such as point-to-point, chain type, star type,
redundant dual network, and fiber ring network. It is suitable for
scenarios in the industrial automation field that require high
communication stability, anti-interference ability, and
environmental adaptability.
