【英文介绍】
The Allen-Bradley 1786-RPFRL module is a ControlNet fiber optic ring repeater module. It supports fiber media redundancy by using a ring topology for long transmission distances, electromagnetic interference protection, and ground isolation between nodes. The distance between fiber optic Repeaters depends on many factors, including fiber quality, number of connectors, and number of connectors. For the 1786-RPFRL module, the loss on the fiber link must be less than 15 dB. According to the ControlNet standard, the total length of the fiber ring is limited to 20 km or less. Modules should use plastic or ceramic ST fiber optic connectors. Metal connectors are not supported.
The 1786-RPFRL module provides 2 Fibre channels, active status indicators on each Fibre channel, and relay contact connectors for system status and communication updates. The power input requirement for this module is 570 MA (5 volts DC). The backplane has a power requirement of 2.8 watts (maximum 3.02 watts). The supported communication rate is 5 Mbps. The module can be installed in any direction. The maximum voltage of the relay contactor is 30 volts DC. The minimum and maximum current of the relay contactor are 1 MA and 900 mA respectively. The isolation voltage is rated at 50 volts continuous. The recommended wire size for the 1786-RPFRL module is 22 to 14 AWG solid or stranded copper wire with a temperature rating of 75 degrees Celsius or higher. The 1786-RPFRL module is an open module that complies with the T5 North American temperature specification. The air temperature around the 1786-RPFRL module should not exceed 60 degrees Celsius.
