1786-RPCD 一种控制网中继器模块

The 1786-RPCD is an Allen-Bradley control network repeater module. This module is primarily used to extend the existing ControlNet network. This repeater module is used with a repeater adapter with directory number 1786-RPA/B. Up to four (4), 1786-RPCD can be installed with a single repeater adapter. The 1786-RPCD comes with two (2) ControlNet ports supporting RG6 coaxial cable. With dual control network ports, the adapter module can be used to extend control network networks with linear, star and redundant topologies. In addition to the above topologies, the 1786-RPCD is also used in concentrator-based control network networks to achieve longer control network distance coverage and to achieve isolated control network segments. The unused channel of the port must be plugged in with a 75 ohm trunk line terminal resistor, Allen-Bradley catalog number 1786-XT. 1786-RPCD Receives power from the relay adapter module. It has a backplane current of 400ma at 5VDC, a maximum power consumption of 2 watts, and a maximum power consumption of 2 watts. It has an open housing, so this module should be installed inside a housing that provides adequate protection against industrial elements. The module operates at a temperature of 0-60 degrees Celsius. The 1786-RPCD has two LED status indicators, such as channel 1 and Channel 2 indicators. When the module is working, the LED is bright green, and the LED of the active communication channel flashes green. The module measures 4.048 inches or 101.2 mm (height); 4.44 inches or 111 mm (width) and 2.76 inches or 69 mm (depth). It is mounted on a standard 35mm DIN rail.

The 1786-RPCD is a coaxial repeater module control network manufactured by Allen-Bradley. The 1786-RPCD coaxial repeater module is connected to an RPA/B repeater adapter that provides it with 5 volts DC and 400mA backplane current at a maximum of 5 volts DC. The 1786-RPCD is designed to extend network length, provide point-to-point topology, or convert network media from coaxial media to fiber media, and vice versa. The 1786-RPCD has an operating temperature of 32 to 140 degrees Fahrenheit and a non-operating temperature of 60 degrees for RF immunity according to IEC 61000-4-5 standards. It has a vibration frequency of 5g, a frequency of 10 to 500 Hz, and a relative humidity range of 5% to 95%(non-condensing humidity). The 1786-RPCD is powered by a repeater adapter. The 1786-RPCD makes it easy to connect multiple 1000 meter copper segments to a single repeater adapter (1786-RPA). It gives two copper channels and an activity status indicator for each channel. The 1786-RPCD consists of two status indicators, which the operator interprets as a communication failure condition and whether it is being powered on, including whether there is a failure in the data acquired by the module. Its delay value is 100ns. When installing the 1786-RPCD, tilt the 1786-RPCD module 30 degrees. Hook the lip on the back of the module to the top of the DIN rail and rotate it onto the track. The module is then pressed against the DIN rail until it appears flush. At the same time, the locking tag should snap into the correct position and lock the module onto the DIN rail. If necessary, slide the module to the left to connect to the repeater adapter or another repeater module. Observe carefully when inserting or removing a module. It is not recommended to remove or add the 1786-RPCD module while live. Power should be turned off when entering and disconnecting, and the area should be determined as a no-danger area. The 1786-RPCD is suitable for networks that require a hub based topology and where the network segment requires a long copper wire distance; The design of the network requires segmentation, and the number of nodes also requires Repeaters.
