1786-RPCD is the ControlNet repeater module for Allen-Bradley. 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 and can be installed with up to four (4) 1786-RPcds and one repeater adapter. The 1786-RPCD comes with two (2) ControlNet ports supporting RG6 coaxial cable. With dual ControlNet ports, this adapter module can be used to extend ControlNet networks in linear, star, and redundant topologies. In addition to the above topology, the 1786-RPCD is also used in the ControlNet network based on hubs to achieve longer ControlNet distance coverage and to achieve isolated ControlNet network segments. Unused port channels must be plugged into a 75 ohm mainline terminating resistor with Allen-Bradley catalog number 1786-XT. 1786-RPCD Receives power from the relay adapter module. It has a backplane current consumption of 400 mA at 5VDC, a maximum power consumption of 2 watts and a maximum power consumption of 2 watts. It has an open housing, so the module should be installed inside the housing to provide adequate protection from industrial elements. The module operates at a temperature of 0-60 degrees Celsius. The 1786-RPCD has two (2) LED status indicators, such as channel 1 and Channel 2 indicators. When the module is running, the LED lights up 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 35 mm 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 the RPA/B repeater adapter that supplies it with 5 volts of DC, and the backplane current consumption is 400mA at a maximum of 5 volts of DC. The 1786-RPCD is designed to extend network length, provide point-to-point topology, or perform network media conversion 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 of 5g at 10 to 500 Hz and a relative humidity range of 5% to 95% for non-condensing humidity. The 1786-RPCD is powered by a repeater adapter. The 1786-RPCD can easily connect multiple 1000m copper segments to a single repeater adapter (1786-RPA). It provides two copper channels and activity status indicators for each channel. The 1786-RPCD consists of two status indicators, which are interpreted by the operator to communicate failure conditions and whether power is on, including whether there is a fault in the data acquired by the module. Its delay value is 100ns. When installing the 1786-RPCD, place the 1786-RPCD module at a 30 degree Angle. Hook the lip on the back of the module to the top of the DIN rail, then rotate it onto the track. Then press the module onto the DIN rail until it appears flush. At the same time, the locking disc should snap into the correct position and lock the module to the DIN rail. If necessary, slide the module to the left to connect to the repeater adapter or other repeater modules. Observe when inserting or removing modules. It is not recommended to remove or add the 1786-RPCD module with power on. The power supply 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 concentrator-based topologies and where network segments require longer copper wire distances; The network design requires a separate section, and the number of nodes also requires Repeaters.
