1747-DCM 直接通信模块 适配器

The Allen-Bradley 1747-DCM is a direct communication module. The module is part of the Allen-Bradley Remote I/O (RIO) series adapter in the SLC 500 series. The application of this module is similar to PLC-5. It distributes the SLC-500 processors across the Allen-Bradley RIO communication link and allows them to transfer data between each other. Each SLC 500 controller can be connected to the Allen-Bradley programmable controller via RIO Link, providing a distributed processing system. The DCM occupies one slot in any 500slc chassis. The Allen-Bradley 1747-DCM is a RIO adapter for integrating the PLC processor of the RIO scanner on the RIO communication link. It is also an adapter for the RIO scanner.

To configure DCM for your application, you need to set the dip switch. This switch allows DCM to correctly interpret the RIO system address. DCM has two dip switch groups installed on its circuit board. Each switch contains eight switches. The 1747-DCM uses the Belden 9463 cable. The Allen-Bradley 1747-DCM has an operating temperature range of 32-140 A °F, while the storage temperature is -40-185 A °F and the relative humidity is 5-95% non-condensing. The 1747-DCM complies with NEMA standard ICS 2-230, EN50081-2 Class A, IEC1000-4-2 and IEC1000-4-3 certifications, and is csa certified.

Allen-Bradley 1747-DCM is a direct communication module that is compatible with SLC 500 fixed style and modular style programmable logic controllers (PLCS). This module allows any SLC 500 controller to establish a connection to a remote I/O (RIO) industrial network.

The 1747-DCM is a single-slot module with a backplane current consumption of 360 MA @ 5 V DC. As a component, it comes with status LED indicators such as FAULT LED and COMM LED. It has a detachable door cover with pre-installed door tags. The front panel of the module has front labels, cable tie slots, and RIO link connectors. On one side of the module, you can access the module information and DIP switch.

The 1747-DCM supports multiple communication speeds and can operate at standard and extended node capabilities. With extended functionality, the module can be configured to 57.6K baud @ 10,000 feet at 57.6K baud; 115.2K baud @ 5000 ft at 115.2K baud and 20.3k Baud @ 2500 ft at 20.3k baud at 82 ohm, 1/2 watt terminal resistors are installed at the start and final nodes. It has standard node capability and supports transfer rates of 57.6K baud @ 3048 m (10,000 ft) and 115.2K baud @ 1524 m (5,000 ft) with terminal resistance of 150 ohms, ½ W. Also supports 20.3 k baud @ 762 m (2500 ft)82 ohm, 1/2 watt terminal resistance.

The 1747-DCM has an operating temperature of 0°C to 60°C(32°F to 140°F), a non-operating temperature of -40°C to +85°C(-40°F to +185°F), and a humidity rating of 5-95% without condensation.
