Controller Installation

24VDC Power Cabling

In order to maintain compliance with EN standards, DC power must be delivered over a shielded cable, with the shield connected to the return conductors at both ends of the cable as shown in Figure 2-6. Conductors should be 1.5 mm2- 1.85 mm2 (16 to 14 AWG) in size. The maximum length for the 24VDC cable is 10 meters.

Daisy-Chaining Power

The SmartController is equipped with two DC power connectors. These connectors allow the daisy-chaining of power from one controller to another or to a sDIO module. When daisy-chaining power, the power supply circuit must be limited to the lesser of 8 Amps or the ampacity of the cabling. This can be done with a circuit breaker or a fuse. The DC power can be applied to either the XDC1 or XDC2 connector.

CAUTION: Use only one 24VDC power supply per circuit.

Failure to do this could result in damage to the equipment.

Grounding

The SmartController is equipped with a grounding point. See Figure 2-7. Adept recommends connecting a ground wire from the ground point on the controller to earth ground and that all other interconnected Adept components share the same electrical ground potential. The ground wire must meet all local regulations. Additional grounding information for other Adept products are provided in the documentation for those products.

NOTE: The maximum length for the ground wire for the SmartController is 3 meters.

RS-422/485, XSYS, XUSR, RS-232/TERM specifications

Nortech Systems offers a comprehensive suite of serial communication solutions, including RS-232/TERM, XUSR, XSYS, and RS-422/485 interfaces. These products are designed to facilitate reliable and high-speed data transmission in various industrial applications, making them essential for connecting devices in automation, telecommunications, and data acquisition systems.

The RS-232/TERM interface is a widely adopted standard for serial communication, known for its simplicity and robustness. It supports point-to-point communication over relatively short distances, typically up to 50 feet. Key features include a maximum baud rate of up to 115.2 kbps, error-checking capabilities, and a straightforward connection process, making it ideal for connecting peripheral devices like printers, modems, and barcode scanners.

Building on the RS-232 standard, the XUSR and XSYS devices offer enhanced functionalities and flexibility. XUSR, for instance, supports not just traditional RS-232 connections, but also protocol conversion for various serial interfaces, facilitating seamless integration of legacy systems with modern networking technologies. It is particularly useful in environments where multiple protocols need to be managed simultaneously.

XSYS is designed for more complex applications and supports advanced communication features such as multi-drop configurations, enabling it to connect multiple devices on a single bus. This makes it suitable for extensive industrial networks where space and wiring complexity need to be minimized. Synchronous and asynchronous data transfer modes ensure that the XSYS is adaptable for both real-time data collection and standard command-response applications.

On the other hand, RS-422/485 interfaces excel in long-distance communication, allowing for data transmission over distances up to 4,000 feet. They are designed for multi-point connections, supporting up to 32 devices on a single bus through differential signaling, which enhances noise immunity. These characteristics make RS-422/485 particularly well-suited for environments with electromagnetic interference, such as factories or subways.

Nortech Systems’ serial communication solutions emphasize reliability, ease of use, and versatility. With their commitment to high performance and user satisfaction, these interfaces provide critical connectivity in today’s increasingly automated and interconnected world. Whether in data centers, manufacturing setups, or remote sensor networks, Nortech's offerings stand out for their reliability, efficiency, and adaptability, ensuring effective data communication across diverse applications.
