Interface and Communication Board for Isocenter Verification System

Product Specifications

Technical details and manufacturing context for Interface and Communication Board

Definition

The Interface and Communication Board is a specialized printed circuit board (PCB) designed for use within the Isocenter Verification System. Its primary function is to manage all input/output (I/O) operations, protocol conversion, and data communication between the verification system and external devices or networks. Acting as the central hub, it interfaces with user control panels, medical imaging systems, network connections, and peripheral sensors, ensuring accurate and reliable transmission of verification data and system commands.

The board is built on an FR-4 PCB substrate with copper traces and surface-mount electronic components, including integrated circuits, resistors, capacitors, and connector headers. It operates with a supply voltage of 24 V DC (±10%) and is reverse polarity protected, conforming to IEC 61131-2. Power consumption ranges from 5 to 15 W, depending on connected peripherals. The board is designed for industrial environments, with an operating temperature range of -40 to 85 °C and a storage temperature range of -55 to 125 °C, tested according to IEC 60068-2-1/2. It withstands non-condensing humidity from 5% to 95% RH (IEC 60068-2-78) and offers ingress protection ratings from IP54 to IP65 with a mating connector (IEC 60529).

Communication interfaces include two opto-isolated CAN buses and one RS-485 port, compliant with ISO 11898 and TIA/EIA-485, respectively. An Ethernet port supports data rates from 10 to 1000 Mbps (IEEE 802.3). The board provides 8 to 16 configurable digital I/O channels and analog input resolution of 12 to 16 bits, both per IEC 61131-2. Isolation voltage between field and logic is 1500 V DC (IEC 61010-1). The mean time between failures (MTBF) is 100,000 hours at 40 °C ambient, per IEC 61709. Dimensions are 160 × 100 × 40 mm for DIN rail mounting, and weight without connectors is 200 to 300 g.

All specifications are reference values and must be verified with the legal manufacturer or supplier for the specific model and application.

Working Principle

The board receives analog or digital signals from sensors and user interfaces. These signals are processed by embedded microcontrollers or FPGAs, which convert the data into appropriate communication protocols such as Ethernet, RS-232, USB, or CAN bus. The processed data is then transmitted to connected systems. Conversely, the board receives commands and data from external sources, processes them, and relays instructions to other system components to execute verification routines. This bidirectional communication ensures seamless integration and control within the Isocenter Verification System.
