196 UI Card - Direct Replacement for 16 Universal Input Card

196 UI card – Direct replacement for 16 universal input card

The 16-channel input card is meticulously crafted to seamlessly integrate into existing Satchwell BAS 2000, 2800, and Sigma rack-type control enclosures (UNC 696 and UNC 796 controllers), facilitating the interfacing of current analogue and digital inputs with a modern, web-based master controller via a Modbus two-wire RS485 network. This versatile card boasts 16 inputs, each configurable via jumpers to accommodate voltage measurements spanning 0 – 10V, current readings within the 0 – 20mA range, or resistance measurements, catering to PTC and NTC thermistors, with precision maintained across two distinct ranges for utmost accuracy. Digital signal readings are facilitated by customizable thresholds, adjustable over the Modbus network. Furthermore, the inputs offer precise pulse-counting capabilities and frequency calculation of variable signals, with dedicated LEDs for each input providing real-time status updates, controllable via the Modbus network. Communication with the card occurs seamlessly through Modbus over a two-wire RS-485 network, utilizing an 8-bit RTU data format. Configuration parameters such as address, baud rates, and message formats are effortlessly adjusted via dip switches, ensuring flexibility and ease of integration (refer to Section 1.3 for detailed instructions). For commissioning convenience, a software set-up tool is at hand, enabling hassle-free configuration via a supervisor port, even in the absence of the master controller and Modbus network. Accessing input values is simplified by selecting from a wide array of 34 pre-installed profiles via the Modbus register. These profiles encompass all common current, voltage, and thermistor types, ensuring compatibility and streamlining integration (refer to Section 2.3 and Appendices A & C for comprehensive details). The card requires a 24VDC power supply for operation, ensuring consistent and reliable performance. Furthermore, inputs are safeguarded against static discharge, providing enhanced durability and protection against environmental factors, ensuring uninterrupted operation in various conditions.
