Aalborg Instruments Smart Digital Command Module SDPROC3A1AUV

The Smart Digital Command Module (part number SDPROC3A1AUV) from Aalborg Instruments is a microprocessor-driven device designed for use with analog or digital mass flow controllers that utilize 0-5 Vdc input/output signals. It is available in one to four channel configurations and features a 24x2 alpha-numeric dot matrix display along with four panel buttons for comprehensive control over flow measurement and regulation. This module supports easy programming through a modular menu structure, allowing users to access functions efficiently. It includes standard RS-232 serial communication via a 9-pin ,ÄúD,Äù connector, and an optional built-in Ethernet interface for remote access through a web browser or TELNET console. The device offers programmable batch flow control with up to sixteen steps, as well as timer flow control with up to 96 steps, enabling precise flow management. The module can preprogram high and low flow alarm limits for each channel, with customizable actions such as contact closures or audible signals. It supports various engineering units for flow measurements and allows users to set control signals from internal, external, or program modes. The totalizer function calculates the total volume of gas flow over time and can be controlled via the keypad or digital interface commands. With a power supply range of 85 to 240 VAC and a compact design, the Smart Digital Command Module is suitable for diverse applications requiring accurate flow control and monitoring.
