Aalborg Instruments Smart Digital Command Module SDPROC4C2UKL

The Smart Digital Command Module (part number SDPROC4C2UKL) 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 supports configurations of one to four channels and includes a 24x2 alpha-numeric dot matrix display along with four panel buttons for user control. This module features an easy-to-navigate programming interface with a modular menu structure, allowing quick access to various functions. 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 supports programmable batch flow control with up to sixteen steps, as well as programmable timer flow control with up to 96 steps. The module can preprogram high and low flow alarm limits for each channel, with customizable actions such as contact closures or audible signals. It also provides totalizer functionality to calculate the total volume of gas flow over time, with options to set, start, stop, and read totalizer values. The device operates on a wide power supply range of 85 to 240 VAC and includes various engineering units for flow measurements. Its compact dimensions and lightweight design make it suitable for various applications in flow measurement and control.
