This module provides a lot of functionality in a small package. With both rough and high vacuum sensors, integrated electronics, and built-in digital display, all that is required for basic operation is that it be provided with DC power of suitable voltage, current capacity, and quality (requirements are in the manual, available on-line; see comments later in this description). Many of the common operations - including ionization gauge on/off and degas, Conductron calibration, and configuration of set points - may be carried out through the local user interface of push buttons and LED display. For partial remote control, some common operations can also be carried out through use of simple electrical inputs; trip point relays and analog output are available for system control and remote reading/logging of the pressure. The RS-485 interface is available for comprehensive operation of the whole package. A data sheet for this module is available in .PDF format from the Brooks Automation web site, on their literature page as "Granville-Phillips Series 356 Micro-Ion Plus Module". The full manual is also available from them in .PDF format, under Support-->Literature Library-->Manuals-->Module Manuals, "356 Micro-Ion Plus Vacuum Gauge Module with Analog RS-485 Interface Installation Operation (356007)". Should you be interested in looking at either or both of these, and have any difficulty locating the files, then please contact us. We'd be happy to help.
