The SER 4100 events recording system is a versatile high speed distributed microprocessor-based data acquisition system designed to monitor and record, in real time, changes of state of customer supplied field inputs with an accuracy of one millisecond.
A reliable source of time stamped events data for analysis: The SERs extensive communications facilities make it especially valuable as front end instrumentation for reducing burden on the main control systems computer.
Easy to program and use: Programming and operating the SER 4100 is simple. All communications are achieved by means of a keyboard terminal device for equipment configuration and operator reports.
A unique variable debounce filter system
Distributed sequential memory storage: The SER 4100s distributed sequential memory is capable of storing over 4500 event messages per 64 points on each scanner card.
Seven I/O Ports enable communication flexibility: The real value of the SER 4100 lies in its extensive facilities for communicating with a true diversity of other instrumentation. Paramount is its ability to provide relief for a main control computer, which makes it a valuable front end device.
Maintain system reliability and security: In developing the SER 4100, Qualitrol have paid careful attention to the kind of details necessary to fully protect the integrity of events data.
Combine events recording with annunciation:
While the SER 4100 is a system unto itself, it can also be used in conjunction with two types of annunciators. Either combination forms a powerful and complete system of events recording and visual and audible annunciation. The diagrams below show typical SER/1500 annunciator configurations. Many other configurations are available, depending upon customer requirements.

The SER 4100 is a complete events recording system for medium to large scale plant monitoring applications.
