The Commander SR100B 100 mm strip-chart process recorder was launched in September 1996. It enabled recording of 1, 2, 3 or 6 inputs, could be equipped with up to 6 relay outputs and had an inbuilt text printing functionality.
The SR100B became obsolete in January 2015. Its ideal replacement is the ScreenMaster SM500F. This field-mount paperless recorder has up to 7 inputs, a 21 CFR part 11 compliant data recording system together and a clear text display. The SM500F also features a single relay output with up to 2 more available as an option.
For larger I/O requirements, the ScreenMaster RVG200 is an ideal alternative.
