The LFE series controllers were supplied primarily with the T300, T400 and some T500 series thermal platform systems starting in late 1987 until about 1997. The vast majority of them were model 2000 and model 2010 controllers with a small number of the very sophisticated model 3000. All of the LFE models were ÂµP based digital indicating controllers with vacuum fluorescent (VF) display and were available with optional RS-232 and GPIB-488 communications interfaces. The model 2010 added a programmable ramp & soak feature. The LFE model 3000 controller added a 10-key numeric data entry keypad in addition to the traditional data entry keys and a large bit-addressable graphical VF display.
