MODEL FL646 THERMOCOUPLE ISOLATION AMPLIFIER (OBSOLETE)
Description
The Model FL646 Thermocouple Isolation Amplifier provides signal conditioning for a millivolt input from a thermocouple temperature probe. The input is isolated from the output for voltage differentials up to 1000VDC. The unit is designed to be mechanically and electrically compatible with Encore’s other Flexi-line DIN-rail mounted instrumentation.
