    The Model 7100S is a new range of economic solid state contactors for use with low temperature coefficient resistive loads. This unit features integral heatsinks with AC or DC logic inputs for fast switching that reduces thermal cycling of the heating elements resulting in longer element life. Options include Gross Fault (GRF) and Diagnostic Load Failure (DLF).  GRF indicates when a shorted device or an open load is detected. Similar to GRF, DLF detects a shorted device, an open load and partial load failure. There are no mechanical contacts to wear out and so maintenance costs and downtime are reduced. Silent operation and lack of electrical interference achieved by zero voltage switching give environmentally friendly operation.
