THERMAL MANAGEMENT SOLUTIONS
EN-DigiTraceE507SLS-IM-H56913 01/13
DESCRIPTION
The E507S-LS thermostat is designed for controlling heat-tracing
systems in hazardous locations. The E507S-LS can be used to
control heat-tracing circuits in a pipe-sensing mode (see Figure 1
on back page), to indicate low-temperature (see Figure 2) or high-
temperature (see Figure 3) alarm conditions, or to control the coil
on a contactor (see Figure 4).
