BE1-49 Functional Description 3-3
Output Drivers
Two Darlington amplifiers are provided as output drivers in the relay. Each amplifier receives the output current
from an associated comparator and amplifies it to provide sufficient current to drive the selected output device.
An inverter is provided in the input to the lower limit output driver to cause it to energize the output relay when the
lower limit is exceeded.
Output Relay
A wide variety of relay contact arrangements are available. The contact arrangement is specified by the OUTPUT
letter in the relay style number. Refer to Figure 1-1 for a list of all of the available output options.
Target Indicator
An optional target indicator on the front panel is tripped and magnetically latched when the upper temperature limit
is exceeded. It may be reset manually after the upper temperature limit output is de-energized.
