1-4 BE1-49 General Information
SPECIFICATIONS
Sensing Method Four wire, using a remotely installed 10 ohm copper or
100 ohm platinum resistive temperature detector (RTD)
located within the protected machine. Relay supplies
constant 40 mA current and senses voltage across the
temperature sensitive resistance element.
Outputs
Resistive
Inductive
Output contacts are rated as follows.
120/240 Vac - make 30 A for 0.2 seconds, carry 7 A
continuously, break 7 A. 250 Vdc - make and carry 30 A
for 0.2 seconds, carry 7 A continuously, break 0.1 A. 500
Vdc - make and carry 15 A for 0.2 seconds, carry 7 A
continuously, break 0.1 A.
120/240 Vac, 125 Vdc, 250 Vdc - break 0.1 A (L/R = 0.04).
Power Supply One of the six types of power supplies listed in Table 1-2
may be selected to provide internal relay operating power.

Type D power supply initially requires 14 Vdc to begin operating. Once operating,
the voltage may be reduced to 12 Vdc and operation will continue.
† Prior to 1996, Type E power supply accepted only ac input power. See the power
supply discussion in Section 3, Functional Description .
Target Indicator A magnetically latched, manually reset, target indicator is
optionally available to indicate that the output has tripped.
An internally operated or current operated target may be
specified. A current operated target requires 0.2 A in the
output trip circuit to actuate, and trip circuit current must
not exceed 30 A for 0.2 seconds, 7 A for 2 minutes, and 3
A continuous. A current operated target may be selected
only when normally open (NO) output contacts have been
specified.
