SECTION 1 • GENERAL INFORMATION
GENERAL
The BE1-49 Temperature Relay is a solid-state device that monitors the temperature of a remotely located
resistivetemperaturedetector(RTD),andprovidessignalstotheprotectiveschemewhenthesensedtemperature
goes above or below predetermined limits. A variety of output options provide a selection of latching or non-
latching types of normally open or closed contacts.
DESCRIPTION
The Basler Temperature Relay supplies a constant current to a remotely located resistive temperature detector,
and senses the temperature of the detector by measuring the voltage across the resistive element. When a pre-
programmed temperature limit is reached, the relay energizes its output relay so that the protection scheme may
take appropriate action.
Programming of the temperature limits is accomplished by adjusting the UPPER TEMPERATURE LIMIT and
LOWER TEMPERATURE LIMIT controls on the relay front panel. Each control is adjustable over a range of 60°
to 190°C. The effect on the protection scheme of exceeding the control setting limits of the relay is defined by the
output option selected. Table 1-1 shows the available output options. The dotted horizontal lines represent
hypothetical upper and lower temperature limit settings. The circled numbers represent relay case terminals.
A target that indicates when the upper temperature limit has been exceeded is optionally available, and may be
either internally operated or current operated. The current operated target requires a minimum of 0.1 A to flow in
the trip circuit for proper operation. The internally controlled target MUST be specified if NC output contacts are
specified.
The relay assembly is mounted in a drawout cradle and enclosed in a standard, utility style case. Individual circuit
components are accessible by removing the individual printed circuit boards from the relay cradle and using an
extender board (Basler part number 9 1655 00 100) to test or troubleshoot.
MODEL AND STYLE NUMBER
The electrical characteristics and optional features included in a particular model BE1-49 Temperature Relay are
defined by a combination of letters and numbers that make up its style number. The model number, followed by
its style number, appears on the front panel, drawout cradle, and inside the case assembly.
ThestylechartsrepresentedbyFigure1-1,listsallavailableoptionsandrelatesthemtothestylenumbersystem.
Upon receipt of a temperature relay, be sure to check relay style number against the requisition and packing list
to see that they agree.

SAMPLE STYLE NUMBER
The style number identification chart above illustrates the manner in which a relay's style number is determined.
For example, if the style number were P1J-A1E-B0N5F the device would have the following features.
(P) RTD sensing output
(1) Designed to be used with copper RTD rated 10 ohms at 25°C
(J) Two normally open primary outputs, with the upper temperature limit trip contact latching on closure
(A1) Instantaneous trip timing
(E) Isolated internal operating power obtained from 100/120 Vac or 48/125 Vdc source
(B) One current operated target
(0) No Option 1 available
(N) No Option 2 available
(5) SPDT auxiliary contact output
(F) Semi-flush mounting

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.

tType 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.
