Safety relay
JSBT5(T)
Approvals:
TÜV Nord
Safety relay for:
Emergency stop
Interlocked hatch
Features:
Single and “dual” channel
Test/start input
Width 22.5 mm
LED indication
3 NO/1NC relay outputs
Single channel safety relay
The JSBT5 is designed to connect safety devices, such as
emergency stops, directly in the voltage supply circuit to
the relay. Despite a maximum built-in width of 22.5 mm the
relay is very powerful.
With 3 NO safety outputs, 1 NC, test input and complete
internal supervising, the JSBT5 is quite unique. In addition
you can order delayed outputs (JSBT5T).
In order for the safety outputs to close, the supply voltage, e.g. by means of an emergency stop button, must be
connected to A1 and A2 and the test input closed. After
actuation of the relay the test input can be opened again.
The test input is intended to supervise that contactors
or valves have dropped/returned before a new start can
be permitted.The test input can also be used for starting
and the start button can be supervised (see connection
example on next page).

Safety level
The JSBT5 has a twin and supervised internal safety function. Power failure, internal component faults or external
interference cannot result in dangerous functions.
Input via A1 only is not protected from short circuiting,
and therefore installation is critical for the safety level to be
achieved. To achieve a higher safety level a screened cable can be used and/or connection made to both A1 and
A2 (see example overleaf).
Regulations and standards
The JSBT5 is designed and approved in accordance with
appropriate directives and standards. See technical data.

When supply voltage is connected to A1
and A2, relays K1 and K2 are activated.
K1 and K2 drop if the supply voltage is
disconnected. Both relays K1 and K2 must
drop for them to be activated again. Another
requirement is that the test circuit, X1 - X2,
must be closed for the outputs to be activated. Thereafter X1 - X2 can either be open
or constantly closed.
The supervising circuit ensures that both

K1 and K2 have dropped before they can
be reactivated. The stop function complies
with the requirement that a component fault
or external interference cannot lead to a
dangerous function.
The safety outputs consist of contacts
from K1 and K2 connected internally in
series across terminals 13 - 14, 23 - 24,
and 33 - 34. These contacts are used to
