Emergency Stop Relay Type BN 5983 complies fully with the
requirements of the Standard Specifications referred to on page 3 of
this Publication. The unit is housed in a compact 100mm wide case
suitable for DIN rail mounting and is available in a wide range of
auxiliary voltages. BN 5983.53/101 has a one second delay on reset, a
useful feature when using this relay as a combined Emergency Stop/gate
monitor. These relays are extensively used and specified by the UK/
European automotive industry.
Relay BN 5983 operates on the principle described on page 6 of this catalogue.
The OFF and the EMERGENCY STOP buttons are connected in series between
terminals S11 and S12/S22. The On/Reset button is
connected between terminals S12 and X4. The auxiliary supply is
connected to terminals A1(+) and A2(–).
The circuits to be tripped may be connected to terminals 13-14,
23-24 and 33-34. Remote signalling circuitry, if applicable, is
connected to terminals 41-42, 53-54.
For additional security an insulation monitoring relay may be
connected to monitor terminal PE(-) to ground. (Relay details on request).
This relay is suitable for category 3 applications.
It is recommended that redundancy is carried through to the
EMERGENCY STOP button by using a dual contact button as shown.
If a single contact button is used then terminals S12 and S22 should
be bridged (category 2 applications only).
The relay is equipped with two green LEDs. When illuminated they
indicate the healthy condition of circuits K2 and K3.
