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.
BN 5983.53 with External Contactors This diagram shows how external contactors with positive guided contacts C1 and C2 may be used to reinforce the switching capacity of BN 5983 with continued redundancy.

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).
Indication
A2 14 24 34 54 42 (-)
The relay is equipped with two green LEDs. When illuminated they indicate the healthy condition of circuits K2 and K3.

Additional Information
Dimensions
If additional switching contacts are required then Relay BN 5983 may be used with extension module Type BN 3081 (diag. 7). Should a delayed release contact be required then BN 5983 may be used with time delay modules BG 7925 / IL 7824 / IN 7824 / BA 7924 (see below). Model BN 5983 and /101 may be used with protective guards/screens, but for this application reference is made to the dedicated gate monitors Model BD 5985 - BN 5986 shown on page 53 - 54. Gold plated contacts are available as an optional extra should very low switching currents be required. www..com If single channel high voltage AC pushbutton control is required (Risk Level 2) terminals S11, S12 - S22 should be linked and the Emergency Stop pushbuttons connected in series with terminal A1. (see also BN 5930/204).
