MJB5 Plus Gateway |3Introduction
The modular junction box MJB5 Plus is designed for use together with OpenBus™ control boxes.
The MJB5 Plus makes it possible to connect multiple hand controls and attendant controls. It can even be
used for charging or to connect the Under Bed Light and 3rd party products.
The compact design and in-line cable management makes it easy to integrate in a wide range of healthcare
applications like hospital beds, surgery tables and treatment chairs.
The MJB5 Plus offers IPX6 Washable DURATM and is the perfect match for the OpenBus control box platform.
IPX6 Washable DURA helps prolong the lifetime and makes the system ready for wash tunnels and highpressure wash down.

MJB5 Plus versions 504-010 and 504-020
The MJB5 Plus is a simple gateway interface which can connect switch input
notifications from the hospital or nursing home infrastructure such as service/nurse
call systems.
Please note that notifications are only to be used as service information and not for
emergency issues.

Relay 1
Relay 1 is NO when connected to mains and NC when no mains, this means the relay is “active”, whenconnected to mains (closed loop). The closed loop principal is to ensure that a notification is sent if power ismissing on the bed. When mains is disconnected (power is missing), the relay will go from NO to NC which
will automatically result in a notification (status indicator) on the OpenBus.
Relay 1 can be activated via the patient control (Key1/Key4) or the attendant control (Key2 / Key3). Whena key is activated, the relay will switch state from NO to NC for 2 seconds. After 2 seconds the relay willautomatically change state from NC to NO.
The status of the relay is indicated on the OpenBus and can be used for switching on an LED.

NORelay 2
Relay 2 is by default NC, with or without mains, (open loop).
Relay 2 can be activated via the patient control (Key 1) or the attendant control (Key 2 / Key 3).
When the relay is activated, it will switch from NC to NO for 2 seconds. After 2 seconds the relay willautomatically change state from NO to NC.
The status of the relay is indicated on the OpenBus™ and can be used for switching on an LED.
By using the variant 504-020 will relay 2 be controlled by the MJB5 Plus variant 505/506 with switch input.
Notification 1 = Switch input S2 / notification 2 = Switch input S1
When using this combination, is it important to have the MJB5 Plus 505/506 connected to the system all thetime. If it is not connected, the Gateway MJB5 Plus will see it as a notification and the relay will be activated.
The Gateway MJB5 Plus is “scanning” the OpenBus system. every minute for a notification.
