Why Choose the ABB OCB-1A Connection Box?
The ABB OCB-1A, reference 20-055-02 and order code 2TLA020055R3000, is a sensor connection box for serial connection of OSSD safety sensors. Part of ABB's safety accessories range, it simplifies machine-safety wiring by allowing multiple compatible sensors to be connected while requiring only one cable between the control cabinet and the sensor network.
The OCB-1A supports the connection of up to four Eden OSSD sensors with M12 8-pin connectors, as well as other compatible safety sensors. Safety signals are connected serially, while an individual information signal from each Eden sensor can be retained, providing a practical connection architecture for industrial safety systems.
Designed for 24 V DC systems, the OCB-1A uses M12 8-pin female connections for the sensors and an M12 8-pin male connection towards the control cabinet. Its IP67 degree of protection and compact housing make it suitable for installation directly on industrial machinery in demanding automation environments.
Key Advantages
- Connects up to four OSSD safety sensors through a compact connection box.
- Designed for serial connection of OSSD safety signals.
- Simplifies machine wiring by requiring only one cable from the control cabinet to the sensor network.
- Supports ABB Eden OSSD sensors and other compatible safety sensors.
- Provides an individual information signal from each Eden sensor.
- IP67 protection supports installation in demanding industrial environments.
Key Features
- ABB OCB-1A sensor connection box.
- Connection capacity for up to four safety sensors.
- Serial OSSD safety-signal connection.
- M12 8-pin female sensor connections.
- M12 8-pin male connection towards the control cabinet.
- 24 V DC rated supply voltage.
- IP67 degree of protection.
- Compatible with Eden OSSD sensors with suitable M12 8-pin connectivity.
- Unused OCB-1A sensor connectors require an ABB JSOP-8 termination plug.
Reliable Safety Sensor Connectivity for Industrial Machinery
Machine-safety systems can require several sensors distributed around guarding, access points and hazardous areas. The ABB OCB-1A reduces field cabling by providing a central connection point for up to four compatible OSSD safety sensors, with their safety signals connected in series and a single connection routed back towards the safety controller in the control cabinet.
The combination of M12 connectivity, individual information signals from Eden sensors and an IP67 housing makes the OCB-1A particularly suitable for decentralised machine wiring. Where fewer than four sensor ports are used, the unused connectors must be fitted with ABB JSOP-8 termination plugs to complete the intended connection arrangement.
Typical Applications
- ABB Eden OSSD safety sensor networks.
- Serial connection of compatible OSSD safety sensors.
- Machine guarding and access protection systems.
- Automated production and assembly machinery.
- Packaging and material handling equipment.
- Industrial safety-controller installations requiring simplified field wiring.
