The COS-REL8/16 is available in versions with 8 or 16 outputs and can be selected between the versions relay 3A or relay 5A. It can be operated as a stand-alone device as well as in combination with several COS modules. Due to the CANopen profiles according to the CiA® specification CiA 301, CiA 305 and CiA 401, this module is ideally suited for almost all applications in modern automation technology.

Relays 3A / 5A
Power relays with normally open (NO) function are used as digital outputs. They are suitable for switching capacities up to 5A and have a life time of up to 10 million switching cycles. The galvanic separation between input and output circuit is up to 3kV.
The baud rate (up to 1Mbit/s) and the node number of the module can be configured via coding switches. Alternatively, this configuration can also be carried out conveniently via LSS using a CANopen master in the bus.
The transmission can be optionally event-controlled, cyclic or synchronous. Thus, for example, digital input statuses can be sent to other BUS participants every second and additionally in the event of an input status change.
Dynamic PDO mapping also allows different types of measurement data to be sent in one PDO (e.g. analog and digital states).
Other nodes in the bus can be monitored via the heartbeat protocol. Each node cyclically sends a CAN message (heartbeat). If the message of a node is missing, e.g. due to a connection termination, this error is registered by the module and can switch an alarm, for example.
Easy installation thanks to DIN rail bus
Thanks to the practical COS bus connector, which is clipped into the top-hat rail, individual modules within a network can be very easily added or exchanged. CAN communication and the power supply is passed on to all connected modules via the DIN rail bus.
At the front side of our COS modules there is a row of status LEDs. These give you a quick overview of the most important functions of the modules, such as the switching states of the individual I/Os, module status or whether clean communication via the DIN rail bus is possible. This can be very helpful for fast error analysis, especially for field applications.
A screwless system from the manufacturer WAGO Kontakttechnik is used as the connector. The 1-wire female connectors are 100% protected against mismating and have an eject and locking mechanism. All conductor types up to 1.5mm² can be connected.
