ESM-CB-AZ-FI2-BR-IO-158875 (Order no. 158875)

Connection options

The following functions are possible given the corresponding wiring:

• Start input for automatic start or a monitored start button

• Monitoring of downstream relays or contactors (feedback loop)

• Short circuit monitoring to detect short circuits between the connecting cables and to shut down the outputs or prevent relay starting if necessary

• Earth fault/ground fault monitoring to detect short circuits between the connecting cables and earth or ground and to shut down the outputs or prevent relay starting if necessary.

Relay outputs

• The outputs are redundantly designed and electrically decoupled.

• Simultaneity monitoring of the safety outputs to monitor safety components over time.

• No time-delayed shutdown

Industry 4.0 ready

Process data are cyclically sent to the control system via IO-Link. These data include all status signals, such as the door or guard locking position, and the indication of whether a switch is in the limit range of the actuating range.

The process data are available to the control system after approx. 200 ms and can be used for the automation process.

Moreover, acyclical polling can be used to collect environmental data such as the internal switch temperature, the applied voltage or the ID of the transponder used, as well as other values.

Plug and Play series connection

• Connection for safety switches with BR technology without addressing the individual switches

• The wiring and configuration work is minimized.

Device data and events

The higher-level control system can poll more than 30 different items of information from the connected switches. Comprehensive data transmission via IO-Link enables targeted preventive maintenance, for example.

Simple implementation of innovative applications

Device data from the actuators used can be employed to detect individual rotary table positions or different containers, for example.
