9.29 Sensor Switch Box SSB-SND40
With help of the switch box two eddy current sensors, leakage flux sensors or combination sensors
can be connected with the SND40 control unit. Measuring via the switch box is always done by
selection resp. sequentially.
Switching over to another sensor is exclusively controlled by the PLC. The SND40 does not receive
any information about the selected sensor, thus the switch-over may only happen during the
measuring pause. Depending on type of sensor and task, the PLC must perform an additional
program switching on the SND40. This must be considered on planning the arrangement.
A 24V input serves for controlling the switch-over function.
The sensor cables are connected at corresponding flange sockets.
The allocated cables SKNS8S and SM18CECM18S-GG need to be ordered separately.
The PLC control cable is connected to a M12 flange socket.
The control cable is a part of the allocated machine and does not belong to the scope of supply.
