Setting the Terminal Block for Voltage Input (TBSI)

The Safety Controller provides dedicated safety inputs (SI1, SI2, SI3, SI4) to connect safety signals with test pulses.

The Protective Device has the output to send the signal to a machine such as a robot when it detects a hazadous situation.

The Protective Device may also include a test pulse in the signal to verify that the output function of this signal is working properly, in which case this dedicated safety input can be used.

Note

Each port of the TBSI terminal accepts a maximum of one test pulse of 1 ms every 20 ms.
The test pulses are allowed only for the Low active signal (normally High and switches to Low when an event occurs) among the Safety Input signals.
