Zero input option
In the TB135x-I version the repeater provides for the possibility, through a contact closure, to
zeroing the reading.
The function is lost with the shutdown of the equipment.
There are not effects of loss of safety function in case of load limiting systems (zero being carried
out only locally on the repeater).
The input is active on the rising and falling edge.
The closing of contact should be made with voltage-free contact.
The connections to the data connector are modified if compared to the standard version and are
showed in the table here below.
