Input capacitance
All digital inputs are galvanically isolated from the supply voltage (PELV) and other high-voltage terminals.
1)
Terminals 27 and 29 can also be programmed as output.
2) Except Safe Torque Off input Terminal 37.
3)
See for further information about terminal 37 and Safe Torque Off.
4)
When using a contactor with a DC coil inside in combination with Safe Torque Off, it is important to make a return way for the
current from the coil when turning it off. This can be done by using a freewheel diode (or, alternatively, a 30 or 50 V MOV for quicker
response time) across the coil. Typical contactors can be bought with this diode.
