Approx. 4 kΩ
Safe Torque Off Terminal 37
3, 4)
(Terminal 37 is fixed PNP logic)
Voltage level 0–24 V DC
Voltage level, logic'0' PNP <4 V DC
Voltage level, logic'1' PNP >20 V DC
Maximum voltage on input 28 V DC
Typical input current at 24 V 50 mA rms
Typical input current at 20 V 60 mA rms

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 chapter 2.4.6.6 Terminal 37 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.
