Safe Torque O (STO) Terminal 37
1), 2)
(Terminal 37 is xed 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
Input capacitance 400 nF
All digital inputs are galvanically isolated from the supply voltage (PELV) and other high voltage terminals.

O.
2) When using a contactor with a DC coil with STO, always make a return path for the current from the coil when turning it o.
The return path can be made by using a freewheel diode across the coil. Alternatively, use a 30 V or 50 V MOV for quicker
response time. Typical contactors can be bought with this diode.
