2-2 Wiring „ Specifications of the Control Circuit Terminals 2 Design 2-22 Terminal symbol Terminal name and function Default setting Specifications Input signal PSC External power supply terminal for input signal (input).......................At sink logic Internal power supply output terminal for input signal (output)......At source logic ⎯ 24 V DC ±10% 30 mA max. 24 V DC ±10% 100 mA max. S1 Multi-function input terminals S1 to S5 Select 5 functions among the 31 functions and allocate them to from terminals S1 to S5. The terminal allocation is changed automatically when the emergency shutoff function is used. Refer to "Emergency Shutoff Input Function" (page 4-45).
