Terminals MX2-V2 Item Terminal symbol Terminal name Description Specifications Digital Power supply SC Input signal common Common terminal for the internal power supply, digital input, and analog I/O terminals. P24 Input signal power supply This is 24-VDC power supply for contact input signal. For source logic input, this terminal functions as the common terminal. Allowable current: 100 mA max. P24S Safety input signal power supply 24-VDC power supply for safety switch contact input signals. It supports the source logic only. Allowable current: 100 mA max. PSC Input terminal power supply For sink logic input: Short-circuited to P24 For source logic input:
Short-circuited to SC To activate contact input via an external power supply, remove the short-circuit bar. For details on the connection, refer to Multi-function Input Terminals and Programmable Controller Connection on page 2-39. CMS Safety input signal com- mon Common terminal for the safety input terminals. Input S7 S6 S5 S4 S3 S2 S1 Multi- function input Select seven functions from among 66 functions, and allocate them to terminals S1 to S7. These terminals support both the sink logic and the source logic. For details on the connection, refer to Multi-function Input Terminals and Programmable Controller Connection on page 2-39.
