Hi danibell, The permissible high voltage is 28.8V and 13-28.8 is the valid 1(High) range. So definitely u will need external signal conditioning circuit for proper signal status. |

Hello, Please revise again the technical specs of that CPU: https://support.industry.siemens.com/cs/us/en/pv/6ES7313-5BG04-0AB0/td In supply voltage section, the permissable range for voltage (feeding voltage of the CPU) is between 19.2 & 28.8 VDC. It doesn't mean at all the logic 1 of any digital signal. And Under section Digital input / Input voltage, Rated voltage: 24VDC For signal "0": -3 to +5VDC For signal "1": +15 to +30 VDC. |
