| | Input/Output Sepcifications |
 | | The input and output characteristics are critical to the proper operation, installation, reliability, and maintenance ease of the system. |
 | | Digital Inputs: Sequence of Events and Status DI Digital inputs are optically isolated, with at least 3.0 kV of isolation. |
 | | For optimum noise immunity, the detected transition level for 125 Vdc inputs should be in the range of 90 to 100 Vdc, for 48 Vdc inputs, the transition point should be approximately 29 volts, and for 24 Vdc inputs, the transition point should be approximately 19.5 volts. |
