POINT I/O Module Data 97
Digital AC Input Modules
The 1734 digital AC input modules feature the following:
• 120 or 220V AC nominal are AC inputs
• Input range of 65…132 for 120V AC inputs; 159…264 for 220V AC
inputs
• Two sinking style inputs
• Autobaud (will match baud of existing devices on the network)
• Selectable input filter times (0…65 ms with 1 ms default)
• Sequential auto addressing
I/O messages are sent to (consumed) and received from (produced) these
POINT I/O modules. These messages are mapped into the processor memory.
