PRODUCT INFORMATION
Product Overview
The Allen-Bradley 1794-APBDPV1 is a FLEX I/O Profibus DP V1 Adaptor. It connects a FLEX I/O system to an external PROFIBUS DP network. The adapter operates across a DC voltage range of 19.2V DC to 31.2V DC. Nominal power supply input is rated at 24V DC with 385 mA maximum input current. The unit provides capacity for up to eight FLEX I/O modules on the backplane.
This adapter supplies up to 640 mA of output current to the local Flexbus. Network transmission rates reach up to 12 Mbits per second using standard drop cables. Power dissipation measures 4.2 W at 19.2V DC, producing 14 BTU per hour thermal dissipation. It includes a 9-pin D-shell connector and rotary thumbwheel switches for node addressing. Basic isolation provides 50V protection from the PROFIBUS line to the backplane and power circuits.
