POINTBlock I/O Modules
Mount these 1734D input/output modules on DIN rail with an integrated
DeviceNet communication interface, 8 inputs and 8 outputs, removable
terminations, and a POINTBus expansion port.
The modules include a non-isolated DeviceNet communication interface. The
24V dc from the DeviceNet connection powers a non-isolated dc/dc
converter that generates +5V dc that powers the POINTBlock electronics and
connects to the POINTBus port to power the expansion I/O electronics.
