2.8 Digital Input & Output (Slim SKU only)
Only U-BPC Slim version supports DI/O channels designated DI0~DI8 & DO0 ~ DO8.The connector type
is a plug-in screw terminal block that enables you to connect to field I/O devices directly without
additional accessories. Whether the high voltage range is the triggering mode or normal mode
depends on the design of the device. Quite often the logic level 1 (high voltage) is used to indicate the
triggered event, but not always. The following sections descript the technical data of DI/O. Before
starting using DI/O, ensure to check the connection type of your DI/O devices to connect.
