DescriptionArcom SPIBB 40 Channel Parallel I/O Interface Board | Digital I/O Board
DescriptionArcom SPIBB 40-Channel Parallel I/O Expansion STEbus ModuleSPIBB provides a low-cost and versatile means of expanding the digital I/O of STEbus systems Two 8255 devices give 40 I/O lines; 32 lines are fully buffered with 24mA drive sink and 15mA source capability. Direction and enable are software-programmable, and 16 lines can be disabled at system power-up, for extra safety Jumpers select interrupt status, so the board can be set for any one of the STEbus' four attention request levels Digital I/O lines are taken out through the Signal Conditioning Bus interface, providing a second level of standardization to the STEbus. Any of Arcom's range of real-world interfaces including SSRs, open-collector outputs, mains detectors or opto-isolators, and prototyping boards, can be simply connected.Features: 40 I/O lines 32 buffered TTL lines 24mA sink, 15mA source capability Signal Conditioning Bus interface
