Open-collector outputs and isolated inputs address distributed control

摘要

The Seal/O-530 and SeaI/O-540 DAQ Modules integrate open-collector outputs and optically isolated inputs for distributed control. Ordering options allow control from a host device via wireless, Ethernet, RS-485, USB, or RS-232. Up to 247 modules can be daisy chained. The Seal/O-540's 32 open-collector outputs control common industrial peripherals, and each output circuit includes a flyback diode for protection when interfacing highly inductive loads.
