ACCES I/O Products (San Diego, CA) offers the Model USB-IIRO-16, featuring 16 Form C (SPDT) electromechanical relays and 16 optically isolated digital inputs. The board is designed to meet the needs of industrial systems monitoring and control. The industrial I/O market commonly uses electromechanical Form C relays due to their robustness and ability to withstand unexpected surge currents, allowing for increased flexibility in switching capability. These relays also are used where small reed relays are inadequate due to their susceptibility to contact damage.Designed as a portable, embedded solution for digital monitoring and control in any PC or embedded system with a USB 2.0 port, the unit contains an internal, removable screw termination board with onboard removable screw terminals to simplify wiring connections. Like the company’s PC/104 and PCI versions, the USB-IIRO-16 is designed for applications where onboard relays are required and inputs must be isolated such as in test equipment, instrumentation, and process control.
