PC/104 Optoisolated I/O Module Protects Embedded Computing Systems from Environmental Hazards

Opal-MM-1616-XT offers 16 unidirectional optoisolated inputs that can accept dc voltages up to 30V dc. Inputs feature channel to channel and input to output isolation of 500V dc or ac. The inputs also feature a programmable edge detection circuit (change of state detection circuit) that can generate interrupts on any change on any input.

The module also provides 16 Form C SPDT relay outputs rated at 30V dc at 2A capacity, or 125V ac at 0.1A. Each relay has two sets of normally open, common, and normally closed contacts wired in parallel for greater reliability and lifetime.

Extended temperature operation of -40 to +85C is tested and guaranteed. Optional 0-ohm resistors may be installed instead of the address jumpers for additional ruggedness. Optional latching connectors may be installed for both inputs and outputs to further improve reliability.

Universal Driver works with Windows XP, CE, Linux, QNX and DOS. Application examples are included for each function and OS to provide a quick starting point for development.
