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

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

The modulealso provides 16 Form C SPDT relay outputs rated at 30V dc at 2A capacity, or125V ac at 0.1A. Each relay has two sets of normally open, common, and normallyclosed contacts wired in parallel for greater reliability and lifetime.

Extendedtemperature operation of -40 to +85C is tested and guaranteed. Optional 0-ohmresistors may be installed instead of the address jumpers for additionalruggedness. Optional latching connectors may be installed for both inputs andoutputs to further improve reliability.

UniversalDriver works with Windows XP, CE, Linux, QNX and DOS. Application examples areincluded for each function and OS to provide a quick starting point fordevelopment.
