The Mixed Input/Output (I/O) modules are part of the special module collection that deserve special mention. They provide a combination of features that satisfy the needs of many smaller sites. The Mixed I/O module provides eight digital inputs that are identical to those found on the 16DI module. There are also two 4-20 ma analog inputs that are quite similar to those found on the 8AI module, the difference being that 12 bit A/D converters are used which provide 1600 steps in the 800-4000 active range with ±0.1% accuracy (see Figure 10). Four relay outputs are also provided: two of the relays have Form A contacts and two relays have Form C contacts. The FRN1490 option provides a module with three magnetically-latched and one electrically-energized relays whereas the FRN1484 option provides a module with four electrically-energized relays. Both modules provide plug-in screw terminals for connection of the associated wires.
