Figure 3-3: USB-67230 Isolated Input Figure 3-4: USB-67250 Isolated Input Change of State (COS) Detection COS (Change of State) refers to input state (logic level) changing from low to high or vice versa, wherein the COS detection circuit registers the edge of the level change.
In the USB-67230/67250, the COS detection circuit is applied to all DI channels, with the channel(s) to enable COS detection selectable by software. When an enabled channel changes logic level, the COS detec- tion circuit generates an interrupt request to the USB microcontroller, which, when detected, latches corresponding DI data into the COS latch register.

The frequency counter cal- culates base clocks occurring within a period (rising edge to rising edge or falling edge to falling edge) of the repetitive input signal, which is then converted to frequency value.

By default, when enabled, the input channel ignores signal changes from one state to another when not remaining in the state for a pre-defined period. The digital filter function is applied on all DI channels and counters, with the default setting disabled.
The DO output status is saved in the USB microcontroller and can be read back if necessary. The USB-67230 also features programmable power-up output status,allowing output in a known state when powered on. When the module is powered off (ejected from the USB port), all digital output reverts to OFF.
Relay Output (USB-67250 only) USB-67250 provides Form C and Form A relays, with channels 0 to 3 Form C, and 4 to 7 form A, as shown. Figure 3-12: Form C Relay Figure 3-13: Form A Relay Form C relays have NC (Normal Close), NO (Normal Open), and COM (Common) contacts.
