    If you cannot be absolutely certain of avoiding these situations, you are safer limiting the relay outputs of the PDISO-8 to switching control voltage circuits (5 to 24V slave relays or contactors for switching line power circuits).

    Relay Output register, de-energizing all relays. This event provides a defined state at power up. A soft boot of the computer ([Ctrl] + [Alt] + [Delete]) does not produce a hardware reset of the PDISO-8; thus, the state of the relays is unchanged by soft booting the computer.

  • Page 45: Ac Input

    Each input channel is provided with a switchable response filter. This is a single-pole filter with a time constant of about 5ms. You must use this filter when handling AC inputs, as these inputs periodically pass through zero at the voltage crossings, and the logic output is not sustained at these instants, as shown in Figure 4-7.
