PT8DIO - 8 Digital Input/ Output Module
The PT8DIO module is an 8 channel digital input and 8 channel digital output module.
The inputs are isolated from the logic by bi-directional opto-couplers. The common is connected internally to either the -volts or +volts field power supply terminals using a jumper link which is situated inside the housing.
The inputs have internal counters associated with them. These counters are 32 bit counters allowing a count value from 0 to 4294967295. The count value can be cleared by writing a zero to the associated registers or preset to any other value using the same method.
Note: The count values are not battery backed-up and will be lost if power is turned off.
