» Functional Description
The PISO-725 provides 8-channel electric mechanical relay output and 8-channel digital input.
The digital input channels can be isolated or non-isolated that is selected by hardware jumpers.
All digital inputs can generate an interrupt if any state change occurs at any one or more of the inputs.
This is very useful when monitoring contact closures/ openings since continuously polling the input is not necessary.
All relays are de-energized at power-on. On/Off status of the relays can be read back.
The PISO-725 can be used in various applications including contact closure checking, external voltage sensing, and loading sensing and control and sensing applications.
