The PT4RO module has four normally open/normally closed relay outputs. These modules can be used when higher drive capacity is required, or when isolation between the outputs is necessary.
Each output can be switched on or off individually, or all outputs can be set simultaneously by writing a single number to the output register that represents the status of all outputs.
An output watchdog timer can be configured to turn off all outputs if there has been no communication with the module for up to 255 seconds. A value of 0 seconds will disable this timer, and the outputs will remain in their last programmed state.
