This module has 16 open collector (NPN) digital outputs. The outputs may be used to drive lamps or external relays when more drive capability is required.
The PM4RO module has 4 normally open/ normally closed relay outputs. These modules may be used when a higher drive capability is required, or when isolation between outputs are required.
The PMDAIO module is a multipurpose combination of inputs and outputs. The module can accommodate either 2 or 3 wire RTD sensors, current (0-20mA) and voltage (0-10V) inputs, current (0-20mA) or voltage (0-10V) output, and digital inputs and outputs.
The PMDAIO2 module is a multipurpose combination of inputs and outputs. The module can accommodate either current (0-20mA) or voltage (0-10V) inputs, current (0-20mA) outputs, and digital inputs and outputs.
