4. Functionality
The PRY-32(PC) functions as a digital output interface board that uses Photo MOS relays to switch external AC or DC loads under software control. Each output channel acts as an independent solid-state relay, capable of switching both resistive and inductive loads within the rated voltage and current limits.
Operating Principle:
Each channel’s control signal from the host PC activates an internal opto-isolated driver circuit, which in turn triggers the Photo MOS relay. The relay closes or opens the circuit to the external load without mechanical contact, ensuring silent and wear-free operation.
Use Cases and Applications:
- Industrial automation and process control systems
- Test and measurement equipment requiring isolated signal switching
- PLC and SCADA system expansion
- Signal routing and multiplexing in laboratory environments
- Control of solenoids, lamps, indicators, and low-power actuators
- Replacement of mechanical relay boards for improved reliability
Compatibility:
The PRY-32(PC) is compatible with CONTEC’s range of interface cables and terminal blocks, allowing easy connection to sensors, actuators, and control devices. It integrates seamlessly with CONTEC’s software ecosystem, including Windows and Linux drivers and LabVIEW libraries.
