Application

This module is typically used for signal amplification and electrical isolation in control cabinets. It is ideal for switching AC or DC loads such as motors, contactors, solenoid valves, and lamps, based on low-power 24V DC signals from a PLC’s digital output card.

Country of Origin

Manufactured in Germany.

CO2 Impact

Opting for this pre-owned module over a new one avoids the emission of approximately 14 kg of CO2, which is comparable to the emissions of a 70 km car journey. This promotes sustainable industrial maintenance.

FAQ

What is the maximum switching current for this module?

While the individual Schrack relays are rated for 16A (AC1), the Phoenix Contact module as a whole is specified for a maximum continuous current of 10A per channel. It is crucial to adhere to the module’s specification for safe operation.

Is this module compatible with modern PLCs?

Yes, electrically it is compatible. The module operates on a standard 24V DC signal. The primary considerations are physical connection (screw terminals vs. modern connectors) and ensuring you have the correct wiring from your PLC output card to the module’s input terminals.

Can I replace a single faulty relay on this board?

Yes, one of the main advantages of this design is the use of pluggable relays. You can individually replace a faulty relay (Schrack RP310024 or equivalent) without needing to replace the entire module, making maintenance cost-effective.
