Product Information

Full details

This Phoenix Contact 2903315 relay module is designed for industrial control and automation applications, offering a reliable interface between control signals and power circuits. It's ideal for engineers and technicians who need to switch higher loads with low-voltage DC control signals. A key benefit is its compact, DIN rail mountable design with push-in connections for quick and secure wiring. One caveat is its specific 24V DC coil voltage, requiring proper power supply matching.

FAQs

What type of connection technology does this relay module use?

This relay module features push-in connection technology for fast and tool-free wiring.

What is the coil voltage for this relay?

The coil voltage for this relay module is 24V DC.

How many switching contacts does this relay have, and what type are they?

It has 2 changeover (CO) contacts, also known as DPDT (Double Pole Double Throw).

Can this relay be mounted on any type of rail?

No, it is designed specifically for mounting on a standard 35mm DIN rail.

What is the operating temperature range?

The operating temperature range is from -40°C to +60°C.

Does this relay have an indicator light?

Yes, it features an integrated LED status indicator to show when the coil is energized.

What is the maximum voltage and current the contacts can switch?

The contacts are rated for 250V AC/DC. The nominal current is not explicitly stated for the load side, but typically for such relays, it's around 6A or higher resistive load. Always refer to the datasheet for precise load current ratings.

Troubleshooting

Relay does not energize when control voltage is applied

Verify the 24V DC control voltage is present and correctly wired to the coil terminals. Check for proper polarity. Ensure the LED indicator is illuminated when voltage is applied.

Contacts are not switching loads

Confirm the relay coil is energized (check LED indicator). Ensure the load circuit is correctly wired to the contact terminals and the load itself is functional. Check for proper contact configuration (NO/NC).

LED indicator is not lit

Check the 24V DC power supply and wiring to the relay coil. Ensure correct polarity. If the problem persists, the relay may be faulty.

Intermittent operation or chatter

Ensure the control voltage is stable and within the specified range. Check for loose wiring connections. Extreme temperatures can affect performance; verify operation within the specified temperature range.

Pros and Cons

Pros

  • Fast and secure wiring with push-in connectors.
  • Space-saving, compact design for control cabinets.
  • Integrated LED for easy status monitoring.
  • Durable with built-in surge protection and long mechanical life.
  • Versatile switching with 2 CO contacts.

Cons

  • Requires a specific 24V DC power supply.
  • Not suitable for applications requiring AC coil voltage.
  • IP20 degree of protection limits use in harsh environments without additional enclosure.
  • No forced-guided contacts, which might be required for certain safety applications.

Setup, Compatibility & Care

Setup:

  1. Mount the relay module onto a standard 35mm DIN rail.
  2. Connect the 24V DC control voltage to the appropriate terminals on the relay base. Ensure correct polarity.
  3. Connect the load circuits to the switching contacts (terminals for the 2 CO contacts).
  4. Use solid or finely stranded wire with ferrules for the push-in connections. Push the wire firmly until it's securely seated.

Compatibility:

  • Control Voltage: Requires a stable 24V DC power supply. Ensure the supply can handle the coil resistance (640Ω) and current draw.
  • Mounting: Designed for 35mm DIN rail mounting.
  • Environment: Suitable for dry, indoor industrial environments (IP20 rated).

Care:

  • Keep the module clean and free from dust and debris. A dry or slightly damp cloth can be used for cleaning; avoid solvents.
  • Ensure proper ventilation around the module to prevent overheating, especially in enclosed cabinets.
  • Periodically check wiring connections to ensure they remain secure.
