Product Information

Full details

The Finder 4C.01.9.024.0050 is an industrial interface relay module designed for control and automation applications. It is ideal for engineers and technicians who need reliable switching of electrical loads up to 16A. A potential caveat is its specific 24V DC coil voltage requirement, which must match the control circuit. Key features include a single changeover contact (1CO), screw terminals, an LED status indicator, and an integrated flyback diode for protection.

Extended Product Information

FAQs

What is the coil voltage for this relay?

The coil voltage for the Finder 4C.01.9.024.0050 is 24V DC.

What is the maximum switching current and voltage?

The relay can switch a maximum of 16A at 250VAC.

Does this module include a socket?

Yes, the product is supplied complete with a socket, relay, module, and retaining clip.

How is the relay mounted?

It is designed for standard 35mm DIN rail mounting.

What does the LED indicator signify?

The LED indicator shows the status of the relay coil; it is typically lit when the coil is energized.

What is the contact configuration?

This module features a single changeover contact (1CO).

Is there protection against voltage spikes?

Yes, it includes an integrated flyback diode to protect the control circuit from voltage spikes when the coil is de-energized.

Troubleshooting

Relay does not switch when coil is energized.

Verify the 24V DC control voltage is correctly applied to the coil terminals (A1/A2) and that the polarity is correct. Check that the input current is sufficient (at least 20mA). Ensure the LED indicator lights up when the coil is energized.

Contacts are welded or not making connection.

Check that the load current and voltage do not exceed the 16A/250VAC rating. Inspect contacts for signs of damage or arcing. If welded, the relay likely needs replacement.

LED indicator is not lit.

Confirm the 24V DC coil voltage is present and correctly connected. The LED might be faulty, or the relay coil could be open-circuit. Check continuity of the coil.

Overheating of terminals.

Ensure wires are properly sized for the load current and are securely tightened in the screw terminals. Overloading the contacts can cause overheating.

Pros and Cons

Pros

  • Robust construction suitable for industrial environments.
  • Integrated status LED simplifies monitoring.
  • Built-in flyback diode protects control circuitry.
  • Standard DIN rail mounting ensures easy installation.
  • Reliable switching performance for its class.

Cons

  • Requires a specific 24V DC power supply for the coil.
  • Single changeover contact limits complex switching scenarios.
  • IP20 protection rating means it's not suitable for dusty or wet environments without additional enclosure.

Setup, Compatibility & Care

Setup:

  1. Mounting: Securely attach the relay module and its socket to a standard 35mm DIN rail.
  2. Wiring: Connect the control circuit to the coil terminals (A1/A2) ensuring correct polarity for the 24V DC supply. Wire the load circuit to the output contacts (11, 12, 14).
  3. Power Up: Apply the 24V DC control voltage to the coil.

Compatibility:

  • Control Voltage: Requires a stable 24V DC power source. Ensure the power supply can provide at least 20mA.
  • Load Voltage/Current: Compatible with AC loads up to 250V and 16A, or DC loads within specified limits (consult datasheet for DC load specifics).
  • Environment: Suitable for dry, indoor environments with minimal dust and vibration (IP20).

Care:

  • Keep the module clean and free from dust and debris. Use a dry cloth for cleaning; avoid solvents.
  • Ensure all wiring connections remain tight. Periodically check for signs of wear or overheating.
  • Avoid exposing the module to excessive moisture or extreme temperatures outside its operating range.
