Product Information

Full details

This Finder 4C Series Interface Relay Module is designed for industrial control and automation applications requiring reliable signal switching. It offers a robust solution for interfacing control signals with actuators, particularly in systems using 24V ac control voltages. A key benefit is its compact size and DIN rail mounting capability, simplifying integration into control panels. However, users should note that this module operates specifically with a 24V ac coil, requiring careful attention to power supply compatibility.

Extended Product Information

FAQs

What is the coil voltage for this Finder 4C Series relay?

This specific model, 4C.01.8.024.0060SPA, operates with a 24V AC coil voltage.

What type of contact configuration does this relay have?

It features a Single Pole Double Throw (SPDT) contact configuration, meaning it has one common terminal, one normally open (NO) terminal, and one normally closed (NC) terminal.

Can I use this relay with a 24V DC power supply?

No, this module is designed exclusively for 24V AC coil operation. Using DC voltage will not function and may damage the relay.

How is this relay mounted?

It is designed for standard 35 mm DIN rail mounting (EN 60715).

What is the operating temperature range?

The relay can operate reliably in temperatures ranging from -40°C to +70°C.

What is the contact material?

The contact material is Silver Alloy, chosen for its good conductivity and durability.

What are the dimensions of the module?

The dimensions are 81mm in length, 15.8mm in width, and 64.6mm in height.

Troubleshooting

Relay does not energize when 24V ac is applied to the coil.

Verify that the power source is indeed 24V ac and is correctly connected to the coil terminals (A1, A2). Check for any breaks in the wiring. Ensure the input current is sufficient (45mA) and the coil resistance (320Ω) is within expected parameters.

Contacts do not switch (no continuity change when coil is energized).

Confirm the coil is receiving the correct voltage. Check if the load connected to the contacts is within the relay's rated capacity. Inspect the contacts for any signs of damage or contamination.

Relay chatters or switches intermittently.

Ensure a stable and clean 24V ac power supply to the coil. Fluctuations in voltage can cause erratic behavior. Check for any potential electromagnetic interference in the vicinity.

Incorrect switching (e.g., NO contact is open when it should be closed).

Double-check the wiring of the NO, NC, and common terminals against the intended circuit design. Ensure the relay is functioning correctly for its SPDT configuration.

Pros and Cons

Pros

  • Compact and space-saving design.
  • Easy and secure DIN rail mounting.
  • Suitable for a wide range of industrial operating temperatures.
  • Reliable Silver Alloy contact material.
  • Flexible SPDT switching capability.

Cons

  • Strictly operates with 24V ac coil; not compatible with DC or other AC voltages.
  • Single channel switching only (SPDT).
  • Screw terminals may require specific tools for secure tightening.

Setup, Compatibility & Care

Setup:

  1. Mounting: Securely attach the relay module to a 35 mm DIN rail by snapping it into place. Ensure it is firmly seated.
  2. Wiring: Connect the control signal (24V ac) to the coil terminals (typically marked A1 and A2). Connect the device to be switched to the common (3), normally open (1), and normally closed (5) terminals, respecting the SPDT configuration.
  3. Verification: Double-check all wiring connections for accuracy and tightness before applying power.

Compatibility:

  • Coil Voltage: This module is exclusively designed for a 24V ac coil voltage. Do not apply DC voltage or AC voltages other than 24V.
  • Mounting: Compatible with standard 35 mm DIN rails (EN 60715).
  • Contact Rating: Ensure the load you are switching is within the current and voltage limits of the relay's contacts.

Care:

  • Environment: Avoid exposing the module to excessive dust, moisture, or corrosive atmospheres. While it has a wide operating temperature range, extreme conditions can affect longevity.
  • Cleaning: If cleaning is necessary, disconnect all power and use a dry or slightly damp cloth. Do not use solvents or abrasive cleaners.
