Product Information
Full details
This Finder 39 Series Interface Relay Module is designed for electricians and automation engineers needing precise control and reliable switching in industrial applications. Its key benefit is its multifunctionality with 8 time functions and 8 time ranges, offering flexibility in complex timing sequences. A potential caveat is the need for the user to acquire and install a separate microfuse for certain configurations.

Extended Product Information
FAQs
What is the input voltage range for the coil?
The coil operates with 24V ac/dc, with a minimum input voltage of 19.2V ac/dc and a maximum input voltage of 26.4V ac/dc.
How are the time functions and ranges selected?
Time functions and ranges are selected using the DIP switches located on the module. There are 8 time functions and 4 time ranges available, up to 6 hours.
Do I need to supply a fuse for this module?
If you are using the optional output fuse module for protection, you must acquire and install a compatible microfuse (5 x 20 mm) yourself. The fuse is not included with the module.
What type of contacts does this relay have?
This module features Single Pole Double Throw (SPDT) contacts.
What is the maximum switching voltage?
The switching voltage for the contacts is between 250-400V ac.
What are the physical dimensions of the module?
The module dimensions are approximately 6.2mm in length, 90.7mm in depth, and 94.3mm in height.
Can I bridge terminals A1 or A2 and 15?
Yes, terminals A1 or A2 and 15 can be bridged for specific wiring configurations as indicated in the technical documentation.
Troubleshooting
Relay does not activate
Verify that the coil voltage (24V ac/dc) is correctly applied to terminals A1/A2 and is within the operating range (19.2V - 26.4V ac/dc). Check DIP switch settings for intended function.
Timing is inaccurate
Ensure the DIP switches are set correctly for the desired time function and range. Use the fine-tuning adjustment for precise timing if needed. Check for environmental factors like temperature fluctuations.
LED indicator is off
Confirm power supply to the coil. If power is present and the LED is still off, the module may require replacement.
Contacts are not switching
Check if the load voltage is within the specified switching voltage limits (250-400V ac). Ensure the coil is energized and the relay is receiving the correct control signal.
Pros and Cons
Pros
- Versatile multifunction timer with multiple time functions and ranges.
- Compact design suitable for DIN rail mounting, saving panel space.
- Clear LED indicator for operational status.
- Supports fine-tuning of time settings for precision.
- Optional fuse module enhances protection and fault diagnosis.
Cons
- Microfuse is not included and must be purchased separately.
- Operating temperature range is limited to -20°C to +50°C.
- Requires careful selection of input voltage (19.2V to 26.4V ac/dc).
Setup, Compatibility & Care
Setup: The module is designed for DIN rail mounting. Connect the power supply to the appropriate coil terminals (A1/A2) and the control signals to the input terminals. Terminals A1 or A2 and 15 can be bridged for specific configurations. If using the optional output fuse module, ensure a compatible microfuse (5 x 20 mm) is correctly installed in the designated slot. Settings for the time functions and ranges are adjusted using the DIP switches on the module.
Compatibility: This module is compatible with control systems providing a 24V ac/dc power supply within the specified input voltage range (19.2V to 26.4V ac/dc). The SPDT contacts are suitable for switching loads up to 250-400V ac. Ensure the ambient operating temperature remains within the -20°C to +50°C range for optimal performance.
Care: Keep the module clean and free from dust and moisture. Ensure proper ventilation around the module, especially when installed in a control panel. Periodically check all connections for tightness. Inspect the fuse (if installed) through the visible window for any signs of failure.
