Product Information
Full details
The Metz Connect 110657 is a professional multifunction timer relay designed for electricians and automation engineers needing precise timing control in various applications. Its key benefit is the versatility offered by eight adjustable time ranges and five programmable modes, all managed through intuitive coding switches and a linear potentiometer. A minor caveat is that its compact size and screw terminals require careful installation in crowded control panels.

FAQs
What are the five programmable modes of this timer relay?
The five modes are: 1. On-delayed, 2. Off-delayed, 3. Making-pulse interval, 4. Flashing for pause start, and 5. Flashing for pulse start.
What is the maximum time delay this relay can provide?
The relay offers eight adjustable time ranges, with the maximum being up to 10 hours (36000 seconds).
Can this relay be powered by both AC and DC voltage?
Yes, it supports a rated control supply voltage Us at AC 50Hz from 24V to 230V, and at DC from 24V to 24V.
What type of output does the Metz Connect 110657 have?
It features one change-over contact output (SPDT).
How is the time delay adjusted on this relay?
The time is adjusted using a linear potentiometer on a relative scale, in conjunction with the selected time range via coding switches.
What are typical applications for this timer relay?
Common applications include staircase lighting control, surge protection control, signaling, and general automation tasks requiring timed switching.
What is the physical size of the relay?
The relay has a compact width of 22.5mm, a height of 60mm, and a depth of approximately 61.3mm, designed for DIN rail mounting.
Troubleshooting
Relay does not activate when input signal is applied.
Verify that the control supply voltage is correctly connected and within the specified range. Check that the correct function is selected via the coding switches and that the time setting is appropriate.
Output remains energized or de-energized permanently.
Confirm the selected function mode is appropriate for the application. Ensure the time delay is not set to its maximum or minimum if it's causing unexpected behavior. Check the wiring of the output terminals.
Inconsistent timing performance.
Ensure the operating temperature is within the specified range (-10°C to 55°C). Check for voltage fluctuations in the control supply. Make sure the potentiometer is clean and free from debris.
Relay fails to switch after multiple cycles.
Inspect the output load connected to the relay; ensure it does not exceed the contact rating. Check for any mechanical obstruction if visible, though internal mechanisms are not user-serviceable.
Pros and Cons
Pros
- Highly versatile with multiple programmable functions and time ranges.
- Easy to configure with coding switches and a linear potentiometer.
- Compact 22.5mm width saves space in control panels.
- Compatible with a wide range of AC and DC control voltages.
- Reliable 1 change-over contact output.
Cons
- Screw terminals require careful wiring, especially in tight spaces.
- Linear potentiometer scale is relative, requiring initial calibration for precise absolute timing.
- No advanced digital interface for remote configuration or monitoring.
- Operating temperature range is limited to -10 to 55°C.
Setup, Compatibility & Care
Setup:
- Mount the relay onto a standard 35mm DIN rail.
- Wire the control supply voltage (Us) to the appropriate terminals (terminals 1 and 2 for AC/DC).
- Connect the input signal (e.g., button for staircase lighting) to terminal 14.
- Connect the output load to the change-over contact terminals (15, 16, 18).
- Use the coding switches to select the desired function (e.g., on-delay, off-delay).
- Adjust the time range using the potentiometer dial.
Compatibility:
- Control Supply Voltage: AC 24-230V (50Hz) and DC 24V.
- Output Contact: 1 change-over contact, rated for 250V AC.
- Mounting: Compatible with standard 35mm DIN rails.
- Environmental: Suitable for indoor use within an operating temperature range of -10°C to 55°C.
Care:
- Ensure power is disconnected before cleaning or maintenance.
- Wipe the exterior with a dry or slightly damp, lint-free cloth. Avoid using solvents or abrasive cleaners.
- Periodically check wiring connections for tightness and signs of corrosion.
- Ensure ventilation around the unit is not obstructed.
