Industrial Timer Relay MTN 94R-3020 — MTN 94R-3020, DIN‑rail control relay with timing functions

The MTN 94R-3020 is a DIN-rail timer relay designed for control cabinets and industrial automation panels. It provides a range of programmable timing functions for delayed ON/OFF switching, pulse generation and interval control. Built for use in electrical control circuits, this timer relay supports sequential machine operations, motor start delays, lighting control and general process timing where repeatable, reliable time-based switching is required.

Advantages

The device offers multiple timing modes in a compact DIN-rail housing suitable for standard control cabinets. It simplifies wiring and reduces the need for separate timing modules by combining several timing functions in a single relay. The relay is intended for straightforward installation and adjustment, allowing technicians to set delay and pulse parameters on site. Its construction is focused on consistent switching behavior and integration with other control components.

Suitable for

• Motor start delay and protection circuits
• Lighting and HVAC timing control
• Sequential machine and conveyor operations
• Process timing in industrial and building automation

Key specifications

• Mounting: DIN-rail compatible for control panel installation
• Function: Programmable timing functions including delayed ON/OFF, pulse and interval control
• Form factor: Compact relay module designed for electrical cabinets
• Control: Adjustable timing parameters for field settings
• Output: Relay contacts for switching control circuits

How to use

Mount the MTN 94R-3020 on a standard DIN-rail inside the control cabinet and connect the supply and load wiring according to the system schematic. Select the required timing function and adjust the time range and setpoint using the unit's controls. Verify correct wiring and perform functional tests by applying supply voltage and observing the timed switching behavior before placing the relay into normal operation. Follow the equipment manufacturer's electrical safety practices during installation and testing.

Usage recommendations

Use the timer relay within the rated supply voltage and ambient conditions, and incorporate appropriate protection such as fuses or circuit breakers. For repeatable results, allow for a commissioning period to fine-tune time settings and confirm compatibility with connected loads and contactor coils.
