Modular analog timer ETI APC-DR1 230V single-pole 16A for DIN-rail circuits

The Modular analog timer ETI APC-DR1 230V single-pole 16A is a DIN-rail mounted mechanical time switch designed to control single-pole circuits up to 16 A. The device uses an analog dial with interchangeable pins for setting daily on/off times, providing simple programmable control for lighting, heating elements, or other single-phase loads in residential and light-commercial electrical distribution panels. Its modular form factor fits standard DIN rails and integrates with common consumer units and distribution boards.

Advantages

The mechanical design offers straightforward, reliable operation without the need for software or digital configuration. The analog dial with pins allows easy visual confirmation of programmed switching intervals and quick manual adjustments. With a rated switching capacity of 16 A at 230 V and single-pole contact arrangement, the timer is suitable for typical lighting circuits and small resistive loads. The DIN-rail mounting and compact modular width support space-efficient installation inside electrical panels.

Suitable for

• Timed control of indoor and outdoor lighting circuits (single-pole)
• Scheduling simple heating loads such as convectors or towel rails with resistive elements
• Automation of pumps or fans with compatible single-phase loads
• Integration into residential or small commercial distribution boards on standard DIN rails

When it may not be suitable

This analog timer is not intended for direct control of three-phase loads or for switching currents above 16 A. It lacks advanced digital features such as multiple weekly programs, astronomical functions, or remote network control, so it may be unsuitable where precise multi-week scheduling, daylight-based switching, or remote management is required.

Key specifications

• Supply voltage: 230 V AC
• Contact configuration: single-pole (1P)
• Rated switching current: 16 A
• Control type: mechanical analog dial with removable pins for on/off intervals
• Mounting: DIN-rail (standard rail profile)
• Typical applications: lighting and resistive loads in distribution panels

How to use

Install the timer on a standard DIN rail inside the distribution board and connect the load and supply according to the wiring diagram printed on the device. Set the current time on the analog dial, then insert or remove the pins to define on/off periods across the 24-hour scale. After programming, restore power and test the timer by advancing the dial or waiting for scheduled switching events. Manual override, if present, can be used to force the output on or off for testing or temporary control.

What to consider before purchase

• Confirm the load type is single-pole and the current does not exceed 16 A
• Ensure there is available DIN-rail space in the distribution board for a modular device
• Decide if analog programming meets your scheduling needs or if digital/astronomical features are required

Usage recommendations

Use the ETI APC-DR1 for straightforward daily schedules where simple, reliable mechanical timing is preferred. For lighting circuits, verify inrush currents and derating for inductive loads; for resistive heaters and pumps, confirm steady-state current remains within the 16 A rating. Where multiple programs or remote control are needed, consider a digital timer alternative.
