DIN rail electronic timer switch QOLTEC 50983, battery powered, for automation circuits

Electronic DIN-rail timer switch QOLTEC 50983 is a battery-powered device designed for time-controlled switching in electrical and automation circuits. It mounts on standard DIN rails and provides programmable timing functions for lighting, pumps, motors and other loads where scheduled control is needed. Battery operation ensures retention of settings without external power and allows the timer to maintain schedule memory during power outages.

Advantages

The QOLTEC DIN-rail timer offers compact installation on standard rails and a self-contained power source that preserves configuration. Its programmable timing functionality enables repeatable daily or weekly schedules for load switching. The device is suitable for integration into control panels and automation systems where space is limited and reliable timekeeping is required. Easy-to-access controls and clear indication of operating state simplify setup and maintenance.

Suitable for

• Scheduled control of lighting in residential, commercial or industrial panels
• Automated switching of pumps and small motors
• Time-based control for HVAC zones, signage and irrigation circuits
• Integration into automation circuits and control cabinets

Key specifications

• DIN-rail mounting compatible with standard rails
• Battery-powered design for memory retention during power loss
• Programmable timing functions with daily and weekly schedule options
• Suitable for switching lighting, pumps, motors and similar loads
• Compact enclosure for installation inside control cabinets

How to use

Install the timer on a standard DIN rail inside the distribution or control cabinet and connect input and output conductors according to the circuit diagram. Program the required on/off times and schedule pattern using the device controls, then verify operation by observing the switching of the connected load at the set times. The battery maintains the programmed settings when external power is removed; replace the battery according to the manufacturer's guidance to ensure continuous memory retention.

Recommendations

For reliable operation, mount the timer in a dry, ventilated enclosure protected from excessive vibration and temperatures outside the specified operating range. Verify load ratings and switching capacities before connection, and use the device within its intended application scope. Regularly check battery condition and backup power settings to avoid loss of schedule data.
