Analog daily timer PLUG&PLAY T31 Su/Wi, quartz drive 412823

Analog daily timer with quartz drive for automatic control of electrical installations

The MicroRex T31 Su/Wi analog timer is a compact Plug&Play solution that enables automatic switching on and off of electrical circuits according to a programmed daily schedule. The device is ideal for controlling lighting, heating, and other loads requiring precise time control.

Construction and technical parameters of the device

The timer is mounted on a DIN rail, occupying 3 modules. The quartz drive ensures accuracy of ±0.2 seconds per day and a battery backup of 6 years, eliminating the need for frequent calibrations.

The device is equipped with one switching channel with a potential-free contact with a capacity of 16A at 250V AC. Programming is done in 15-minute steps, with the shortest possible switching time being 30 minutes. The control dial allows for intuitive setting by adjusting segments corresponding to the desired operating hours.

Functionality and automation

The timer offers full automatic daily control functionality. Upon power restoration, there is an automatic setting of the current time, and the device automatically switches between daylight saving/standard time without user intervention. Additionally, manual override and an advance switch setting function are available, allowing for a temporary change in operating mode.

Power supply is 230V AC at a frequency of 50-60Hz, and the device operates in temperatures from -10°C to +55°C. The IP20 protection rating guarantees safe operation in switchboards.

Normative compliance and operating conditions

The device meets IEC/EN and VDE standards, confirming its safety for use in electrical installations. Connections are made with conductors having a cross-section from one and a half to four square millimeters, and the housing color (RAL) facilitates equipment identification in the electrical switchboard.

Storage temperature ranges from minus ten to plus sixty degrees Celsius.
