The Dold time relay AA7610.22/034 is a delayed-on time relay of the MINTIMER series, designed for use in industrial control systems. It enables time-delayed switching of devices and components, for example, to account for motor start-up behavior or for sequential activation of system parts. The device operates with a rated voltage of AC 230 V and a rated frequency of 50/60 Hz. The time delay is continuously adjustable via a rotary switch and covers the range from 30 seconds to 6 minutes. The time function is configured as delayed-on, meaning that the contacts switch only after the set delay time has elapsed, once the input voltage is applied.

Applications
This time relay is suitable for applications requiring controlled temporal sequencing of switching operations. Typical use cases include controlling pumps, fans, lighting systems, or other electrical loads where immediate switching is not desired or technically impractical. Use in enclosures is provided for by the housing type enclosure and a width of 45 mm, enabling integration into standard control panels.

Functions and Equipment in Detail
The device features contact configuration with 1 normally open contact, 1 delayed normally open contact, and 1 delayed normally closed contact, where the delayed contacts implement the delayed-on function. The output contacts are rated for an operating voltage of AC 250 V. The repeatability accuracy is ≤ ± 0.5 % of the scale end value, with a permissible deviation of ≤ ± 1 % within the range up to 6 seconds. The time progression is indicated by a red pointer on the device scale, visually displaying the progress of the set delay time. The switching position is indicated by viewing symbols showing the state of the contacts.

Technology Explained Simply
The time control is based on a purely mechanical timing mechanism, controlled by a continuously adjustable rotary switch. Adjustment is made via a black setting pointer on an absolute scale, allowing precise and wide-range setting of the delay time. The contact response time is less than 35 ms, and the reset time is less than 60 ms. The re-arming time is < 150 ms, which is very short, ensuring the device is quickly ready for operation again after switching off. The contact materials consist of AgNi with a gold layer of 0.2 μm, ensuring high switching capacity and long service life.

Compatibility and Accessories
The time relay is designed for operation in industrial control systems and complies with the standard EN 61812-1. It is designed for continuous operation and can be used at operating temperatures from -20 °C to +55 °C. The permissible operating altitude is up to 2000 m above sea level. The electrical service life is at least 100,000 switching operations at 3 A and AC 230 V, and 500,000 switching operations at 1 A. The mechanical service life exceeds 30 million switching operations or over 15,000 operating hours. Short-circuit resistance is ensured with a maximum fuse rating of 10 A gG/gL.

Mounting and Installation
Mounting is carried out in enclosures or control panels. The width of 45 mm allows compact placement in standard control cabinets. The terminal connections are designed for wiring, with the exact terminal assignment to be found in the function diagram in the datasheet. The delay time is adjusted via the rotary switch on the front of the device.

Operational Advantages
The continuous adjustability of the delay time over a wide range offers flexibility in adapting to different applications. The high repeatability accuracy and short re-arming time ensure reliable and precise switching operations. The mechanical design without electronic components increases the robustness and service life of the device. The visual indication of time progression and switching position facilitates commissioning and maintenance.
