The Dold IK8800.11DC12V is an industrial remote switch designed for use in electrical control and switching systems. The device operates in impulse mode and is powered by a 12 V DC voltage. It features a contact configuration with one changeover contact and is designed for mounting on a DIN rail system. The width is 17.5 mm, enabling compact installation in enclosures. The switching position is indicated by a visual indicator, and an integrated button allows manual actuation of the contacts. The devices comply with IEC/EN 60669 standards and are suitable for applications requiring low energy consumption and reduced wiring effort.

Applications
The IK8800.11DC12V is typically used in systems where multiple room switches or remote switches are connected to a central switching point. The impulse control enables the contacts to be actuated with each current pulse, remaining in the respective position until the next pulse occurs. This is particularly advantageous in systems with multiple switches, as it reduces wiring complexity. The devices can be mounted closely together in impulse operation, whereas for continuous switching, a mounting distance of 7 mm between relays is required.

Functions and Equipment in Detail
The device features a changeover contact as output contact, with a maximum contact configuration of up to four changeover contacts. The contacts are actuated with each current pulse and remain in the respective switching position until the next pulse occurs. An integrated button enables manual actuation of the contacts, which is useful for maintenance or testing purposes. The switching position is indicated by a visual indicator, which visually shows the state of the contacts. The operating voltage is 12 V DC, and the thermal current Ith is 16 A, indicating the maximum permissible current load.

Technology Explained Simply
The impulse operation means the device does not continuously consume power, but only when a button or control is activated. This results in low energy consumption and reduced heat generation within the device. The contacts switch with each pulse and remain in the new position until the next pulse arrives. The switching position is indicated by a visual indicator, which lights up red when the contacts are activated. The width of 17.5 mm allows compact mounting on a DIN rail system, minimizing space requirements in the enclosure.

Compatibility and Accessories
The device is designed for mounting on a DIN rail system and complies with IEC/EN 60669 standards. It can be used in combination with other remote switches from the IK 8800 series, with mounting distances varying depending on the operating mode (impulse or continuous operation). The contact configuration is configurable up to four changeover contacts, with the variant described here featuring one changeover contact. The devices are designed for industrial environments, with an operating temperature range between -20 °C and +45 °C.

Mounting and Installation
Mounting is performed on a DIN rail system, with the width of 17.5 mm enabling compact installation. In impulse operation, the devices can be mounted closely together, while for continuous switching, a spacing of 7 mm between relays must be maintained. The connection terminals are designed for connecting control and load lines, with the terminal designations (A1, A2, 13/14, etc.) detailed in the manufacturer’s datasheet.

Advantages in Operation
The impulse operation results in low energy consumption and reduced heat generation in the device. The integrated switching position indicator allows for quick visual inspection of the operating status. The manual actuation button provides additional flexibility during maintenance. The compact width of 17.5 mm and DIN rail mounting simplify installation in enclosures. Compliance with IEC/EN 60669 standards ensures reliability and safety in industrial applications. The maximum contact configuration of up to four changeover contacts offers flexibility in configuring switching systems.
