The ECE 602-0 input controller extension from Siedle is a module for expanding the base controller EC 602- and serves to integrate additional switching outputs into intercom systems. The device is delivered in a control panel housing and enables the expansion of the controller by six additional potential-free switches. These outputs can be used to control various functions in a building entrance system, such as door openers, light switches, or alarm systems. The extension is specifically designed for systems operating via the Siedle Vario-Bus, where input devices such as code lock modules COM 6- or electronic key reader modules ELM 6- capture access data and transmit it to the controller.

Applications

The ECE 602-0 is intended for use in professional low-voltage installations in the field of building automation. It is used in conjunction with the input controller EC 602- to extend its functional range. The six additional switching outputs enable the control of up to eight functions when combined with a COM 6- or ELM 6- module. This is particularly useful in multi-family houses, office buildings, or other facilities with complex access control systems, where multiple doors or functions are to be controlled via a central system.

Functions and Equipment in Detail

The module provides six potential-free switches serving as switching outputs. These are designed for controlling external devices, with the load limit of the system determined by the specifications of the main controller (EC 602-). The extension is delivered in a standard control panel housing with dimensions 53.5 mm (width) × 89 mm (height) × 60 mm (depth), corresponding to the size of a 3-grid module. Mounting in a control panel is done in the usual manner within an electrical distribution box or control panel.

Technology Explained Simply

The ECE 602-0 is powered via the main controller EC 602-. The operating voltage is 24 V, with the maximum current draw of the entire system (EC 602- and ECE 602- combined) not exceeding 400 mA. Power supply is provided via the contacts of the EC 602-, eliminating the need for a separate power supply for the extension. The protection rating IP20 indicates that the device is protected against contact with fingers and against solid foreign objects, but not against water or dust. It is therefore intended for indoor use only, not for outdoor applications.

Compatibility and Accessories

The extension is specifically designed for use with the input controller EC 602-. It is used in systems operating via the Siedle Vario-Bus, where input devices such as the code lock module COM 6- or the electronic key reader module ELM 6- capture access data. The combination with these modules enables the control of up to eight functions. The extension is not intended for other controller models or systems that do not operate on the Siedle Vario-Bus.

Installation and Mounting

Mounting is carried out in a standard control panel housing. The module is inserted into the designated 3-grid position and connected to the corresponding wiring of the EC 602-. Power supply is provided via the main controller, eliminating the need for additional power cables. Installation must be performed by qualified specialists in accordance with applicable standards and regulations for low-voltage installations.

Operational Advantages

The ECE 602-0 enables flexible expansion of the functionality of Siedle intercom systems without replacing the main controller. The six additional switching outputs allow multiple functions to be controlled via a central system, reducing system complexity and simplifying maintenance. Integration into existing systems requires no additional power supply, simplifying installation and reducing the number of required cables. The operating voltage of 24 V and the current limit of 400 mA ensure safe and reliable operation.
