VBA-4A-70MM

AS-Interface stack light module

Описание

The signal column module VBA-4A-70MM is an AS-Interface module with 4 virtually wearproof semiconductor relay outputs which can trigger up to 4 stages of a signal column. AS-Interface module for stack lightfa. The connection of the external auxiliary voltage and the AS-Interface takes place via screw terminals in the corresponding connection element which is easily fitted to the module via a bayonet system. The supply of the connected outputs can take place either from the internal power supply of the module (from AS-Interface) or via an external power source. Switching takes place via a sliding switch inside the element. The selection of the external power supply is indicated via an LED (AUX). The outputs are protected against reversal, overload and short circuit. An LED to indicate the AS-Interface voltage is available, another indicates errors in the AS-Interface communication. For parameterization there is an addressing jack in the element protected against external interference.
