Signal Module 2041 for main and approach light signal

Signal Module 2041 for main and approach light signal

This signal module is a further development of 2040. The decisive difference is its capacity to be used for light signals for differently polarised terminals. While only signals with a mutual positive connection could be used as return conductors in 2041’s precursor 2040, this no longer plays a role, thanks to the alternating current technology in 2041. Both positive and negative poles of the power supply can be used as mutual return conductors. Another advantage can be found in the wiring for the approach signal due to the elimination of additional diodes for decoupling. The respective approach signal (with up to three signal aspects) is directly connected to the signal module 2041! The polarity of the mutual return conductor also plays no part here!
The purpose of the signal module is to control a light signal with up to 4 aspects, by which an approach signal attached to the same tower as the main signal is prototypically dimmed when a main signal of ‘stop’ is shown. Electronics controlled by a microprocessor ensure realistic panning of the signal aspects. Via an in-built relay contact, the traction current or other form of control current can be controlled potential-free. And for travel in the opposite direction at a red signal, an individual gate is available. Activation occurs via a short ground impulse at the desired input. Built-in LEDs are for supervision purposes and always show the current signal aspect.

	Relay Module 2011 Relay Module 2011 The relay module houses 2 independently usable two-state relays each with two switch contacts. Each circuit in a relay is capable of carrying up to 2A and is designed for a maximum switching current of 24V. The relay is triggered by a negative impulse (ground). The position of each relay is retained even once the voltage has been switched off. Place and position of installation are uncritical. In addition to direct current voltage between 12 and 18V, this relay module can be operated with 16V alternating current voltage. Available with casing as 2011 or, at a lower price, without casing as 2111.   30,70 EUR (19 % VAT incl. excl. Shipping costs)
