Relay module SLS-20 for selective impedance measurement of 8 loudspeaker circuits.
The control and analysis is done by the monitoring and logging system SLS-1000.
An activation of the relay is displayed by LED.
The installation connections are realized by pluggable screw technic.
The module is designed to be assembled on a 35 mm guide.

Control signal input module with 16 inputs isolated by opto-couplers.
The accessed inputs are visually indicated by an LED.
The Functions of the individual inputs can be programmed by software.

 

8-channel relay module for selectively connecting 8 loudspeaker zones or for outputting so-called digital control signals.
Operation of the relays is indicated by means of LEDs.
The contakt functions are hardware-programmable for different applications.
The 8 relays may be split into 2 groups of 4.

8-channel relay module for controlling circuits selectively.
Each relay is provided with a floating contact which may be configured as a normally closed or a normally open contact.
Operation of the relays is indicated by means of LEDs.

The conductors of 4 independents control keys can be monitored by the CM-24-/4.
The module recognises short-circuit and interruption, as well as ground fault of one or another conductor.
A selective indication of the breakdown criteria via LED eases the error localisation.
The release of the events (alarm tone, test, etc.) occurs over potential free opening or closing contacts. A common error contact displays the duly state of the lines.
