2 Relay Module MDA2Y, efficient control and action.
Cofem’s MDA2Y Module is a microprocessed, addressable device designed to be easily integrated into the detection system loop. This module allows to control and manage two relays in a precise and efficient way, increasing the system’s response capacity to various situations. With short-circuit isolator, it ensures the continuity of communication and reliability of the system at all times, becoming an essential tool to improve the operability and flexibility of the installation.
Key features
The modules are powered by the loop connection, but require a 30V auxiliary power supply to provide the necessary power to the devices governed by the relays. These monitor the presence of voltage on the 30V auxiliary supply line as well as on the outputs of the monitored relays.
The module is protected by a 0.9 A self-rearming fuse and each supervised output is protected by a 0.5 A fuse.
The blinking of the transparent red LED indicates communication with the control panel. The green LED lights up to indicate the tripping of one or both relays.
It is a module with two independently operated relay outputs (two functions), both in its type of application (siren, maneuvers or crossed relay), as well as in its timing and combination of sensors that activate them.
In idle state the MDA2Y monitors each output by means of a 33 kO resistor, indicating open line or crossed line status.
It is supplied in rectangular modules made of heat-resistant ABS.
The MDA2Y module is certified according to EN 54-18 by AENOR, and CE marked according to the European Construction Products Regulation (EU) No. 305/2011.
