1 Relay Module MDA1Y, compact and efficient control.
Cofem’s MDA1Y Module is a microprocessed, addressable device that is easily integrated into the detection system loop. This module allows a relay to be controlled accurately and reliably, expanding the functionality of the system by providing an immediate response to various situations. With a short-circuit isolator, it ensures communication stability and continuity of system operation, providing a simple and efficient solution for external device control.
Key features
The module is powered by the loop connection, but requires a 30V auxiliary power supply to provide the necessary power to the devices governed by the relays. It monitors the presence of voltage on the 30V auxiliary power 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 simultaneously operated relay outputs (with a single function), both in its type of application (siren, maneuver or pre-alarm), as well as in its timing and combination of sensors that activate them.
Relay output R1 is supervised by means of a 33 kO line terminating resistor, indicating open or crossed line status. Relay output R2 acts as an unsupervised NO and NC contact, its typical application being the tripping of fire door electromagnets. Considering the consumption produced on the system, it is recommended to install external power supplies (FAE) for more than 10 electromagnets in total per plant.
It is supplied in rectangular modules made of heat-resistant ABS.
The MDA1Y module is certified according to EN 54-18 by AENOR, and CE marked according to the European Construction Products Regulation (EU) No. 305/2011.
