This module has a relay with external 30V power supply and a technical signal input to discern the open or closed state of a dry contact. The module is protected by a 0.9A self-rearming fuse and the relay output is protected by 0.5A.<\/span><\/p>\n

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 relay marked “R1”. The relay is programmed with a single function (siren, maneuvers or crossed relay) as well as in its timing and combination of sensors that activate them. Likewise, the presence of voltage on the 30V auxiliary power supply line and also on the relay output is monitored. The voltage supplied by the relay output is 30V.<\/span><\/p>\n

The technical signal input has a 10k\u03a9 resistor connected in series with the dry contact. The contact must be open in the idle state and closed in the event of a fault. At the input (marked as IN2) it detects the closed contact with ALARM category.<\/span><\/p>\n

There is also the MYOAF version, whose operation is identical to the MYOA, except that the closed contact is detected as a FAULT.<\/span><\/p>\n

The MYOA monitors each external line (relay output and technical signal input) with a 33k\u03a9 resistor on each, indicating open line or crossed line status.<\/span><\/p>\n

The blinking of the transparent red LED indicates communication with the control panel. The permanent lighting of the red LED indicates the alarm status at its input, while the lighting of the green LED indicates the tripping of the relay.<\/span><\/p>\n

The device is supplied in a rectangular, heat-resistant ABS box, to be mounted on surface or on DIN rail.
<\/span><\/p>\n

The module is certified according to EN 54-18 Standard, and CE mark according to the European Regulation of Construction Products (UE) N\u00b0 2024\/3110.<\/span><\/p>\n
