EL.MO. MD4IO — 4 input and 4 output FYRA line module

MD4IO is a 4-input, 4-output module for FYRA addressable analog loops.

• •Specifically, it features 4 balanced/unbalanced inputs for alarm and fault signaling (line open and line short), used to connect 4 sensors or other conventional devices to the detection loop equipped with NO output relay contacts and 4 C-NO-NC bistable relay outputs, rated 2 A at 30 Vdc, which support the connection of only those devices required by current regulations in the case of unsupervised outputs (e.g. devices for technological events).
• •The module integrates an on-board line isolator and 8 two-color LEDs (4 for inputs and 4 for outputs) that provide information about the status of inputs/outputs and communication.
• •The small plastic container is also suitable for installation in flush-mounted boxes.
• •The MD4IO module is certified CPR 305/2011 EN 54-17 and EN 54-18
