MDD-R4/T Modular relay device
MDD-L32/T digital visualization and control units are designed for status visualization of up to 32 detectors, and for control of other devices (e.g. signalling) through contact outputs (4 pieces) and 12VDC alarm outputs (2 pieces) in Digital Gas Detection System.
Communication with MDD-265/T supervising unit is carried out in industrial standard RS-485 under MODBUS RTU protocol.
