The Tyco MTL5561 517.001.302 is a loop-powered 2-channel galvanic isolator for use with conventional fire and smoke detectors in hazardous areas. The triggering of a detector causes a corresponding change in the safe-area current. The unit features reverse input polarity protection, while “no-fail” earth fault detection on either line can be provided by connecting an earth leakage detector to terminal 3 and/or 6. The Tyco 517.001.302 Galvanic Isolator is CE marked and replaces the MTL3043 barrier option. The MTL5561 is suitable for connecting loads in Zone 0, IIC, T4-T6 hazardous areas if suitably certified.
