MTL5561 product description:


The MTLx561 is a loop-powered 2–channel interface for use with conventional fire and smoke detectors located in hazardous areas. In operation, the triggering of a detector causes a corresponding change in the safe–area current. The unit features reverse input polarity protection.


Number of channels Two, fully floating, loop powered Location of fire and smoke detectors Zone 0, IIC, T4–6 hazardous area if suitably certified Div. 1, Group A, hazardous area Input voltage 6 to 30V dc Current range 1 to 40mA, nominal Quiescent safe–area current at 20°C (hazardous–area terminals open circuit) < 400µA at Vin = 24V per channel Integral input polarity protection Input circuit protected against reverse polarity Minimum output voltage Vout at 20°C For Vin ≤ 25V: Vout = Vin – (0.38 x current in mA) – 2V For Vin > 25V: Vout = 22.5V – (0.35 x current in mA) Maximum output voltage 28V from 300Ω Transfer accuracy at 20°C Better than 400µA
