MTL5561 DIN Rail Isolating IS Interface Unit Two, fully floating, loop powered

MTL5561 DIN Rail Isolating IS Interface Unit

   The MTL5561 is a loop-powered 2–channel interface for use with conventional fire and smoke detectors located in hazardous areas.

• Product type : Fire And Smoke Detector Interface

• 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 300?

• Transfer accuracy at 20°C : Better than 400µA
