Description
The MTL5061 is a loop-powered two-channel interface for use with conventional fire and smoke detectors located in hazardous areas. In operation, the triggering of a detector causes a orresponding change in the safe-area circuit. The unit has reverse input polarity protection, while ‘non-fail’ earth fault detection on either line can be provided by connecting an earth leakage detector to terminals 3 or 6.

Specification
Number of channels
Two
Location of detectors
Zone 0, IIC, T4–6 hazardous area if suitably certified
Div. 1, Group A hazardous location
Current range
1 to 40mA, nominal
Integral input polarity protection
Input circuit protected against reverse polarity
‘No-fail‘ earth fault protection (optional)
Enabled by connecting terminals 3 and 6 to the MTL4220 earth
leakage detector. If a fault on either line of each channel is
proclaimed: unit continues working.
Note:1. The earth leakage detector introduces a 100µA, 1Hz ripple to the
field circuit.
Minimum output voltage Vout at 20ºC

Response time to step input
Settles to within 500µA of final value within 30ms
Hazardous-area output
Maximum output voltage 28V from 300Ω
Transfer accuracy at 20°C
Better than 400µA
Temperature drift
<10µA/°C (–20 to 60°C)
Loop supply voltage
