MTL5061 FIRE/SMOKE DETECTOR INTERFACE two-channel With Good Price In Ready Ship

MTL5061 FIRE/SMOKE

DETECTOR INTERFACE two-channel, loop-powered

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 corresponding 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 OF MTL5061

See also common 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

whichever is the lower of:

Vin – (0.38 x current in mA) – 2V or

21V – (0.35 x current in mA)

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

6 to 35V dc

Quiescent safe-area current at 20°C

(hazardous-area terminals open-circuit)

<400µA/ channel, Vin = 24V dc

Maximum power dissipation within unit

0.7W at 24V with 40mA signal (each channel)

1.2W at 35V with 40mA signal (each channel)

Safety description
