MTL5532 MTL ISOLATOR POWER SUPPLY

Location of fieldbus device(s)
Zone 0, IIC, T4–6 hazardous area if suitably certified
Hazardous-area fieldbus power supply
18.4V ± 2%
105Ω ±3% dc impedance
80mA maximum current
Maximum cable length
Determined by IS requirements, depending on other devices
attached and maximum acceptable voltage drop along cable
Digital signal transmission
Compatible with 31.25kbit/s fieldbus systems and complies
with fieldbus standards†
Supply voltage
20 to 35Vdc
LED indicator
Green: one provided for power indication
Power requirement, Vs, with 80mA output load
135mA typical at 24V
105mA at 35V
Power dissipation within unit, with 80mA output load
2.3W typical at 24V
2.6W maximum at 35V
Note: To allow adequate heat dissipation under all likely thermal
conditions, it is recommended that MTL5053’s are installed on a
horizontal DIN-rail mounted on a vertical surface* with a 10mm
space between adjacent units. MTL MS010 10mm DIN-rail module
spacers are available for this purpose.
* If an MTL5053 is mounted in a non-optimum orientation, the
maximum operating temperature is reduced to 45°C.
Isolation
250V ac between safe- and hazardous-area circuits and power
supply
