MTL5522 SOLENOID ALARM DRIVER MTL5522
Overview
The MTL5522 is a loop-powered module which enables a device located in the hazardous area to be controlled from the safe area. The MTL5522 can drive a certified intrinsically safe low-power load, as well
as non-energy-storing simple apparatus such as an LED. The unit's input/output isolation allows the control switch to be connected into either side of the 24V dc supply circuit.

Safety description
Uo=25V Io=166mA Po=1.04W Um = 253V rms or dc
SIL capable
These models have been assessed for use
in
IEC 61508 functional safety applications.
SIL3 capable for a single device (HFT=0)
when the required function is to deenergise
the output.
SIL1 capable for a single device (HFT=0)
when the required function is to energise
the output.
See data on MTL web site and refer to the
safety manual.
