6.3.3 MTL5533 - Vibration Transducer Interface
(Reference use only: Terminated product, use 2 x MTL5531)
Two channel
The MTL5533 repeats signals from vibration sensors in a hazardous area, providing outputs
for monitoring systems in the safe area. The interface is compatible with 3-wire eddy-current
probes and accelerometers or 2-wire current sensors, and selection of the mode for each
channel is made with the switches on the side of the module.

* Note: When using 2-wire sensors, ensure
that terminals 1 & 2 and 4 & 5 have wiring
links as shown in the wiring diagram above.
WARNING!
To enable adequate heat dissipation from the MTL5533 modules, they
must be installed on the DIN rail with a 10mm space between adjacent
units. Eaton produce the MS010 DIN rail module spacer for this purpose
(packs of 5 - see Section 4.3), and these then enable operation in ambient
temperatures of up to 50°C in vertical or horizontal orientation.
