MTL Intrinsic Safety MTL4533 MTL 4500Range Isolator

MTL Intrinsic Safety MTL4533 MTL 4500Range Isolator

Detailed Product Description
Improving upon the widely adopted, enormously successful, "industry standard" MTL4000 Series was a big challenge but the innovative MTL4500 Series includes several new features for backplane mounting isolating interfaces. This new family easily integrates with the I/O equipment of all major instrumentation and DCS suppliers in the same secure manner as its predecessor.

Installation
a) The installation must comply with the appropriate European, national and local regulations, which may include reference to the IEC code of practice IEC 60079-14. In addition, particular industries or end users may have specific requirements relating to the safety of their installations and these requirements should also be met. For the majority of installations the Directive 1999/92/EC [the ATEX Directive - safety of installations] is also applicable.
b) This apparatus is an associated electrical apparatus and is normally mounted in a non-hazardous [safe] area. Specific apparatus described as Category 3 compliant may be installed in a Zone 2 location providing that the relevant installation conditions are met. When mounted in a Zone 2 location the apparatus must be provided with an enclosure, which offers an additional degree of protection appropriate to the area classification.
c) Unless already protected by design, this equipment must be protected by a suitable enclosure against:
i) mechanical and thermal stresses in excess of those noted in the certification documentation and the product  specification
ii) aggressive substances, excessive dust, moisture and other contaminants.Read also the Special Conditions for Safe Use (below) for any additional or more specific information.
Special Conditions of Safe Use for Zone 2 applications
a) When used in Zone 2, the equipment must be installed in an enclosureor an environment that provides a degree of protection of at least IP54
and meets the relevant material and environmental requirements of EN 60079-0:2012 and EN 60079-15:2010.
b) The equipment must not be inserted or removed unless either:
i) the area in which the equipment is installed is known to be nonhazardous or
ii) the circuit to which it is connected has been de-energised.
c) The 24V supply for this equipment must be derived from a regulated power supply complying with the requirements of European Community Directives.
d) For 4511, 4514, 4514B, 4514D, 4516, 4516C, 4517, 4526 & 4532 only:Relay contacts may switch up to 35V, 0.5A and 10W.For 4575: Relay contacts may switch up to 35V, 250mA.
e) Any backplane used does not form part of this certificate and shall be separately certified for use in Zone 2.
f) The associated backplane must be fitted with MTL4500 retention clips (use type MCK45 if not fitted) that allow the equipment to be ‘clipped’
to the backplane. The retention clips shall always be in place when theequipment is energised.
g) For 4573 Maximum Input/Output parameters – see certificate
