3.2.MECHANICAL DESCRIPTION
The model number and electrical characteristics of the unit are indicated on the label located on the right side of the relay case.
The metallic case of the unit is highly resistant to corrosion. It is made of stainless steel (AISI 304), coated with an epoxy layer, and the rest of the metallic pieces are covered with a high quality resistive coating that has successfully passed at least 96 hours in the salt spray chamber (S/N ASTM
The front of the relay is made of a conductor thermoplastic, flame retardant (V0), highly resistive material, which guarantees the unit’s immunity to all kinds of EMI/RFI/ESD interferences. As well, an IP51 (IEC 529) protection degree against dust and water through the front and with the relay mounted in the panel.
In order to guarantee safety and preventing access to the unit by unauthorized personnel, the front communications port and the operation mode key are protected by a sealable cover.
