The relay interface modules produced
by EL.CO. fall in to two categories:
STATIC RELAY INTERFACE MODULES:
Using the relays in the solid state in the interface offers yhe
following advantages:
- low absorption
- hight switching frequency
- long mechanical-electrical operating life
- no recoil and no oxidation of contacts
- no electrics arcs
ELECTROMECHANICAL RELAY INTERFACE MODULES:
Using the electomechanical relay in the interfaces offers the following
advantages:
- possibility of switching higher currents than those of the solid
state relays
- low cost
CE reference standards:
EN60947-5-1 / CEI 17-45 / IEC 947-5-1
