RELAY INTERFACE MODULES
RELAY INTERFACE MODULES
This document is a comprehensive catalogue from EL.CO. S.r.l., detailing their range of relay interface modules, which are divided into static and electromechanical types. The company reserves the right to modify specifications without prior notice.
These modules utilize solid-state relays, offering benefits such as low power consumption, high switching frequency, extended mechanical and electrical lifespan, and the absence of contact bounce, oxidation, and electric arcs.
These modules employ electromechanical relays, which can switch higher currents than solid-state relays and are generally more cost-effective.
The modules adhere to CE standards EN60947-5-1, CEI 17-45, and IEC 947-5-1.
- RM Series: Features one or two exchange contacts, with options for flat connectors and test push buttons.
- SM Series: Designed for slim electromechanical relays.
- RB Series: Details not specified in the excerpt.
- RS Series: Solid-state relay modules available in configurations of 1, 4, 8, or 16 relays.
- Output current: Up to 10A
- Input voltage: 12VDC or 24VDC
- Operating temperature: -20°C to +55°C
- Dielectric strength: 4000 VAC (coil-contact), 1000 VAC (contact-contact)
- Material: Nylon, UL 94 V0 rated
The document includes wiring diagrams for various relay configurations and specifies dimensions for each module type.
Available accessories include sockets for printed boards and springs, with detailed references in the catalogue.
- Relay input signaling LED
