RELAY INTERFACE MODULES

Product catalog summary

Overview of Relay Interface Modules
The document provides a comprehensive overview of relay interface modules by EL.CO. S.r.l., categorized into static and electromechanical types, each with unique advantages for various applications.

Static Relay Interface Modules
These modules use solid-state relays, offering benefits such as low power consumption, high switching frequency, long life, no contact bounce or oxidation, and no electrical arcs.

Electromechanical Relay Interface Modules
These modules can switch higher currents than solid-state relays and are cost-effective.

Standards and Compliance
The modules comply with CE standards EN60947-5-1, CEI 17-45, and IEC 947-5-1.

Product Series and Specifications

RM Series: Modules with one exchange contact, available with terminal input or flat connector, with options for spring base and fuse carrier.
SM Series: Slim electromechanical relays with one exchange contact.
RB Series: Details not specified.

Technical Data

Output: Max nominal current of 10A, voltage up to 250Vac/125Vdc, mechanical life of 1x10⁶ cycles.
Input: 12Vdc and 24Vdc options, input currents of 54mA and 22mA respectively.
Operating Temperature: -20°C to +55°C.

Wiring Diagrams and Dimensions
Includes wiring diagrams for various relay configurations and specifies dimensions for each module type.

Accessories
Includes sockets for printed boards and springs, with options for cables.

Specifications and Model Modifications
Models can be modified to include a fuse carrier ('F'), a base with spring ('Z'), or both ('FZ').

Modular Interface Selection
Details on modular interfaces with static relays, specifying models without base and fuse carrier, highlighting models like SSR21-3240B and SSR20-524B.

Relay Interface Modules
Details on relay interface modules, including dimensions and wiring diagrams, available in configurations of 1, 4, 8, and 16 relays.

Accessories and Additional Features
Includes sockets for printed boards, springs, and options for DIN bar attachment. Custom outputs with fuse protection available upon request.

Series and Relay Types
Information on series like ECLR with electromechanical relays and EZD-ECLR with solid-state relays, including input voltage, output current, and connection types.
