S Size Form C (Changeover) Reed Relay

• Compact footprint.
• Changeover contacts.
• PCB Mount.
• Available with or without magnetic screen.
• Up to 3W switching power.
• Up to 1.2A carry current.
• Small package size with compact footprint.
• Rhodium contacts for low contact resistance and high durability.
• Often used in applications which require circuit protection or circuit breakers.

The S3 series is a compact reed relay with changeover contacts which are often used for safety critical applications.

Low contact resistance, through the use of Rhodium contact reed switches, makes the S series suitable for many high voltage applications at DC and low frequency, where performance and reliability are paramount.

These are PCB mount relays, though custom options may be available on request.

UL Approved* Miniature SIL Reed Relay with Form B (N/C) Contacts

•  Single-in-line package
•  1.5kV Isolation Voltage across contacts
•  1.3A carry current
•  Up to 1000V switching voltage

The S1 Form B series is a miniature high voltage single-in-line reed relay for applications where space saving is a prime consideration, with normally closed contacts.

The coil pins are positioned near the centre of the relay while the contact pins are near the ends to give improved isolation between the high voltage contacts and the low voltage coil.

Whatever your application, the easyE4 control relay allows for control systems that are efficient, flexible and easy to implement. The new easyE4 range is significantly more compact than the previous easy500, easy700 and easy800 series.

Thanks to the flexible expansion with up to 11 modules to a maximum of 188 inputs/outputs, as well as the large voltage range, the easyE4 is ideally suited for industrial and building applications. For additional flexibility, the intuitive easySoft programming software comes with four programming languages as standard, including function block diagram (FBD) and structured text (ST). New helpful function blocks, such as the automatic e-mail notification, as well as the possibility of creating own function blocks facilitate the programming for each user.

Thanks to the integrated web server, both mobile devices or an HMI can be used for visualization purposes. If used in combination with other products from the Eaton portfolio, the easyE4 can also be integrated into IIoT (Industrial Internet of Things) system architectures via the integrated Ethernet interface. In combination with the interrupt function, the powerful processor enables faster processing and response times during operation.

• Maximum flexibility, with up to 11 local expansion modules per base unit
• The 188 available inputs/outputs within a single easyE4 system provide coverage for a broad range of applications
• A compact product with a large voltage range (DC, AC and UC)
• Base units with different voltage types can be combined as required by means of the available expansion modules, which makes handling the easyE4 devices extremely easy
• The integrated Ethernet interface allows for a broad range of communication options
• A user-friendly programming environment with 4 programming languages (ST, FBD, LD, EDP) to choose from
• Various display and visualization options, eg. on mobile devices are possible thanks to the integrated display, web server and Ethernet options
• The integrated micro SD card facilitates data logging and customized starter programs
• Display with 3 background colors (red, green, white) for visualization of different device statuses
• DCF77 radio signal analysis as well as Ethernet services ensure highly precise date and time indication
• The interrupt function enables fast event recognition and rapid response times
