A smart new approach in the production process : celduc’s industrial solutions overview

Solid State Relays offer more possibilities in terms of Diagnostics, Protections and Communication than electromechanical relays. These products features are very important for Industry 4.0. The purpose of industry 4.0 is to optimize manufacturing operations quickly and efficiently by providing information such as performance and other issues that may need attention.

In this new blog article we present the celduc’s solutions in order to explain how celduc, as a French manufacturer of solid state relays, can contribute to the implementation of this forward-looking vision.

Power solid state relays with diagnostics enable diagnostics to be carried out and can thus signal any possible problem. Celduc’s solid-state relays meet all the needs of machine builders as well as Industry 4.0.

Three-phase Solid State Relays

SMB8670910 with an auxiliary contact

An auxiliary contact allows to detect various failures on the load (opened) or on the SSR (short-circuited). Status (static output) is normally closed without failure on the relay and the load. In case of failure, the status is opened.
The status outputs can be chained for a group status information.

Typical applications : 3 phase applications where the problem must be detected immediately because of high speed process (e.g. packaging of food or medical industry)

SGT8650810 with Temperature Alarm

The temperature Alarm detects over temperature of the device and reset below 70°C. If the preset temperature limit is exceeded, the temperature switch opens and the solid state relay is switched off.

Typical application : 3 phase heating

SMCV SMCW : Three-phase AC soft starters

This better balance of and less interference on starters that you can find on the market, has also some diagnostics functions : of the network, load and product status. These diagnostic and self-test functions are here to inform people involved in the machine maintenance and to reduce the cost and the delay to restart the production.

Single phase Power SSRs with Diagnostics

Our range of diagnosis relay comes in celpac housing (ready to use) with our SILD and okpac® range (to mount on heatsinks) with our SOD and SOI.

SOD/SILD ranges

These relays inform the user of the load status (resistive load), the output of the relay and the network through an NC (Normally Closed) diagnostic contact.

The diagnostic function does not require an external power supply (celduc® patent) The contacts of various relays can be placed in a series. It is possible to use these relays for a diagnosis in a three-phase system, star wiring without neutral.

Typical applications : Applications where the problem must be detected immediately because of high speed process (e.g. packaging of food or medecine)

More information needed ? SOD range – SILD range

SOI range

Our SOI range includes a current transformer (CT) as well as a contact for signalling and therefore enables the switching of the load current by giving only the information of the presence of the output current which must then be interpreted by the user or the system.

These ranges suit any heating application where reliable and precise maintenance of temperatures is crucial to the quality of the end product. Typical applications include plastic machinery such as injection machines, extrusion machines and PET blow moulding machines, packaging/wrapping machinery, sterilisation machinery, drying tunnels …

ESUC current monitoring module : 1 relay for several loads + compact and ready to use solution

This optional module is pluggable directly on SU / SUL / SUM Solid State Contactor and permanently measures the load current.

This is possible to make a diagnostic up to 5 heating elements in parallel.

The current value is compared to a reference value which has been stored during initialisation by means of the “Teach “ push button or “external Teach” input.

Typical applications : Application where heating zones are composed of several heaters (e.g. floor heating in trains)

For more information about its installation and uses, please watch our tutorial video

ECOM module with temperature controller PID, current Monitor and communication interface in one unit : for reading the current and alarms via a communication interface

ECOM0010 combined with our SU/SUL is a compact solution providing a communication interface, a current monitoring and a PID temperature controller.

The ECOM is the most compact solution available on the market that incorporates the latest measuring and control technology.

By reducing wiring costs and minimizing the size of electrical cabinets, this solution is the answer to your needs.

Typical applications : Application where the master must get the load current values of many heating zones (e.g. blow film machines)
