1. How can I manage a load with a 4-20mA signal? How can I proceed in case the load is an unbalanced three-phase one? (MAILTS-152)
The product families suitable for driving a load proportionally to a 4-20mA signal are the following:
• SSR19 series static relays for phase angle control
• SSR08I series static relays for phase angle control
• SSR39 series three-phase static relays for phase angle control
• Static relays for phase angle control SC1-30D … I series
• SSRSPC1 series Static Groups for analogue power control
In the case of an unbalanced three-phase load, the neutral must be connected, consequently single-phase or three-phase SSR can be used in the appropriate configuration.
2. I need to have the price list, how can I obtain it?
Use the Contact Us form on our web site which is directly seen by the Backoffice department who will reply as soon as possible.
3. How long is the life cycle (MTTF) of ELCO SSRs?
Use the Contact Us form on our web site which is directly seen by the Backoffice department who will reply as soon as possibleAs regarding our SSRs consider an indicative value between 25 and 250 years, considering a continuous use 24 hours a day at the limit of specifications. For less demanding applications the SSRs life will increase.
4. How can I connect the inputs of an SSR082-50600? (MAILTS-124)
The two inputs of this SSR are independent and both accept a voltage between 4 and 32Vdc.
If an adequate voltage is guaranteed, it is possible to drive them in series, keeping the driving current lower.
However, if we want to guarantee a higher voltage to both inputs, it is preferable to drive them in parallel.
5. How can I connect the alarm output of an SSR082W-25240AS? (MAILTS-123)
Pin 6, used to signal the error condition, is an open collector of a transistor that closes to ground (pin 4).
The input to which it will be connected will consequently require a pull-up.
It accepts a voltage from 5 to 32Vdc up to a maximum current of 100mA.
6. How can I install ELK43?
All information relating to the installation of the product are available on the manual book, which can be downloaded from the website www.elco-italy.com on the product page.
In case of an obsolete product, as the case of ELK43 series, it is possible to open a support ticket, specifying the request, at the following LINK.
7. Where can I find the technical information of the EZ14 interface?
The relative technical data sheets are available on the website www.elco-italy.com under the category Products> Relay Interface Modules.
8. How can I connect TSE-RT?
From the menu PRODUCTS on the web site, or by using the SEARCH function, it is possible to reach the pages of the individual devices or of the relative families. Here it is possible to download the relative documentation which contains all the information relating to the connections.
9. Which temperature controllers can be equipped with MODBUS-RTU and TCP / IP protocols?
On the “Temperature controllers selection chart” it is possible to identify the models that can be ordered with RS-485 (Modbus RTU) or RJ45 (Modbus TCP) respectively.
10. Where can I find the ELCO manuals online?
From the “PRODUCTS” menu on the website, or by using the DOWNLOAD function, it is possible to reach the pages of the individual devices or families, from where it is possible to download the documentation.
11. What should I do to download the ELCO software?
The SW can be downloaded from the site by following the instructions on Download> Software Guide – DOWNLOAD
12: I need an alternative to a ELCO competitor's code. How can get it?
Open an assistance ticket to our Technical Support asking for information about it.
13. How soon will I be contacted if I open a "Technical Support Request"?
Within a maximum of two working days the customer will be contacted by our technical support by email or by phone.
The ticket will be closed after the resolution of the problem has been agreed with customer or after 15 days of customer inactivity.
