Hello everyone, I am in search of a suitable alternative for an outdated Omron smart relay that a client of ours has been using. The Omron smart relays they have are starting to malfunction, and since they are no longer in production, we are considering switching to Zelios as a replacement. However, we have encountered a compatibility issue with the NPN inputs of the Omron relays which the Zelios do not support. Does anyone have any recommendations for a suitable replacement option? The part number for the Omron ZEN smart relay is 20C1DR-D-V2. You can find the datasheet for this product here: https://www.mouser.com/datasheet/2/307/zen_ds_e_5_2_csm106-1109483.pdf.
Are you looking for a smart relay option? The CP1L series PLC from Omron offers a compact and cost-effective solution with precise specifications.
While it's not necessary for the relay to be smart, it must have durable relay outputs capable of handling a minimum of 8A. Although we have thought about utilizing a PLC with external interface relays, the upgrade process would be more time-consuming and expensive. However, this may ultimately be the best solution for our needs.
For systems with 8 inputs and 4 outputs or fewer, the Micro810 2080-LC10-12QWB is a suitable option to consider. The inputs are compatible with both source and sink, and all four output relays can handle up to 8A. Upon further research, it was found that the M810 line now offers modules with a higher IO count than the 12-point modules previously available. Some older models may have included two 8A and two 4A relays, which were not present in the newer brochure examined. While the CCW software has received criticism, I find it useful for applications involving the M810. Additional features such as an added display for status and troubleshooting messages enhance the functionality of the M810. A USB interface module is required for programming purposes.
The IO count requirement is 12 inputs and 8 outputs. Therefore, the base unit must meet this criteria or be able to work with expansion modules. Further research revealed that the M810 line has expanded to offer higher IO counts beyond the 12-point modules previously used. It seems that Rockwell's website only displays the 12 IO model, but if a Micro810 model meets the IO requirements, it would be a viable option to consider.
When it comes to switching loads with an 8Amp relay, it's important to consider the type of load you are dealing with. While an 8Amp relay may be suitable for an 8Amp resistive load, it may not be as effective for switching an inductive or capacitive load of the same amperage. The same goes for AC and DC inductive loads. It's crucial to determine the nature of the load you are working with before pushing an output relay to its limits. While relays are relatively inexpensive and easy to replace, PLCs and Smart Relays can be more costly and difficult to find replacements for if they become obsolete. So, it's important to carefully assess your load and consider the long-term implications of your relay choice.
Hi there, we faced a similar issue last year when we were migrating from some discontinued Omron relay models. We switched to Siemens LOGO! series, given that they also come with an intuitive software for programming and debugging, just like Omron. These relays are pretty reliable and support both PNP and NPN inputs, thus it could possibly solve your compatibility issue. I'd suggest you to review their specifications according to your requirement, I believe you'll find a suitable LOGO! model as a valuable replacement. Do remember to tally the I/O count and voltage requirements for a efficient swap.
I understand your predicament, and it's quite a challenge when certain models go out of production. You may want to consider the Siemens LOGO! Series smart relays as an alternative. They have a wide compatibility range for different types of sensors (both PNP and NPN), which might resolve your issue. They're user-friendly, compact, and feature-rich too. It's worth researching this product; here's the link to their datasheet for your convenience: https://cache.industry.siemens.com/dl/files/821/109741821/att_96417/v1/LOGO8_datos_en.pdf. Remember to verify the total Analog / Digital Input and Output channels you may need as per your application. Good luck!
