New release: Alternating relays and 3+1 output configuration

We are proud to announce an upgrade to our SRP-94, SRP-N118 process meters, and SUR-457 universal meter - the Alternating Relays function! SRP-94 and SRP-946 also offer a new 3× relay outputs + 1× analog output configuration and are now housed in a casing with a modern-looking black color front panel.

What is the Alternating Relays function?
It’s the alternating activation of relay outputs in a defined sequence to distribute load evenly (e.g., pumps, fans) while maintaining continuous operation of the installation. The device automatically rotates the active output on subsequent run requests or when specified criteria are met — without any need to change priorities manually.

New output configuration: 3× relay + 1× analog

To support the new function, we’ve added an option to equip the SRP-94/946 with three independent relay outputs and one analog output. This allows you to implement local on/off logic (signalling/control) while simultaneously transmitting a 4–20 mA / 0–10 V process signal to a supervisory system (PLC/SCADA).

New, modern look of the device

We’re updating the design: the previous grey front is being replaced with a modern black front panel. It will be available first on SRP-94/946, SUR-94, SWS-94/946, SRT-94; the remaining models will follow soon. The new front improves the readability and visual consistency of the product line in control cabinets.
