Description
Product Overview
The ABB 1SVR040011R2500 is a CC-U/STDR universal analog signal converter designed to monitor industrial voltage and current signals and trigger relay outputs when configured thresholds are crossed. It is used in control panels where analog measurements need to be converted into discrete switching actions, such as high/low signal alarms, process limits, and equipment status interlocks. Rather than acting as a PLC or DCS controller, it provides a dedicated signal-monitoring function that can operate alongside a larger automation system.
The unit supports seven selectable input ranges: 0–1 V, 0–5 V, 0–10 V, ±10 V, 1–5 V, 0–20 mA, and 4–20 mA. Two threshold relay outputs provide one changeover contact each, with separate front-panel adjustments for threshold and hysteresis. Lateral DIP switches configure the input range and open- or closed-circuit operating principle. Three-way electrical isolation separates the relevant circuit sections, while indicator LEDs show supply status and relay state. The rated control supply is 110–240 V AC or 100–300 V DC, so the supply specification must be checked carefully before wiring.
For maintenance engineers, the practical checks are the input signal type, selected DIP-switch settings, threshold and hysteresis adjustments, relay contact ratings, and the required supply voltage. The published response time is approximately 10 ms, with repeat accuracy listed at ±0.5% of full scale under constant parameters. The module is 22.5 mm wide and mounts on a DIN rail. ABB lifecycle documentation lists the CC-U product line as discontinued, so buyers planning a replacement should confirm availability and evaluate any proposed alternative against the original electrical and functional requirements. Do not assume that a similarly sized signal conditioner provides the same isolation or relay behavior.
Product Introduction
A 4–20 mA process signal often needs to trigger a discrete alarm without adding another PLC logic point. The ABB CC-U/STDR 1SVR040011R2500 handles that task with two independently adjustable threshold relays, configurable hysteresis, and three-way electrical isolation.
For a panel retrofit, check the actual signal range and the control supply before swapping the module. Since the CC-U line is listed as discontinued, verify replacement availability and confirm that any proposed substitute matches the required switching logic, contact ratings, and isolation.

Frequently Asked Questions
1. What does the ABB CC-U/STDR do?
It monitors a selected analog voltage or current signal and operates two relay outputs according to configured thresholds. This is useful for high/low alarms, process limits, and discrete interlocks where dedicated signal monitoring is preferred over adding PLC logic.
2. Can it accept a standard 4–20 mA transmitter signal?
Yes. The 4–20 mA range is one of its documented input settings. Configure the appropriate DIP switches and threshold potentiometers, and verify the wiring and input polarity before energizing the module.
3. Can I hot-swap this module?
Do not assume hot-swap capability. Isolate the supply and relevant field circuits in accordance with the panel’s electrical safety procedure before removing the converter. Confirm that disconnecting its relay outputs will not create an unintended alarm, interlock, or process-control condition.
4. Does the CC-U/STDR support firmware v3.1?
Firmware v3.1 compatibility is not applicable as a verified feature of this analog signal converter. Its input ranges and operating behavior are configured through DIP switches and front-panel potentiometers, rather than a documented firmware-loading procedure. If v3.1 refers to the connected controller or engineering system, check that separate equipment’s version requirements.
5. Can the relay outputs switch any 4 A load?
No. The permissible current depends on the contact utilization category, voltage, and load characteristics. Published ratings differ for AC-12, AC-15, DC-12, and DC-13. Check the applicable contact rating for the actual load, especially if it is inductive, and use an appropriately rated interposing relay where required.
6. Is 1SVR040011R2500 still in production?
ABB lifecycle documentation lists the CC-U line as discontinued. Confirm current availability and any manufacturer-approved replacement before planning a new design or a long-term maintenance strategy. Do not assume that another CC-U model has identical functionality.
7. What should I verify when purchasing a replacement?
Confirm the full order number, supply voltage, configured input range, relay contact arrangement, dimensions, and isolation requirements. Request clear nameplate photographs, condition details, available functional-test records, and written warranty terms. For used or refurbished stock, ask whether both threshold channels and relay contacts were tested. Confirm actual condition with supplier before purchase.
