ABB 1SVR040011R2500 CC-U/STDR Universal Signal Converter

Product Description

The 1SVR040011R2500 (CC-U/STDR) is a universal analog signal converter from ABB CC-U series. It accepts standard voltage and mA input signals and converts threshold values into relay switch outputs. It features three-way galvanic isolation, powered by 110–240V AC or 100–300V DC, with two independent threshold relay outputs. It adopts DIN rail mounting and pluggable terminals, widely used for signal monitoring and limit alarm in industrial control systems.

Features

• 7 configurable input signal ranges for standard voltage and current signals
• Dual threshold relay outputs, each with one SPDT changeover contact
• Independent threshold and hysteresis adjustment via front potentiometers
• Three-way electrical isolation (input, output, power supply), 1.5kV isolation level
• Power supply: 110–240V AC / 100–300V DC wide range
• DIP switch configuration for open/closed circuit working mode
• LED indicators for power status and relay output status
• DIN rail installation, quick pluggable screw terminals for wiring
• Short-circuit protected output circuit, strong anti-interference performance

Application Scenarios

• 4-20mA / 0-10V analog signal limit alarm and switching control
• Water treatment, chemical and petrochemical process monitoring cabinets
• Fan, pump pressure and flow threshold interlock protection
• Power distribution and energy management signal acquisition system
• PLC and DCS signal isolation and threshold triggering

FAQ

Q: What is the model name of 1SVR040011R2500?
A: The official model is CC-U/STDR.

Q: How many relay outputs does it have?
A: It has 2 threshold relay outputs with SPDT contacts separately.

Q: What is the function of three-way isolation?
A: It isolates input signal, power supply and relay output to eliminate ground loop interference and protect backend equipment.

Q: Can I adjust the alarm hysteresis?
A: Yes, threshold and hysteresis of two channels can be adjusted independently on front panel.
