【 Important Notice 】
According to ABB’s official channels and major distributors (RS Components, etc.), this model (1SVR011718R2500) is currently discontinued and the manufacturer is no longer stocking it. If there is a need for replacement, it is recommended to contact an authorized ABB distributor to confirm the latest replacement model (Phoenix Contact MINI MCR series is one of the officially recommended replacement solutions).
[Product Positioning]
1SVR011718R2500 is an analog current to current (I/I) signal converter in the ABB CC-E series, belonging to the signal conditioner category in ABB’s low-voltage product line. Model interpretation: 1SVR is the prefix of ABB signal conditioner series, 011718 is the I/I current conversion function code in CC-E series, and R2500 is the specific configuration version. This device isolates, converts, and conditions 4-20mA current signals before outputting them. It is a digital integrated alternative to traditional independent signal isolators and independent transmitters, and is designed for industrial automation scenarios that require precise isolation and transmission of current signals.

[Core Function]
This module simultaneously undertakes the tasks of receiving analog current signals, electrical isolation, signal conditioning, and conversion output. Built in high-precision signal conditioning circuit, supports converting 4-20mA current input to 4-20mA current output (I/I configuration), and can also be configured as 0-20mA or other standard signals according to specific ordering codes. All channels are provided with electrical isolation, which can effectively suppress common mode spike interference of the frequency converter. The module adopts a plug-in terminal design, which does not require on-site adjustment after configuration, and is plug and play.
Signal conversion function (I/I configuration)
Input signal: 4-20mA current input (can also be configured as 0-20mA), supporting two-wire or four wire connections.
Output signal: 4-20mA current output (can also be configured as 0-20mA), typical load capacity of 500 Ω.
Resolution: High precision adjustment, conversion accuracy typical value ± 0.1% FS.
Conversion cycle: Typically ≤ 1ms.
Linearity: better than ± 0.1% FS.

All channels support disconnection detection and automatically trigger fault alarms when signals are lost.
Overvoltage protection: The input can withstand ± 30V continuous overvoltage without damage.
Electrical isolation
Three way electrical isolation design: isolation between power circuit and input circuit, isolation between power circuit and output circuit, isolation between input circuit and output circuit, with a typical isolation voltage of 500V DC. Ensure the accuracy and safety of signal transmission in strong electromagnetic interference environments, and protect downstream control systems from external interference.

Installation method: 35mm DIN rail, plug-in terminal design, supports horizontal or vertical installation (when installed vertically, the output load above 40 ° C is reduced to 50%).
Front panel protection level: IP20 (compatible with cabinet up to IP54).
Working temperature range: -20 ° C to+80 ° C, storage temperature -40 ° C to+70 ° C.
Auxiliary power supply: 24V DC (± 20% adaptive) or 9.6-30V DC, powered by external sources.
Typical power consumption: ≤ 1.5W.
Fanless design, no electrolytic capacitors, no moving parts, normal coating coated board, maintenance free long-term operation.
Programming and Configuration
This product is a pure hardware configuration signal converter that does not require software programming. All parameters (input range, output range, filtering time constant, etc.) are set at once through the front panel potentiometer or jumper, and do not need to be adjusted again after configuration is completed. Supports multiple standard signal combinations: 0-5V, 0-10V, 0-20mA, 4-20mA, RTD (PT100/PT1000), thermocouple (J-type/K-type), etc.
Self diagnosis and alarm
The device continuously self monitors internal faults and channel abnormalities, and reports its health status directly to the main controller. Each input supports upper and lower limit alarms, and the alarm values can be independently set. Output an alarm signal when triggering an alarm. The LED indicator light displays the real-time signal status of each channel. Once an internal fault occurs, all channels will be automatically locked and an alarm will sound.
[Typical Application]
Isolation transmission of current signals: Isolate and convert the 4-20mA sensor signals (such as pressure transmitters, flow meters, and level gauges) on site, and send them to the PLC/DCS system to eliminate ground loop interference.
Long line signal transmission: When the transmission distance is long, signal attenuation is compensated by isolation amplification to ensure remote reception accuracy.
Multi system signal allocation: One 4-20mA input is converted into multiple 4-20mA outputs to achieve signal division into multiple.
Electromagnetic valve/actuator drive: Output 4-20mA signal to control the opening of the regulating valve, achieving closed-loop regulation such as constant pressure water supply and constant temperature control.
Suitable for industries such as electricity, oil and gas, chemical, metallurgical, water treatment, and building automation.
