- Fixed 4‑20 mA input to 4‑20 mA output conversion; fine calibration of gain and offset by front potentiometers.
- Three‑way isolation protects control‑system side from field‑side interference and surge transients.
- Compact DIN‑rail installation inside control cabinets for process‑automation signal conditioning.
- Product lifecycle status: End‑of‑Life, no new production by ABB; procure spare‑parts with full part‑number.
5. Typical Applications
- Process industry: 4‑20 mA signal isolation between field transmitters and DCS / PLC analogue inputs.
- Power plant, water‑waste‑water, petrochemical control panels for ground‑loop elimination in analogue measurement loops.

6. Important Notes
- This is fixed‑range I‑I converter, not universal configurable type; input and output are locked to 4‑20 mA.
- Observe maximum output load resistance ≤ 500 Ω, excessive load will degrade signal accuracy.
- Gain‑offset trimming should be performed during commissioning for site calibration.
- Full ordering part‑number 1SVR011718R2500 must be used for spare‑part purchasing.
