Yokogawa YS17YS1700-000/A
Model Number: YS17YS1700-000/A
Product Introduction:
The YS17YS1700-000/A is a specific configuration variant of the YS1700 series isolated signal converter. The suffix “-000/A” indicates a standard 4–20 mA to 4–20 mA conversion with no special options (000) and revision A (/A) of the product. It provides galvanic isolation for process signal transmission in industrial instrumentation.

Material Composition:
- Housing: Flame-retardant polycarbonate (UL94 V-0)
- Terminals: Phosphor bronze, tin-plated
- PCB: Conformal-coated FR-4
Structure Characteristics:
- 22.5 mm ultra-slim DIN rail form factor
- Spring-clip terminal blocks (input and output)
- Front-panel zero/span potentiometers (covered with cap)
- Single LED power indicator
Working Principle:
Identical to the YS1700 base model. Input 4–20 mA signal is converted to voltage, passed through an isolation amplifier, then converted back to 4–20 mA output. The isolation barrier (optical or transformer-based) breaks DC continuity between input and output, eliminating ground loop currents while preserving signal integrity.
Advantages & Highlights:
- Same core performance as YS1700 base model
- -000/A suffix confirms standard configuration (no custom options)
- Ultra-compact design saves panel space
- Zero maintenance operation (no moving parts, no calibration drift under normal conditions)
Applicable Industries:
- Same as YS1700 base model (Oil & Gas, Chemical, Water, HVAC, Food, Mining)
Installation Requirements:
- Identical to YS1700 base model
- DIN 35 mm rail mounting
- Separate ground references for input and output loops
- Shielded cable recommended
Usage Precautions:
- Identical to YS1700 base model
- Do not bridge input and output grounds
- Do not exceed 600 Ω loop load
- Do not apply > 32 V DC
