YOKOGAWA YS1500-121/A06
Product Introduction:
The YS1500-121/A06 is a compact single-loop controller from Yokogawa’s YS1500 series. It is the smallest model in the YS series, featuring a 1/16 DIN (48 × 48 mm) form factor. The /A06 suffix indicates a specific configuration. The YS1500 provides PID control with universal input in an ultra-compact package suitable for space-constrained panel installations.

Applicable Industries:
- OEM Equipment — Machine builders requiring compact controllers
- Packaging Machinery — Seal temperature, fill level control
- Laboratory Equipment — Oven, incubator temperature control
- HVAC — Damper actuator control, small zone temperature control
- Analytical Instruments — Process variable control in analyzer systems
Installation Requirements:
- Panel cutout: 45 mm × 45 mm for 1/16 DIN mounting
- Use twisted-pair shielded cable for all analog inputs
- Maximum cable length: 50 m for mA signal, 100 m for TC (with compensated cable)
- Ensure 24 VDC supply ripple ≤ 5%
Precautions:
- Do not exceed rated input signal range — will damage input circuitry
- Use correct polarity for DC voltage and current inputs
- Do not apply more than 30 VDC between any terminals
- Allow 15 minutes warm-up for stable operation
