Product Details
The Yokogawa AIP571 S1, also cataloged as the AIP571 Analog Input Module, operates as a dedicated hardware component for multi-channel analog measurement and signal conditioning within Yokogawa process control platforms. It converts voltage, current, thermocouple, and RTD sensor inputs into high-resolution digital values transmitted over Modbus RTU RS-485 interfaces.

Cold Junction Compensation (CJC) and 4-20 mA Loop Isolation
The AIP571 S1 incorporates channel-to-channel isolation circuits to prevent ground loops and shield digital logic from common-mode electrical noise across all 8 input paths. For temperature measurement loops, the module integrates cold junction compensation (CJC) algorithms alongside linear scaling for thermocouple and RTD sensors. When processing 4-20 mA current and programmable voltage signals, internal signal filtering conditions raw analog transients before 16-bit analog-to-digital conversion, ensuring data integrity over Modbus RTU telemetry buses.
Frequently Asked Questions
Q: How does the AIP571 S1 handle cold junction compensation for thermocouple inputs?
A: The module utilizes onboard temperature sensors to perform continuous cold junction compensation across its input terminal block, correcting voltage offsets in real time.
Q: Can each of the 8 input channels be configured for a different sensor type?
A: Yes, each channel supports individual software programming to accept distinct voltage, current, RTD, or thermocouple input ranges.
Q: What mounting hardware is required to install the AIP571 S1 module?
A: The module features an integrated locking latch designed for standard 35 mm DIN-rail mounting inside industrial enclosures.
Field Installation Guidelines
- ESD Protection: Connect an anti-static wrist strap to cabinet earth ground prior to handling or wiring the module assembly.
- DIN-Rail Mounting: Snap the module firmly onto the 35 mm DIN rail until the spring-loaded clip locks into place. Verify rigid mechanical mounting.
- Shield Grounding: Ground all signal cable shields at a single point on the cabinet instrument earth bar to prevent circulating ground loop currents.
- Wiring Separation: Maintain physical separation between low-voltage analog input leads and high-voltage AC distribution wiring within cabinet wireways.
