The Yokogawa AIP503 is a single-channel, DC input analog isolator (also known as a signal conditioner or converter) from Yokogawa's earlier line of industrial instrumentation. It is designed to be mounted on a universal AIP series backplate, which allows for high-density installation in control panels.
Key Specifications
Category Specification Details
Model AIP503
Input Type: Analog DC Current or Voltage (specific range determined by model suffix and internal jumpers)
Common Standard Ranges:
- Current: 4-20 mA, 0-20 mA, 10-50 mA
- Voltage: 1-5 V, 0-5 V, 0-10 V, ±10 V
Input Impedance: Current: 25 Ω (for 4-20 mA); Voltage: 1 MΩ
Output Type: Analog DC Current
Standard Range: 4-20 mA DC (two-wire transmitter output)
Load Resistance: 0-550 Ω (for 4-20 mA output, dependent on power supply voltage)
Power Supply Rated Voltage: 24 V DC ±10% (supplied to the AIP backplate)
Power Consumption: Approx. 1.2 W
General Performance Accuracy: ±0.1% of span
Temperature Effect: ±0.015% of span per °C
Response Time: ≤ 2.5 seconds (to 99% of final value)
Isolation: 3-way isolation between Input, Output, and Power Supply.
Dielectric Strength: 1500 V AC @ 50/60 Hz for 1 minute (between all isolated ports).
