The AIP171 is a transceiver control module designed for Yokogawa’s distributed control systems. Its job is to manage communication between transceivers and repeaters on the V‑Net network, maintaining signal integrity, enabling remote / extended connections, allowing diagnostic features, and supporting redundancy. It is built for industrial settings, with moderate environmental tolerances and a compact physical form.
Acting as a communication intermediary (transceiver / repeater control) in DCS networks
Extending communication range of V‑Net links or balancing signal strength over longer distances
Environments where reliability and diagnostics are required (e.g. power plants, oil & gas, chemical process industries)
Systems where space is constrained, but modular replacement / maintenance is expected
Upgrades or retrofits of existing DCS installations that need enhanced communication modules
Compact size and light weight (≈ 0.20 kg) simplifies installation and reduces mechanical load
Standard 24 V DC operating power, common in control cabinets
Temperature range that covers many typical industrial ambient conditions (‑20 to +60 °C)
Communication interface options (V‑Net, RS‑485 etc.) provide flexibility
Diagnostic / status reporting helps detect communication faults early
Physical dimensions make it easy to replace or add to existing card slots
Below are tables comparing similar modules in the same functional domain, and other popular modules from the same brand for context.
| Model | Key Specs / Differentiators | Dimensions / Weight |
|---|---|---|
| AIP171 | Transceiver control; 24 V DC; moderate environmental requirement; V‑Net / RS‑485 interface | 12.7×17.8×2.5 cm; 0.20 kg |
| AIP578 | Optical link / fiber optics capable; extended distance communication | Slightly larger; weight ~0.30‑0.4 kg |
| AIP571 | High‑performance electrical transceiver module; possibly higher data rates or redundancy | Similar footprint; heavier due to more interface hardware |
| AIP501 / AIP502 | Communication / interface modules; possibly protocol conversion or bus couplers | Comparable weight; possibly more depth |
| ACP71 | PROFIBUS or other field‑bus card; supplement to V‑Net communication in multi‑protocol environments | Size & weight comparable; function is bus‑specific rather than generic transceiver control |

Here are 10 questions & answers about AIP171, phrased in a non‑AI style, technical / field oriented.
Q1: What power supply voltage does AIP171 require?
A1: It requires 24 V DC (standard supply in many Yokogawa control cabinets).
Q2: What is the operating temperature range?
A2: Typically ‑20 °C to +60 °C in non‑condensing conditions.
Q3: How heavy is AIP171 & what are its physical dimensions?
A3: Weight is about 0.20 kg. Dimensions are approximately 12.7 cm wide × 17.8 cm high × 2.5 cm deep.
Q4: What communication interfaces does it support?
A4: It supports V‑Net, RS‑485; some listings also include possible RS‑232 or Ethernet in certain versions.
Q5: What is the module’s role in network communication?
A5: It acts as a transceiver control module or repeater / relay of signals between V‑Net repeaters and transceivers, helping maintain network integrity and reach.
Q6: Can it be used for redundant communication networks?
A6: Yes—some configurations support redundancy (pairing modules) to improve reliability in case of module or link failure.
Q7: What is the acceptable storage temperature for the module?
A7: Storage temperature is around ‑20 °C to +70 °C in many listings.
Q8: How good is its diagnostic or status indication capability?
A8: It includes status or diagnostic capability in many versions, enabling detection of communication faults or module status visually or via system monitoring.
Q9: Are there special mounting requirements?
A9: It is card/module style; mounted in racks or DCS cabinets; attention to ventilation and ambient conditions helps ensure long life.
Q10: What is the maximum distance / performance capability for communication?
A10: Data rate is reportedly up to 10 Mbps in some listings; the transceiver link helps extend range of V‑Net communication through repeaters. Exact maximum distance depends on cable type, network design, and environmental conditions.
