Yokogawa AKB331-M25 50-Pin to 50-Pin FIO Signal Cable 25m
Product Brief Description
Yokogawa AKB331-M25 is a 25-meter dedicated 50-pin shielded signal cable for CENTUM VP FIO I/O system. It is designed for 32-point DI/DO modules, connecting FIO I/O cards to matched terminal blocks like ATD5A, ARS15M relay terminal boards. Both ends adopt 50-pin dedicated connectors for stable digital signal transmission inside DCS cabinets and between cabinet and junction boxes.
Product Functions
- Transmit 24VDC digital input and digital output signals for 32-channel FIO DI/DO modules
- Dual-ended 50-pin dedicated locking connectors for quick and reliable plug connection
- Full shielded cable construction to resist EMI interference in dense control cabinet environments
- Suitable for long-distance wiring between FIO rack and remote terminal junction box
- Matched with ADV151, ADV551 32-point digital modules and ATD5A terminal assemblies
- Support dry contact, pulse and interlock on-off signal transmission for safety logic loops
Application Scenarios
- Petrochemical, refinery and natural gas plant CENTUM VP interlock control systems
- Thermal power boiler and turbine pump, solenoid valve and limit switch signal wiring
- Chemical, pharmaceutical and water treatment sequence control cabinet wiring
- FIO I/O cabinet connection for 32-channel DI/DO modules and relay terminal units
- DCS cabinet renovation, I/O expansion and spare cable replacement projects
FAQ
Q: What does AKB331-M25 mean?
A: AKB331 = 32-point FIO DI/DO dedicated signal cable, 50pin to 50pin; M25 means nominal length is 25 meters. Other common lengths: M001, M002, M005, M010, M015, M020.
Q: What is the difference between AKB331 and AKB337?
A: AKB331 is for 32-channel DI/DO modules such as ADV151 / ADV551; AKB337 is for 64-channel high-density DI/DO module ADV161.
Q: What is the difference between AKB331 and KS1 cable?
A: AKB331 is 50pin cable dedicated for 32-point DI/DO; KS1 series is KS connector cable for analog modules AAI143 / AAI543 with HART signal.
Q: Can I replace it with ordinary multi-core shielded cable?
A: Not recommended. It uses proprietary 50-pin pin assignment and impedance matching, generic cables may cause signal loss or interlock malfunction.
Q: Is this original Yokogawa spare accessory available?
A: It is a standard FIO wiring accessory. Original new stock and refurbished units are supplied for maintenance of existing CENTUM VP DCS systems.
