Frequently Asked Questions (FAQ)

• Q: What is the difference between ADV151-E50 and ADV151-P50?
  A: The ADV151-E50 includes SOE capture (Suffix E), while the P50 model provides pulse counter functionality instead.
• Q: Can I mix sink and source wiring on the same module?
  A: Yes, the ADV151-E50 supports both sink and source configurations per channel, giving you flexible field wiring options.
• Q: What cable should I use for connection to Yokogawa terminal boards?
  A: Use the dedicated AKB331 cable or the MIL connector cable for reliable, high-density connections.
• Q: Does this module support hot-swap replacement?
  A: Yes, the ADV151-E50 supports hot-swapping in Yokogawa Centum and ProSafe systems.
• Q: What is the typical power consumption of this module?
  A: It consumes about 2.5 W (500 mA at 5 V DC) – a low value that minimizes cabinet heat.
• Q: How do I interpret the suffix codes for this module?
  A: E = SOE enabled, 5 = no display/no explosion protection, 0 = basic type. Option /D5A00 adds a KS cable adapter.
• Q: Is this module suitable for use in SIL-rated safety loops?
  A: The ADV151-E50 is a standard DI module. For SIL applications, please refer to Yokogawa's ProSafe-SIL rated modules.
