5X00121G01

FAQS

• Which electronics module can use Westinghouse 5X00121G01?
  This RTD personality module is specified exclusively for the 5X00119G01 electronics module.
• What RTD wiring modes are terminated by Westinghouse 5X00121G01?
  Its channel terminals support the documented three-wire and four-wire RTD connections.
• How many sensor circuits are presented on Westinghouse 5X00121G01?
  The personality module provides field connections for eight RTD channels.
• Which terminal functions appear on each Westinghouse 5X00121G01 channel?
  The documented field interface includes +IN, -IN, current source, return and shield connections.
• Are PS+ and PS- used on Westinghouse 5X00121G01?
  No. The auxiliary PS+ and PS- terminals are not used by this RTD personality module.
• Why must source and sense conductors remain distinct on Westinghouse 5X00121G01?
  The RTD measurement depends on the documented source, return and input arrangement, especially when a four-wire channel is selected.
• What would an incorrect three-wire/four-wire selection cause on Westinghouse 5X00121G01?
  A mismatch between terminal wiring and channel configuration can produce an erroneous resistance value or a channel fault at the 5X00119G01 electronics.
• How should Westinghouse 5X00121G01 field wiring be accepted?
  Trace every conductor to its +IN, -IN, source, return or shield terminal and confirm the paired electronics reports a stable value on all eight channels.
