05 / BUYER FAQ
Engineering checks for X-AI 32 01
QCan HIMA X-AI 32 01 be exchanged with X-AI 32 02 without changing the application?
➤Not as a blind swap. The 32 02 adds sequence-of-events capability, so hardware assignment and application behavior must be reviewed.
QWhy can HIMA X-AI 32 01 draw up to 1.5 A?
➤That value covers the module under the stated transmitter-supply short-circuit condition; normal demand depends on powered loops and field loading.
QWhich connector board must be retained with HIMA X-AI 32 01?
➤Use only an X-CB variant approved for the intended single or redundant termination arrangement and connector style.
QWhat happens when many HIMA X-AI 32 01 transmitter supplies are overloaded?
➤The module supervises loop power. If more than twelve supplies remain shorted for over three seconds, the common transmitter supply switches off and attempts recovery after the overload clears.
