alue measured under standard operating conditions (section 19.11).
2 Does not include the reference junction temperature compensation accuracy.
3 This module supports Au7Fe with 0.07% metal content with respect to gold.
6. Typical value represents a typical or average value. It is not strictly warranted.
WARNING
• Do not apply input voltage exceeding the maximum input voltage or allowable common
mode input voltage.
• T
o prevent the possibility of electric shock, be sure to furnish protective earth grounding of
the DL850/DL850V.
• T
o prevent the possibility of electric shock, be sure to fasten the module screws.
Otherwise, the electrical and mechanical protection functions will not be activated.
