 The current sources are supplied by the user (fusing is at the discretion of the user.)
     Either shielded or unshielded cables may be used. In noisy environments, twisted
shielded cable is recommended. Shielded cable should have a shield tied to earth ground
near the signal source end.

 Unused inputs may cause the activation of the F LED. To avoid this occurrence the
unused channels should be configured in the 0 ... 25 mA range.
 The maximum channel to channel working voltage cannot exceed 30 Vdc.

The following figure shows the ARI03010 wiring diagram.

 The module is calibrated per:
IEC Publication 751 for platinum RTDs: 100Ω @ 0 degrees C, TCR (α) = 0.00385Ω/Ω/
degrees C.
DIN 43760 for nickel RTDs
American Platinum RTDs: 100Ω @ 0 degrees C, TCR (α) = 0.00392Ω/Ω/degrees C
     Terminals labeled shield are not connected internally. Shields should be grounded at the
field device end.

 When using     
, the temperature equivalent of  the lead
resistance of one leg must be subtracted from the temperature reading.

Remote CJC can be implemented by connecting a TC (which
monitors the external junction block temperature) to channel

$ Absolute accuracy includes all errors from the internal CJC, TC – curvature,
offset plus gain, for module temperature of 0 ... 60° C. User supplied TC errors
not included.
% For Type J and K, add 1.5° C inaccuracy for temperatures below -100° C.

Zoom Selections
Push <Enter> to display and select the timeout states for each channel. Timeout
state is assumed when system control of the module is stopped.
The following figure shows the Channel X timeout state options.

Channel 4 data (0 ... 4,095 +/- 10 V, +/- 5 V, 0 ... 5 V, or 0 ... 10 V)
Selecting "Disabled" for any channel causes all others to default to that state.
Output will be what is connected to the module master override terminals, either
common or an external voltage. Output LEDs 1-4 will go out when Disabled is
selected and the module goes to the inactive state.
