User manual - ATR224 - DRR224 - 11
ATR224-12ABC
For thermoresistances PT100, Ni100.
• For the three-wire connection use wires with the same section.
• For the two-wire connection short-circuit terminals 17 and 19 for ATR224
and terminals 13 and 15 for DRR224.
• When shielded cable is used, it should be grounded at one side only.
