Connection type 2-wire, 3-wire and 4-wire
Wire resistance per wire (max.) 50 Ω
Input current < 0.15 mA
E󹪜ect of the wire resistance (with 3-wire and 4-wire connec‐
tions)
< 0.002 Ω / Ω
Cable, wire-wire capacity Max. 30 nF (Pt1000 & Pt10000 IEC and JIS +Ni1000 &

Fault detection, programmable None, short-circuited, broken, short-circuited or broken
Note: When the low limit for the con󹪝gured input type is below the constant detection limit for short-circuited inputs, the
detection of short circuits is disabled regardless of the con󹪝guration of the fault detection.
Detection limit for short-circuited input 15 Ω
Fault detection time (RTD) ≤ 75 ms (typically 70 ms)
Fault detection time (for 3-wire and 4-wire) ≤ 2000 ms
