DI6 DI5 Digital inputs, If programmed as digital inputs, same characteristics as DI1 to DI4.
DI5 can be programmed as pulse input 20 kpps (pulse per second).
DI6 can be used as PTC (Positive Temperature Coefficient) using SW2 switch (see page 89 of manual).
Trip threshold: 3 kΩ, reset threshold: 1.8 kΩ
Short-circuit detection threshold < 50 Ω
