Output Unit Characteristics
Relay unit life expectancy Mechanical: 10,000,000 operations min.
Electrical: 100,000 operations min.
Current Transformer Characteristics
Max. heater current 50 A, single-phase

±
1 digit max.
Heater current setting range 0.1 to 49.9 A* (in units of 0.1 A)
Min. detectable ON time 200 ms**
*Heater burnout is not detected when current is set to 0.0 A; the burnout alarm will be automatically turned ON when current is set to 50.0
**When the control output is ON for less than 200 ms, heater burnout is not detected and heater current is not measured.
