Contact resistance When new mΩ 45 max.
Mechanical life time Unload 20 x 10 6 operations
Loads on relay
outputs
Resistive e.g.: heating element Electric life time : 1 x 10 5 operations min.:
- 2 A at a 240 V
- 2 A at c 30 V
with 600 operations max./hour
Inductive with
protection (1)
Capacitive
e.g.: relay, solenoid valve
e.g.: TeSys U starters, Festo
solenoid valves
Electric life time : 1 x 10 5 operations min.:
- régime inductif AC-15 : a 240 V 1 A, cos ϕ = 0,7
- régime inductif AC-15 : a 240 V 0,5 A, cos ϕ = 0,35
- régime inductif DC-13 : c 24 V 1 A, L/R = 7 ms
Use of relay outputs not guaranteed (reduction of life).
For this type of application, it is advisable to use the transistor outputs of
extension modules TM2 DDO pppp
