Load Curve 1 Electrical durability of contacts on resistive loading millions of operating cycles X Current broken in A Y Millions of operating cycles A.C. Load Curve 2 Reduction factor k for inductive loads (applies to values taken from durability curve 1). X Power factor on breaking (cos ϕ) Y Reduction factor k Example: An LC1-F185 contactor supplied with 115 V/50 Hz for a consumption of 55 VA or a current consumption equal to 0.1 A and cos ϕ = 0.3. For 0.1 A, curve 1 indicates a durability of approximately 1.5 million operating cycles. As the load is inductive, it is necessary to apply a 6 reduction coefficient k to this number of cycles as indicated by curve 2. For cos ϕ = 0.3: k = 0.6 The electrical durability therefore becomes:1.5 10 operating cycles x 0.6 = 900 000 operating cycles. 14 D. C.

When control contact C re-opens, timing T starts. At the end of the timing period, the output(s) R revert(s) to its/their initial state. The second output can be either timed or instantaneous. Function: 1 Output Function: 2 Outputs 2 timed outputs (R1/R2) or 1 timed output (R1) and 1 instantaneous output (R2 inst.) 16 Product data sheet RE7RM11BU Technical Description Legend Relay de-energised Relay energised Output open Output closed C Control contact G Gate R Relay or solid state output R1/R2 2 timed outputs R2 inst.The second output is instantaneous if the right position is selected T Timing period Ta - Adjustable On-delay Tr - Adjustable Off-delay U Supply RE7RM11BU is replaced by: Relay Output RE22R1CMR Off-delay Timing Relay - 0.05s…300h - 24…240V AC/DC - 1C/O Qty 1 Reason for Substitution: End of life | Substitution date: 01 January 2017 17
