Lathem Dukane 24A715 - Manual (Page 45)

Please note that the relay contacts used in the CLK2 circuit are rated at 10 amps. The
combined load of the correction circuit and the run circuit should not exceed 8 amps. In
general, 20–35 analog clocks can be operated on a single string. This number depends on
the clock style and the distances involved. To estimate clock loads for Dukane 24SS se-
ries clocks, see the Dukane Analog Clock Installation Guide (document number
402-455).
