Honeywell has tested this output at 9.8A at PF = 0.5, 58.8A inrush for 100,000 cycles
(EN298 approval does not require this test).
d
Total load current, excluding Burner/Boiler Motor and Firing Rate Outputs cannot exceed 5A, 25A inrush.
e
Total load current, excluding Burner/Boiler Motor and Firing Rate Outputs cannot exceed 5A, 25A inrush for 250,000
cycles.
f
Can also be 24 Vac, 3A at PF = 0.5.
g
Transformer does not apply to UV flame sensor models C7061A1020, C7061A1079 and C7061F1003 (combined with
R7861-series flame amplifiers), which have internal selectable terminal block to connect 230V shutter output directly.
