Modutrol IV™ Motor Transformer Kits

SERIES 2—50017460-001, 50017460-003

APPLICATION

The 50017460-001, -003 transformer kits are used to

convert line voltage to 24 Vac to power Honeywell

Modutrol IV Series 2 motors. The 50017460-001 kit

provides 24 Vac isolation, mainly for M734 and M934

replacement motors. See Table 1. Color-coded taps on

the transformer primary leads permit selection of 24 Vac,

120 Vac, or 230 Vac to match the power supply. See

Table 2. Each assembly includes a transformer and 2

transformer mounting screws. The barrier strip in the

motor’s wiring box separates line voltage wiring from low

voltage wiring.
