JOHNSTONE SUPPLY

Description:

• Auxiliary shaft has same torque and dead weight rating as power end shaft — the auxiliary shaft of a normally closed motor can be used for valve or damper linkages in a normally open application
• Wiring box provides protection from driving rain (rated NEMA-3)
• Reduced power consumption may allow smaller transformer use
• Configurable to replace many previous motors
• Double ended shafts; 3/8" square, ambient temperature ratings of -40°F to +150°F
• Motors are non-spring-return unless otherwise noted
• L39-855 and L39-857: Two-position, spring-return motor used to operate dampers and valves; integral helical spring returns motor shaft to fully closed position on power interruption; one auxiliary switch
• L86-163: Reversing, three-wire SPDT or floating control motor used to operate dampers and valves; adjustable stroke
• L86-919: Proportional motor used to operate dampers and valves when used with a modulating DC voltage source
• L39-861: Proportional motor used to operate dampers and valves when used with a modulating 4-20mA control signal
• L39-862: Proportional motor used to operate dampers and valves when used with a modulating 4-20mA control signal; includes two auxiliary switches
• L86-164: Two-position, spring-return motor used to operate dampers and valves; integral helical spring returns motor shaft to fully closed position on power interruption
• L86-165, L39-870, L39-871, L86-166, L86-167, L39-874 and L86-168: Reversing, proportional motor used to operate dampers and valves
• L39-870: Includes one auxiliary switch
• L39-871: Includes two auxiliary switches
• L86-167: Both power and auxiliary shafts are tapped
• L39-874 and L86-168: Integral helical spring returns motor shaft to fully closed position on power interruption
