MODULATING

FAILSAFE MODULATING

Feature rich J+J multi-voltage smart electric actuator with LED status light and function conversion kits.
Overview
The J3C-L20 low voltage electric valve actuator from the electric actuator manufacturer J+J offers an impressive list of standard features that include protection
against damage from over-torque or condensation, safety features, the ability to
have it’s standard on-off function changed with user friendly plug & play conversion kits, and a highly visible LED light to offer users continual actuator operational
status feedback.
The J3C Failsafe electric actuator is the same on-off J3C actuator but with a simple
to install, user friendly ‘BSR’ failsafe function conversion kit. The J3C BSR failsafe
actuator can be set to fail open or fail closed.
The J3C Modulating electric actuator is the same on-off J3C electric actuator but
this time with the quick and easy to install ‘DPS’ modulating function conversion
kit. The J3C DPS modulating actuator can be controlled by either a 4-20mA or 010V control signal and provides feedback as standard.
The LED light remains constantly lit if the actuator is able to respond to remote
commands - if it can’t, it flashes. The sequence of the flashes indicates what the
reason may be for it being unable to respond.

How this J3C electric 1/4 turn valve actuator works (on-off)
Electrically operated valves are driven by an electric actuator containing a motor and gearbox. On receipt of a continuous voltage signal (not
pulse) the motor runs and, via a gearbox in the electric actuator, rotates the valve stem. The motor stops at the desired position (usually 0
or 90 ) by an internal cam striking a micro-switch. The valve actuator remains in this position, with the voltage still applied continuously, until
switched and a continuous voltage reversing signal (not pulse) is applied, which runs the motor in the opposite direction, reversing the rotation until a separate internal cam strikes a separate micro-switch and stop the motor.
