Some applications require a high force capacity in a
relatively small package. In order to achieve this solenoids
typically have been designed with a (2) section coil, "high
current pull-in coil” and a "low current, continuous duty
hold-in coil.” This solution required that the "high current
pull-in coil" be electrically disconnected once the solenoid
had pulled in and only the "low current hold-in coil” be left
energized. With the S500-A60 module it is not necessary to
disconnect the "high current pull-in coil” after the solenoid
has pulled in. The module has been designed to work properly with
either a (2) section coil or a (1) section coil. The module operates
in the following manner. When a remote control signal is applied to
the Aux input of the module it applies full voltage to the solenoid
coil or coils. After the actuation time (approximately .5 sec) the
module reduces the output voltage to the solenoid to 13% to 16% of
the input voltage for continuous duty. This reduced voltage level is
applied to the coil or coils until the control signal is removed.
The flexibility to operate with either (2) section or (1) section
coils allows the module to be used as a replacement for older relay
style modules. Note the wiring connections may not be the same as
older relay style modules.
This Trombetta module allows you to incorporate (2) coil section
solenoids or (1) coil section solenoids into your applications.
These modules accept your 3 wire switched input, (12V or 24V) and
applies this input to the solenoid. The S500-A60 module is a cost
effective unit that does not require an additional contactor for 24V
applications. This module is provided with stainless steel terminal
screws standard and tin plated brass terminals maintaining contact
integrity in harsh environments. |
