TCA Electronic Controller
The TCA at the heart of the
EH Fan Drive System, is a
rugged, fully encapsulated
digitally programmable con-
troller specially designed for
mobile environments.
It is prepared for CANbus
communications on a ve-
hicle network. Software for
controlling the EH Fan Drive
System is loaded in the con-
troller memory at the factory.
Control software parameters
are adjusted via RS 232 hook-
up to a laptop computer.
The TCA controller is available
for both 12 V or 24 V vehicle
power systems. With 5 con-
figurable inputs and 2 Pulse
Width Modulated (PWM)
outputs, the TCA can inter-
face with a variety of system
components and drive up to
two electro-hydraulic valves.
Two Channel Amplifier (TCA)
EFX Electronic Controller
Eaton EFX electronic control-
lers and I/O modules provide
a full range of electronic con-
trols. With an array of control-
ler options and I/O modules,
an EFX system can address
any application need. All EFX
products are IP67 rated and
are built for harsh mobile
and industrial application
environments. The EFX line is
programmed and configured
using Eaton CONTROL F(x)™
software.
Applications
Excavators, forestry,
telehandlers, utility vehicles,
cranes, ag machinery, paving
Specifications
Four different EFX controllers
and 3 I/O expansion modules
provide analog, digital, and
frequency inputs as well as
digital, PWM, and current-
controlled outputs. Each EFX
controller has both CANopen
and J1939 interfaces.
