•
Tachometer inputs for closed loop
speed control
•
Potentiometer input for position (servo
mode)
•
External temperature sensor inputs
•
User defined purpose (RS232 mode
only)
•
One Switch input configurable as
•
Emergency stop command
•
Reversing commands when running
vehicle inverted
•
Up to 2 general purpose outputs for acces-
sories or weapon
•
One 24V, 2A output
•
One low-level digital output
•
Up to 2 digital input signals
•
8 RC pulses outputs for connection to
additional Roboteq slave controllers or RC
servos
Built-in Sensors
•
Voltage sensor for monitoring the main 12
to 40V battery
•
Voltage monitoring of internal 12V
•
Temperature sensors near each Power
Transistor bridge
Advanced Data Logging Capabilities
•
12 internal parameters, including battery
voltage, captured R/C command, tempera-
ture and Amps accessible via RS232 port
•
Data may be logged in a PC or microcom-
puter
•
Data Logging Software supplied for PC
Low Power Consumption
•
On board DC/DC converter for single 12 to
40V battery system operation
•
Optional 12V backup power input for pow-
ering safely the controller if the main
motor batteries are discharged
•
200mA at 12V or 100mA at 24V idle cur-
rent consumption
•
Power Control wire for turning On or Off
the controller from external microcom-
puter or switch
•
No consumption by output stage when
motors stopped
•
Regulated 5V output for powering R/C
radio. Eliminates the need for separate R/C
battery.
High Efficiency Motor Power Outputs
•
Two independent power output stages
•
Dual H bridge for full forward/reverse oper-
ation
•
Ultra-efficient 2.5 mOhm ON resistance
MOSFETs

trically or software induced program failure
•
Overvoltage and Undervoltage protection
•
Watchdog for automatic motor shutdown
in case of command loss (R/C and RS232
modes)
•
Large and bright run/failure diagnostics on
7 segment LED display
