Features:

• The Sentinel mounts rigidly to the Talon SRX without spacers or insulating pads, using two Talon-SRX supplied 4-40 screws.
• Input wires can be soldered directly to pads on the breakout board, or you may install header or quick-connect terminal blocks onto the breakout board by soldering them into the through-holes provided (on .1 inch centers).
• Wires are secured by threading them through wire retention holes, if desired.
• Accepts all type of encoders; open collector output, push-pull output, and PWM Index (single-turn absolute position encoders that work by pulse width modulating the Index input).
• Includes internal pull-up resistors for the A/B/I encoder inputs
• Compatible with all Talon SRX models including version 1.4

Encoder Inputs and Travel Limit Switches

• Encoder inputs supported: A, B, and Index
• Encoder power provided = 5VDC @ 40mA
• Includes internal pull-up resistors for the A/B/I encoder inputs
• Status lights on all digital inputs and supply voltages; 7 lights in total included
  • 5VDC from Talon SRX present = green LED
  • 3.3VDC from Talon SRX present = green LED
  • Encoder A input low = amber LED
  • Encoder B input low = amber LED
  • Encoder Index input low = amber LED (can also be used with a PWM-style absolute encoder; brightness indicates approximate shaft angle)
  • Motor Limit FWD input low = red LED
  • Motor Limit REV input low = red LED

Analog Inputs

• Analog power provided = 3.3VDC or 5VDC @ 20mA, selected by solder jumper SJ-2
• Very high impedance analog input that is buffered and scalable 0-3.3V or 0-5V by a solder jumper SJ-1
