Return to TOC Curtis Model 1220E – August 2022
I/O Ground (pins J1-2, J3-10, J3-14)
e Command and Feedback Pot Low pins are connected to I/O GND. ey are not protected against
short circuits to B+.
Fault Output (pin J3-1)
e Fault Output has independent supervision via the MCU, and can be used for power supply of
the traction main contactor coil. is output is protected against short circuit to B-.
Max output current 3A
Max voltage drop (to KSI) at 3 A 1 V
Max short circuit current at max voltage 7A
Programmer Connections
e Curtis programmer plugs into the 4-pin connector, J1.
Rx (Pin J1-1)
is is the data input connection to/from the programmer.
Max LOW threshold voltage: 1.50 V
Min HIGH threshold voltage: 3.50 V
Tx (Pin J1-3)
is is the data input connection to/from the programmer.
Logic Level O:
Min output sink current 2.8 mA
Max output voltage at current < 2.8 mA 0.6 V
Logic Level 1:
Min output source current 0.4 mA
Min output voltage at current < 0.4 mA 3.5 V
CAN Communications
Separate CAN ports provide complete communications and programming capability for all user
available controller information.
Note: Wiring the CAN TERM H and CAN L together provides a local CAN termination of 120 Ω,
0.25 W. CAN TERM H and CAN L should never be connected to any external wiring. Typically the
wiring of the CAN bus nodes is a daisy chain topology with 120 Ω CAN terminating resistors at each
end. If the vehicle wiring is done such that the 1220E is the last node in the chain, CAN TERM H
and CAN L pins should be connected together.
CAN H (Pin J3-8), CAN L (Pin J3-12)
Protected voltage: –5V to +58V
Max baud rate: 1Mbps
