HARDWARE AND WIRING
Digital Inputs
These inputs are in low state by providing a connection to battery ground and placed in high
state by providing an open circuit.
Digital Input Requirements:
High State:
V
in
≥
2/3 Battery (+)
Low State:
V
in
≤
1/3 Battery (+)
Isink:
Capable of sinking 5–20 mA
NOTE:
Use switches that will not oxidize with the passage of time and environmental factors
due to the low source current.
Digital Outputs
There are 15 digital outputs located on the CPC.
High Power Outputs
DO_HP_FLEX-01 – 4/9
DO_HP_FLEX_02 – 3/17
DO_HP_HS_01 — 3/7
DO_HP_HS_02 — 3/8
DO_HP_HS_04 — 4/10
DO_HP_LS_01 — 3/9
DO_HP_LS_02 — 4/7
Low-side High Power Output Characteristics:
Resistance:
12 V - vehicle power: R > 8 ohms
Inductivity:
≤
800 mH (if valve or relay load)
Capacity:
≤
10 nF
Isink:
Capable of sinking less than or equal to 2.0 A
3-32
