IOcan is designed for permanent installation in automotive electrical systems and supports continuous connection to battery power.
11
12
## Supply Voltage
13
| Parameter	| Value |
14
|--|--|
15
|Operating voltage	| 9–16 V |
16
|Recommended nominal voltage	| 12 V automotive system |
17
18
The device should be powered directly from the vehicle battery through a fused supply.
19
20
Recommended fuse for vehicle installations: 30 A.
21
22
## Quiescent Current
23
24
IOcan is optimized for low standby power consumption.
25
26
| Mode	| Typical Current |
27
|--|--|
28
| Standby (KL30 only)	| < 0.5 mA |
29
| Active operation	| depends on connected loads |
30
31
The low standby current allows the device to remain permanently connected to battery power without significantly draining the vehicle battery.
32
33

42
43
This output allows IOcan to manage transmission power sequencing without external relays.
44
45
# Analog Input Measurement
46
47
IOcan analog inputs use resistor dividers to allow measurement of automotive voltage ranges while protecting the internal ADC.
48
49
Two divider configurations are used.

# Environmental Considerations
150
151
IOcan is designed for automotive environments.
152
153
Proper wiring and grounding practices are required to ensure reliable operation.
154
155
Recommended practices include:
156
157
* twisted pair wiring for CAN networks
158
* short CAN stubs
159
* proper termination at both ends of the bus
160
* properly crimped terminals
161
* soldering of the wires is not recommended
162
* Please remember that this device controls part of powertrain. Please take great care when wiring the device and the transmission.
