3.3.3.2 4~20mA (Current Source)
This signal shows when various recorded information of current output is transmitted
through electrical wiring. It is varied according to the product status.
ㆍ Non-isolation output, Common 24V-_IN (-Power)
ㆍ Max. Terminating Resistance : 500Ω
- Types of Signal
ㆍ 0mA (+0.5mA) : Connection Fault
ㆍ 2mA (±0.5mA) : Self-Diagnosis test Fault
ㆍ 4mA (±0.5mA) : Normal
ㆍ 8mA (±0.5mA) : IR Detection only
ㆍ 12mA (±0.5mA) : UV Detection only
ㆍ 16mA (±0.5mA) : UV and IR Detection (Warning)
ㆍ 20mA (±0.5mA) : Fire Detection
- Signal of electrical wiring (3 Lines-Sourcing)
