Vigor PLC Analog Module VB-3A

• Extended Product Type : VB- series

• Product ID: VB-3A

• Prosoft Type Designation : VB- series

Features and Benefits

● The VB-6A provides 4 channels analog input and 2 channels analog output, each I/O has12-bit
high precision resolution.
● The VB-3A provides 2 channels analog input and 1 channel analog output, each I/O has12-bit
high precision resolution.
● The voltage (-10 V ~ +10 V) or current (-20 mA ~ +20 mA) input can be specified for each
channel independently.
● The voltage ( 0 V ~ +10 V ) or current ( +4 mA ~ +20 mA ) output can be specified for each
channel independently.
● The OFFSET and GAIN of each input / output channel can adjust independently.
● Equipped with a 10 V DC accurately standard voltage output (60 mA Max.), offers reference
power source for the linear potentiometer.
● Photocoupler isolation between input analog signals and digital PLC circuits. Inner DC to DC
isolated converter supplies the clean power.

Specification

• Overall Accuracy : ± 1% (full scale)
• Conversion Speed : 0.5 ms × 1 ~ 4 activated point(s)
• Isolation : Photocoupler isolation between analog and digital circuits.DC/DC converter isolates of power from its power source.No isolation between analog channels.

Power Requirement

● 5 V DC (for internal control)
Supplied from PLC Main Unit (or Expansion Unit / VB-PWR) via its extension cable.
○ From a Main Unit:
[ (The amount of Expansion Modules) + (The amount of Special Modules) X 2 ] ≤ 4
○ From a Expansion Unit or VB-PWR:
[ (The amount of Expansion Modules) + (The amount of Special Modules) X 2 ] ≤ 12
● 24 V DC (±20%), VB-6A: 210 mA / VB-3A: 160 mA (Max.) (for analog signal output)
Supplied from external power supply or 24V DC output of PLC.
