Description

Vigor PLC Analog Module VB-4DA

• Extended Product Type : VB- series

• Product ID: VB-4DA

• Prosoft Type Designation : VB- series

Features and Benefits

● Provides 4 channels analog input, each one 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 OFFSET and GAIN of each input 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 : 0.8 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, 30 mA (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 an Expansion Unit or VB-PWR:
[ (The amount of Expansion Modules) + (The amount of Special Modules) X 2 ] ≤ 12
● 24 V DC (+20% / -15%), 120 mA Max. (for analog signal output)
Supplied from external power supply or 24 V DC output of PLC.
