Description

Vigor PLC Analog Module VB-2DA

• Extended Product Type : VB- series

• Product ID: VB-2DA

• Prosoft Type Designation : VB- series

Features and Benefits

● Provides 2 channels analog output, each one has12-bit high precision resolution.
● 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 output channel can adjust independently.
● Photocoupler isolation between output analog signals and digital PLC circuits. Inner DC to DCisolated converter supplies the clean power.

Specification

● The VB-2DA analog output module has two output channels. The output channels take in a digital value and output an equivalent analog (voltage or current) signal. This is called a D/Aconversion. The VB-2DA has maximum resolution of 12 bits.
● The selection of voltage or current based output is by user wiring. Analog ranges of 0 ~ 10 V DC , and/or 4 ~ 20 mA maybe selected independently for each channel.
● The VB-2DA analog output module is attached as an extension to the VB series Programmable Logical Controller (hereinafter referred to as “PLC”), and the VB-2DA is attached as an extension to the VB series PLC Main Unit. Each VB-2DA functions as a special module which transfers data with the PLC using the FROM / TO instructions, and would not occupy any input or output point. Up to 8 special modules can be connected to single VB2 series PLC; a single VB0 series PLC can connect with two special modules.

Power Requirement

● 5 V DC (for internal control)
Supplied from PLC Main Unit (or Expansion Unit) 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% / -15%), 100 mA Max. (for analog signal output)
Supplied from external power supply or 24 V DC output of PLC.
