EtherCAT mvTBI (Terminal Board Intelligenti)

Ma.Vi.’s EtherCAT Slave Modular System, on Omega bar (Ω DIN EN50022), is today composed by 6 modules with configurable features and advanced functions, and it is continuously growing.

It was born from deep experience in plants requirements and offers high flexibility together with precision and modularity.

All input/output signals to/from modules have less than 10 µSec delay with respect to the EtherCAT packet sent by the Master. The Slave Modular System can be driven by any EtherCAT Master (TwinCAT, Ma.Vi. mvPMC eCAT, others).

The following modules are available:

Bus Coupler: mvTBI-EBC

  • 2 RJ45 bus connection with bypass function in case of power off
  • It interfaces and powers following modules through E-bus

Analog Input: mvTBI-E8AI

  • 8 independent analog input channels
  • Individually configurable on: ±10V, ±5V, 0-10V, 0-5V, 4-20mA, 0-20mA, ±10mA, ±20mA
  • 16-bit resolution for unipolar inputs

Analog Output: mvTBI-E4AO

  • 4 independent analog output channels
  • Individually configurable on: ±10V, ±5V, 0-10V, 0-5V, 4-20mA, 0-20mA, ±10mA, ±20mA
  • 16-bit resolution for unipolar outputs

Digital Input Output: mvTBI-E8DIO

  • 8 digital input channels (4 inputs 24V and 4 inputs 5V) and 8 digital output channels (4 outputs 24V and 4 outputs 5V)
  • Inputs at 5V can acquire Sink or TTL signals
  • Outputs at 5V can be configured as OpenCollector or Totem-Pole

Encoder/SSI Interface: mvTBI-E4ES

  • 4 independent acquisition channels individually configurable
  • Available input modes:
    • SSI or QIE (Quadrature Incremental Encoder) or TPE (Two Pulse Encoder)
    • 32 bit counter for quadrature encoder

Power Repeater: mvTBI-EPWE

  • Power Expansion for Field and E-Bus power
  • Field Max Current supplied: 10A
  • E-Bus Voltage supplied 2A. No configuration required
  • Transparent for EtherCAT Master

The strong point of slaves is total configurability: EtherCAT Master can set up each slave by mailbox.

Ma.Vi. has developed a mezzanine-card mvPMC-DSW on bus PCI, in which EtherCAT Master has been implemented; moreover the same board can produce also other communication deterministic protocols.
