Advanced Integration
Specifically designed for ease of integration into automated systems, the MVC Plus Series offers communications and flexible I/O as standard.
Flexible I/O
- 120Vac control power input accepts long control circuit runs without the need for interposing relays.
- 8 programmable relay outputs for control flexibility without the need for external auxiliary relays or add-on cards.
- 2 programmable analog outputs (0 – 10Vdc or 4 – 20mA).
Communication Ready
Built-in comm ports
- RS-232 for one on one communications with a PC.
- RS-485 for multi-drop communications with Modbus RTU protocol as standard.
Multi-Drop
For on-line monitoring, control and programming, the MVC3 Control Center software uses the standard RS-485 port to communicate via Modbus RTU protocol. 
Multidrop compatible for communicating with multiple units in the field, global data such as operating currents, voltages, power factor, etc. can be displayed for each unit. Individual parameters for any selected unit are displayed in the lower right section of the screen, and are fully interactive in real time. Anything that can be done at the unit can be done via software. Communications options include DeviceNet, Fieldbus, Ethernet and several others.
One to One
Program and store soft starter setpoints with Windows based software, MVC3-Win. The software uses the RS-232 port to duplicate the operator interface on the screen and steps through the setup or storage of operating parameters.
