IO modules
The Voltmasters IO modules give the EMS extra inputs and outputs: the Volt DIO for digital signals and relays, the Volt AIO for analog 4-20 mA signals.
With an IO module the EMS reads signals and switches circuits that do not communicate themselves: a contact, a relay or a 4-20 mA current loop. The controller talks to the module over the network. Voltmasters has two IO modules:
| Module | Signals | What it does |
|---|---|---|
| Volt DIO | 6 digital inputs and 6 relay outputs | Switches relays and reads the position of contacts. |
| Volt AIO | 6 analog inputs and 2 analog outputs (4-20 mA), 2 digital inputs and 2 digital outputs | Reads and drives analog current signals. |
The controller talks to both modules over the network. The modules sit in the cabinet, next to what they drive.
Applications
| Application | Module |
|---|---|
| Switching a controllable load on and off, such as a heating element or a pump | Volt DIO |
| Executing a hardware emergency stop when the grid operator asks for it | Volt DIO |
| Grid operator watchdogs and signals, as with ORES | Volt DIO |
| The switches, the protection relay and the generator start of a microgrid | Volt DIO |
| Analog telecontrol of a Fluvius telecontrol cabinet version 4 | Volt AIO |
