Metso has developed simple plug-in network solutions that can be easily installed into a standard platform. On-board instructions clearly highlight the proper terminal connections as well as any protocol specific LEDs and switches.
The AS-Interface option is a single board plug-in solution and is available in both the small and the large enclosure. Because other available protocol options require both a network interface board and a protocol specific module, they are available only in the large enclosure.
Metso’s Valvcon I-Series network capable electric actuators provide on-board, push button CW and CCW control for manually driving the valve or damper. CW and CCW supervisory control is a significant user benefit for safe and fast set-up of the actuator. This eliminates handling live wires at set-up and reduces the chance of short circuit or incorrect wiring.
I-Series network capable actuators are available for 115 or 230VAC, only. Consult the factory for information on products available for other voltages.
Available network capable
electric actuators include:
AS-i (Actuator Sensor interface)
AS-i networks up to 31 field devices onto a single pair of wires that delivers both signal and bus power. AS-i control schemes interface very conveniently with most popular PLCs and DCS systems.
Modbus networks integrate up to 32 devices on a 4-wire network. Modbus interfaces conveniently with most popular DCS/PLCs.
DeviceNet integrates up to 63 devices on a 4-wire trunk network. DeviceNet interfaces conveniently with many popular DCS/PLCs.
Foundation Fieldbus is designed for use in the process industries. Foundation Fieldbus offers multi-drop capabilities (up to 32 devices per network), long trunk length and compatibility with intrinsically safe circuits. Foundation Fieldbus interfaces conveniently with many popular DCS/PLCs.
