Bus Networks
K-TORK actuators can be supplied to interface with a variety of industry-standard 2-wire or 4-wire Bus Network protocols that transfer both monitoring & control AND power to each actuator. These standard communication networks and intelligent valve controls will reduce installation costs (wiring & conduit) and start-up expense, reduce I/O costs, reduce panel space and MCC requirements, reduce ongoing power consumption and enable valve and instrument diagnosis.
K-TORK Conventional System VS. Bus Network
- Conventional actuator wiring networks attach each of the inputs and outputs (I/O) to a central location, resulting in mulitple wire runs (up to eight wires per actuator). Large expenditures are needed for cabling, conduit, installation and I/O points. Add high-voltage supply power, circuit breakers and MCC's to the equation with electric actuators.
- K-TORK Bus Network-controlled actuators will interconnect with other instruments, sensors and field devices to form Water and Wastewater Plant Intranets. There are a variety of ways to wire a Bus Network that will provide redundancy and reliability, while significantly reducing the project budget for traditional wiring and conduit. Bus Networks are designed for use with both discrete (O/C) and analog (Modulating) valve actuators and will interface with existing SCADA, PC, DCS, and PLC systems. Additionally, the low voltage 24 VDC system comsumes very little power and is easily supported with a UPS back-up power supply to maintain operations during a power outage.
