Linear, rotary valve actuators incorporate DeviceNet

Addison, Tex .—Mini-Top Series valve actuators improve valve control via high-resolution positioning that employs a built-in feedback positioner and electronic limiter. Mini-Top needs less wiring than comparable actuators, thereby reducing I/O requirements on the PLC or other higher level control system, says the manufacturer.

Addison, Tex .—Mini-Top Series valve actuators improve valve control via high-resolution positioning that employs a built-in feedback positioner and electronic limiter. Mini-Top needs less wiring than comparable actuators, thereby reducing I/O requirements on the PLC or other higher level control system, says the manufacturer. A stepping motor assures long-life actuator operation in environments detrimental to a standard brush dc motor. DeviceNet communication simplifies installation, while precisely controlling and monitoring the position of valves and dampers. Each actuator forms a node on the network, with up to 64 devices allowable. Compared to analog-based instruments, these digital actuators supply added information useful to engineering and maintenance staffs—for example, actuator self-diagnostics, configuration parameters, total operating time, etc. www.m-system.com M-System Technology
