8170+ 1/8 DIN Valve Motor Drive Controller

The 8170+ is a 1/8 DIN controller with continuous online open loop control of valve motor drives or electric actuators. This feature allows for accurate control without the need for slidewire feedback. This lowers the cost of the motor and wiring, without sacrificing control.

The 8170+ incorporates our advanced tuning algorithms, with selectable pre-tune and self-tuning for easier setup. The self-tune also reduces output activity to an absolute minimum without compromising control quality, thereby reducing wear and tear on mechanical components such as valves, contactors and relays. In test, these controls have cut down valve oscillation from 30 to 40 times a minute to just a few. Pre-tune plus self-tuning has also been shown to get on control up to 3 times faster.

Our Plug and Play Technology allows you the ability to easily add to the controller’s features including communication by simply installing additional plug-in boards. Inputs, Outputs, Alarms, and Communications are all field upgradeable! This allows you to only pay for the options that are required on todays applications.

The controller is also easy to setup, with an innovative configuration port for off line programming directly from a PC or through a simplified operator’s front panel. Access can also be limited by either a security code or by setpoint options
