West P8170 Temperature Controller
West Instruments is pleased to announce the launch of its new line of 'Plus Series' valve motordrive (VMD) discrete controllers, the 6170+ (1/16DIN), 8170+ (1/8DIN) and 4170+ (1/4DIN). They supersede the N series and have added new features including:
- Remote Setpoint Option
- Modbus Communications Option
- Transmitter Power Supply Option
- Open Loop Valve Control with or without Position Indication
They also offer an improved Plus Series interface and greater field flexibility, as well as incorporating the proven reliability of existing Plus models.
The controllers are used for continuous online open loop control of valve motor drives or electric actuators. This allows for accurate control without the need for side-wire feedback. This lowers the cost of the motor and wiring, without sacrificing control.
The controllers incorporate advanced tuning algorithms, with selectable pretune and self-tuning for easier setup. The self-tune also reduces output activity to an absolut minimum without compromising control quality, therby reducing wear and tear on echanical components such as valves, contractors 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.
Plug and play technology allows you the ability to easily add to the controller's features by simply installing additional plug-in-boards. Inputs, Ouputs, Alarms and Communications are all field upgradeable! This allows you to only pay for the options you need.
The controllers are alos easy to set up - either via PC configuration software or via the front buttons.
