8280-604 723和723PLUS数字控制器

Product Description

Part 8280-604 is a digital controller in the 723PLUS series. This unit has many features that are standard for controllers in this Woodward series, including some configurations to make the 8280-604 suitable for a range of applications. The 8280-604 is CE Compliant and CSA Certified. Additional compliance info can be found in 723PLUS hardware manual 02877.

Woodward model 8280-604 has multiple communication ports which are user configurable. RS-232, RS-422, or RS-485 communications are supported through two separate serial interfaces. Two LON channels can be used to connect LinkNet nodes to expand the control’s I/O ports. Alternatively, the LON channels can be used for Woodward LONTalk.

This 723PLUS control is a low-voltage model with an external power supply. The power supply of the low voltage 723PLUS control models is rated for 18–40 Vdc (24 or 32 Vdc nominal), requiring 40 W. High voltage 723PLUS control models are also available.

One or two proximity switches or magnetic pickups (MPUs) can be used with the 8280-604. There is a slightly different frequency range for each option. MPUs can be used for a speed input frequency range of 400 Hz to 15 kHz. Proximity switches have a 30 Hz to 15 kHz range. 30 Hz is the minimum frequency for steady-state speed control.

One excellent feature included with this model is its ability to be configured when it comes to the various time groups. The 8280-604 model can be configured to time groups of ten to eighty milliseconds. Information can be found in several bulletins from Woodward, which give general information on how this model will function alongside the 723 and 723PLUS models.
