HPO-6704 | Accessory: Output Module, HOA, 4-20mA
OVERVIEW | Accessory: Output Module, HOA, 4-20mA
For enhanced controller output options (such as manual control, using large relays, or for devices that cannot be powered directly from a standard output), install a relevant HPO-6700 series output override board (in supporting controller models only).
The HPO-6701/6703/6705 boards are designed to convert a binary/digital output to a relay contact or triac output and to provide “Hand-Off-Auto” control and feedback functions. These boards provide:
- Optical isolation between the controller and the load, plus zero-cross switching (HPO-6701 triac).
- Mechanical isolation between the controller and the load (HPO-6703/6705 relays).
The HPO-6702 enhances the analog voltage output with a “Hand-Off-Auto” control while providing an adjustable potentiometer for override settings while in the “Hand” position.
The HPO-6704 converts a standard analog voltage output to a 4–20 mA output with “Hand-Off-Auto” control while providing an adjustable potentiometer for override settings while in the “Hand” position. (Since the HPO-6704 supplies the power, it will not work with a 4–20 mA device that also supplies its own power.)
Each output board (except HPO-6703-1) has an accessible three-position slide switch for selecting the “Hand-Off-Auto” functions. While in the “Hand” position, the output is manually energized, and the controller is provided with a feedback signal to indicate the output has been overridden. While in the “Off” position, the output is manually de-energized, and the controller is provided with a feedback signal to indicate the output has been overridden. While in the “Auto” position, the output is under the command of the controller.
Each output board also has a red LED indicator that is On when that board’s output is turned On (either manually or automatically).
