The Omron H8PS-16BFP, also cataloged as the H8PS Cam Positioner, operates as a dedicated hardware component for rotary position decoding and high-speed angle comparison switching within high-density automated machinery.

Model Nomenclature Breakdown

• H8PS: Base series designation for electronic rotary cam controllers.
• 16: Specifies 16 discrete transistor output channels.
• B: Denotes panel-mount or DIN-rail compatible housing frame with LCD backlight display.
• F: Indicates front-panel flange surface/DIN-rail dual mounting structure.
• P: Identifies PNP transistor sourcing output configuration.

Technical Performance Matrix

Industrial Controller Bus Integration and Firmware Memory Protection

Integrated decoding logic processes high-frequency absolute encoder inputs to evaluate shaft angles against active cam profiles. High backplane bus communication velocity Licences sustain rapid cycle execution across networked PLC platforms, while strict firmware flash compatibility guarantees persistent EEPROM memory retention of set points without battery backup.

Field Mounting and Wiring Protocols

Mounting Structure Selection

For panel door installation, prepare a standard 92 x 92 mm panel cutout and secure the unit using side locking clips. For control cabinet interior mounting, snap the base track onto a standard 35 mm DIN rail.

Encoder Phase Selection

Set the onboard DIP switch to select forward (CW) or reverse (CCW) signal decoding to align controller logic with physical machine shaft rotation without altering cable wiring.

Power and PNP Output Termination

Connect 20.4-26.4 VAC operating power to the main power terminals. Wire the 16 PNP sourcing transistor outputs directly to sourcing PLC inputs or relay loads, bonding the encoder shield drain wire to the Functional Ground (FG) lug.

Technical FAQ

• How is the encoder rotation direction reversed at the controller level?

  An internal DIP switch toggles phase evaluation between Clockwise (CW) and Counter-Clockwise (CCW) without physically swapping signal wires.

• How are the 16 transistor outputs electrically configured?

  Outputs are PNP open-emitter transistors that source DC voltage directly to connected loads or sourcing PLC input modules.

• What preserves cam switch programs during complete power failure?

  Internal non-volatile EEPROM stores all 16-channel ON/OFF angle settings indefinitely without relying on a backup battery.

• What happens if the absolute encoder interface cable is severed?

  The internal logic detects signal loss, immediately de-energizes all 16 PNP outputs, and generates an encoder alarm status on the LCD display.

• Can the positioner unit be installed on a standard DIN rail?

  The H8PS-16BFP housing features dual mounting capability for both 1/4 DIN panel cutout mounting and standard 35 mm DIN rail installation.

• Is hot-swapping the absolute encoder wiring permitted during operation?

  Disconnecting or reconnecting the encoder while AC power is applied risks damaging internal logic circuits and causing false output switching.

• What grounding procedure prevents signal noise on the encoder cable?

  Connect the shield wire of the absolute encoder cable directly to the Functional Ground (FG) terminal on the positioner to prevent ground loop interference.

• What is the allowable operating supply voltage range for the AC power terminals?

  The unit operates reliably within an AC power supply range of 20.4 to 26.4 V; voltages outside this window may cause controller lockup or component damage.
