PH2
Photo Sensor
Overview
PH-2 is an indoor-type photo sensor developed for lighting control applications.
This photo sensor detects illuminance through a built-in photocell, with a sensing range of 0–2,000 LUX.
When the illuminance sensitivity setting button is set to “0”, the sensor can be connected to the ELC system for integrated illuminance-based control.
When used with third-party systems, selecting sensitivity levels 1 to 15 provides dry contact signals while simultaneously allowing illuminance sensitivity range selection and application.
Feature
  • Flexible installation method: ceiling-mounted type for on-site ceiling installation.
  • Integrated power and communication sensor: can be connected directly to the system communication line without a separate communication sensor module, and can also provide dry contact signals when connected to third-party systems.
  • Intelligent illuminance control: illuminance sensing range can be adjusted within 16 selectable levels between 0 and 2,000 lux.
  • Independent stand-alone operation: programs can be downloaded into the sensor, enabling independent relay-based control without a separate controller.
Operation
Application
  • Direct connection to the ELC communication line for illuminance measurement.
  • Real-time data integration with upper-level software.
  • Precise illuminance monitoring with 4096-step sensing resolution.
  • Relay control linked to illuminance settings through communication-based downloading.
  • Integrated stand-alone sensor that does not require a separate sensor module and supports independent control through downloaded programs.
  • Illuminance sensitivity (16 levels) and sensor timer settings (16 levels) can be adjusted and configured, and related programs can also be set through communication.
  • Compatible with existing ELC-based installations and convenient for easy integration and maintenance.
  • Built-in AC220V 15A relay for direct on/off control in the field.
