Chain control boards come equipped with two distinct power outputs, each designed for specific components in your system. Understanding their specifications ensures proper operation and safe integration of devices.

Output 1 & 2: Flashing Light and 24Vac Power

• Purpose: These outputs are primarily used to power flashing lights.
• Specifications:
  • Voltage: 24Vac
  • Maximum Power: 25W
  • Maximum Current Draw: 1A (Calculated as 25W24V=1A\frac{25W}{24V} = 1A24V25W=1A)

Ensure that any connected device does not exceed these limits to maintain system reliability.

Output 3 & 4: 24Vcc for Photocells

• Purpose: Outputs 3 and 4 are used mainly for powering photocells.
• Specifications:
  • Voltage: 24Vcc
  • Maximum Current Draw: 200mA (or 0.2A)

Photocell Power Consumption

Photocells draw different amounts of current depending on their operational state:

• Inactive State (Beam Not Interrupted):
  • Current Draw: 10mA
• Active State (Beam Interrupted):
  • Current Draw: 30mA

These values are well within the 200mA limit of Outputs 3 & 4, ensuring safe operation when multiple photocells are used.
