IC660BBR100 GE Fanuc Output Block

GE Fanuc IC660BBR100 Normally Closed Relay Output Block

Technical Specifications & Key Features

• The IC660BBR100 offers 16 relay output circuits arranged in four groups of four.
• Each output group provides 1500V AC isolation from the other groups for enhanced safety and design flexibility.
• It controls a wide voltage range: 5 to 250 Volts AC or 5 to 220 Volts DC per output.
• As a normally closed block, the relay contacts conduct current when the module is de-energized.
• Each isolated group can be powered by a separate AC or DC source, allowing mixed voltage applications.
• The block draws only 87 milliamps at 115V AC for its internal control power.

Configuration & Application Use

• This block is ideal for driving indicator lamps, contactors, solenoids, and other relays.
• Configure output behavior for power-up, including holding the last state or using a default state.
• Set up CPU redundancy and bus switching module control via a handheld monitor.
• The factory-set block power can be configured for either 115V AC or 230V AC operation using terminal jumpers.

Frequently Asked Questions (FAQ)

• Q: What does "normally closed" mean for this output block?
  A: The IC660BBR100 contacts are closed (conducting) when the module is powered off. They open when the output is energized.
• Q: How many independent power groups do the outputs have?
  A: The 16 outputs are divided into 4 isolated groups of 4. Each group can use a different AC or DC voltage source.
• Q: What is the isolation rating between output groups?
  A: There is 1500V AC of electrical isolation between each group of four outputs.
• Q: What load voltages can this relay block control?
  A: It can switch loads ranging from 5-250V AC or 5-220V DC, making it highly versatile.
• Q: Is the block power fixed, or can it be configured?
  A: The block's internal control power can be set for either 115V AC or 230V AC using terminal jumpers.
