GE Fanuc IC660BBR100 Genius Normally-Closed Relay Output Block
Sixteen normally-closed relay outputs arranged in four isolated groups.
01Model Profile
IC660BBR100 provides sixteen normally-closed relay outputs in four independent groups of four. Each group can be powered from a separate AC or DC field source.
The relay contacts can switch control and indication loads operating from 5 to 250 VAC or 5 to 220 VDC, within the stated 60 W or 125 VA circuit limit. Group-to-group isolation is 1500 V.
Power-up defaults, hold-last-state behavior, CPU redundancy selection and Bus Switching Module control are configurable. Circuit LEDs indicate commanded coil state while block LEDs show unit and communication status.

Installation check
Circuit LEDs represent the commanded coil state, not field load current.
05FAQ
How does IC660BBR100 implement its Relay Grouping function?
Four outputs form each independently powered group.
Why must Load Switching Boundary be reviewed for IC660BBR100?
Check voltage and VA/W limits for every connected load.
Which Relay output grouping arrangement applies to IC660BBR100?
Four isolated relay groups; every group may use its own AC or DC field source.
Which Outputs and Contact state values define the Relay output grouping configuration IC660BBR100?
Outputs: 16 relay outputs; Contact state: Normally closed.
Before commissioning IC660BBR100, which Relay Grouping check matters most?
Separate group sources allow different field circuits within one block.
Which identity boundary is documented for IC660BBR100 when reviewing Relay Grouping?
