Motor Control Details

The ABB Bailey IECAB11 Motor Control Unit requires a separate 24 VDC or 120 VAC control supply. You can connect the unit directly to the INFI 90 I/O bus for remote commands. The overload relays trip automatically when motor current exceeds set limits. Moreover, the auxiliary contacts provide run status and fault signals to the controller. This design allows automatic motor sequencing without operator intervention.

Mechanical Integration and Mounting

You must mount the ABB Bailey IECAB11 Motor Control Unit onto a standard DIN rail inside the motor control center. After positioning, secure the unit using the integrated rail clip at the rear. The unit measures exactly 28.0 centimeters in length and 12.0 centimeters in width. Its total weight reaches approximately 1.35 kilograms for stable rail mounting. Furthermore, the front panel includes a green LED for local run status indication.

Environmental and Storage Guidelines

You should store this ABB Bailey IECAB11 Motor Control Unit in a clean dry location away from vibration. The unit operates reliably between -10°C and +55°C ambient temperature. Likewise, keep the unit away from conductive dust or corrosive gases. Because the unit contains no battery, you can store it for years without performance degradation.
