Slice I/O—field power bus breaker
First Claim
1. An input/output (I/O) device for an automation control system, the I/O device comprising:
- a device housing containing control circuitry, the device housing being mountable to a support;
a control power input for receiving control power from a first adjacent I/O device when connected thereto, the control power input configured to supply control power to the control circuitry;
a control power output for outputting control power to a second associated adjacent I/O device;
a field power input for receiving field power from the first associated adjacent I/O device when connected thereto; and
a field power output for transmitting field power to the second associated I/O device;
wherein the field power input is selectively removable to prevent field power from being received by the I/O device from the first associated adjacent I/O device when connected thereto.

Abstract
An input/output (I/O) device for an automation control system includes a device housing containing control circuitry, the device housing being mountable to a support, a control power input for receiving control power from a first adjacent I/O device when connected thereto, the control power input configured to supply control power to the control circuitry, a control power output for outputting control power to a second associated adjacent I/O device, a field power input for receiving field power from the first associated adjacent I/O device when connected thereto, and a field power output for transmitting field power to the second associated I/O device. The field power input is selectively removable to prevent field power from being received by the I/O device from the first associated adjacent I/O device when connected thereto.

17. A method for selectively breaking field power distribution in an automation control system comprising:
-
providing at least on I/O device including a device housing mountable to a support, a control power input for receiving control power from a first adjacent associated I/O device, the control power input configured to supply control power to the control circuitry, a control power output for outputting control power to a second adjacent associated I/O device located opposite the first adjacent associated I/O device, a field power input for receiving field power from the first adjacent associated I/O device, and a field power output for transmitting field power to the second adjacent associated I/O device, wherein the field power input is selectively removable to prevent field power from being received by the I/O device from the first associated I/O device; and selectively removing the field power input from the I/O device to break field power distribution. - View Dependent Claims (18, 19, 20)
