An electrical module, a backplane for the electrical module, and a method of replacing a fuse for the electrical module. The electrical module includes a circuit board which has a power input port for inputting electric power to electrically drive an external device coupled to the electrical module. The electrical module also includes a fuse holder electrically coupled to the power input port and adapted to receive a fuse. A fuse detecting circuit is arranged on the circuit board and electrically coupled to the fuse via the fuse holder to detect a status of the fuse. An output port is arranged on the circuit board and coupled to the fuse detecting circuit to at least output detecting signals about the status of the fuse to a controller.

Electrical module and associated backplane

Embodiments of the present disclosure provide industrial control apparatus and monitoring methods for industrial control apparatus. The industrial control apparatus comprises: at least one input or output module, each input or output module comprising a fuse adapted to be coupled between a power supply and a user load, and a detection assembly coupled to the fuse and configured to send a detection signal after monitoring that the fuse is blown; and a processing device communicatively coupled to the detection assembly of each input or output module and configured to output information that the input or output module associated with the detection signal is blown. By the aspects of the present disclosure, it is advantageous for an operator to timely obtain information that the fuse is blown and to improve the efficiency of locating and replacing the fuse.

Industrial control apparatus and monitoring method for industrial control apparatus

A terminal block unit for an input/output device of a modular process control system includes two slot elements configured to receive two redundant signal conditioning units. The terminal block unit is configured to be housed in a pair of two adjacent slot elements of a module termination unit of an input/output device. The terminal block unit provides a parallel connection of the redundant signal conditioning units to a field device.
