Abstract: A monitor can be installed in the terminal block having a monitor access opening. The installed monitor allows for current measurement without having to disconnect a wire from the terminal block. Similar monitors can measure voltage, detect ground loops, and provide continuous readings of circuit parameters. Embodiments can positively hold probe tips, transmit data over wires, or transmit data wirelessly. Make-before-break monitors allow parameters to be measured without ever breaking the monitored circuit. Break-before-make monitors allow the monitored circuit to be interrupted and then reconnected with a monitor in place.

Abstract: A process interface device for a process facility running a physical process includes a multi-loop current junction box including an analog front end (AFE) having a signal path including an input node, an output node, and an internal current sensor for each current loop. Respective input nodes receive analog current sensing signals (sensing signals) originating from each field devices within the process facility. An analog to digital converter (ADC) has inputs coupled across an output of the internal current sensor device. A wireless single hop device (WSH device) includes a processor and a wireless transmitter, wherein an input of the WSH device is coupled by a communications bus to receive respective outputs generated by the ADC being digitized versions of sensed ones of the sensing signals (sensed sensing signals). The WSH device is for wirelessly multiplex transmitting the sensed sensing signals for remote monitoring of the current loops.
