Terminal block unit, and monitoring system using the same

Abstract

[Problem] To provide a terminal block unit that reduces wiring work and wiring mistakes, lessens installation work, and is capable of flexibly providing necessary functions, and that furthermore has excellent expansion capabilities and can flexibly provide necessary functions even if the number of contacts increases. [Solution] A terminal block unit 10 that is the minimum unit for constructing a measurement system using a sensor or a control system for a monitoring and/or control device using the measurement system, the terminal block unit 10 being used interposed between a sensor or control device connected downstream of the terminal block unit 10 and host devices 28, 30 connected upstream of the terminal block unit 10, the terminal block unit 10 including a plurality of contact terminals 12 and being electrically connected to the sensor or control device through the contact terminals 12, and the terminal block unit 10 being configured such that it is possible to provide direct connection between terminal block units 10 and between the terminal block unit 10 and the host devices 28, 30 via a common bus.
