Abstract: The present invention provides a counter unit (10) that supports, in a plurality of output devices, both a case where there is no problem in a state in which common signal terminals or power supply terminals are connected by common wiring, and a case where it is preferable to connect the common signal terminals or the power supply terminals by circuits insulated from each other. The counter unit (10) is provided with a switching unit (15) that performs switching between a non-insulated circuit (16) that connects a plurality of common signal terminals (COMA, COMB, COMC) and/or a plurality of power supply terminals (IOV, IOG) by common wiring, and an insulated circuit (17) that connects the plurality of common signal terminals and/or the plurality of power supply terminals by circuits insulated from each other.

Abstract: A temperature control unit according to one or more embodiments may include an acquisition unit that is configured to acquire an operation amount from a controller, and an SSR control unit that is configured to perform time proportional output of an instruction to drive or stop a heater to SSR after reflecting the operation amount.

Abstract: A temperature control unit has an acquisition unit that acquires first information regarding driving and stopping of a heater and second information indicating whether or not to subject a time proportional output to an SSR to autonomous control and an SSR control unit that performs time proportional output of an instruction to drive or stop the heater, to the SSR.

Abstract: A signal processing circuit with high noise resistance is realized. The signal processing circuit includes: a first pre-stage circuit that includes a first input terminal; and a second pre-stage circuit that includes a second input terminal. A resistive element with one end connected to the first input terminal and a capacitative element with one electrode connected to the ground are provided in the first pre-stage circuit. The other end of the first resistive element and the other electrode of the first capacitative element are connected to each other. An output node of the first pre-stage circuit and an output node of the second pre-stage circuit are connected to a post-stage circuit.
