16 channel thermocouple data logger
TS-5740 Series Four–circuit Digital Display Controller
TS-5740 four–circuit digital display controller adopts surface mounting technology and automatic placement machine production with strong disturbance resistance capacity. The controller supports input of several kinds of signals and can be used with a variety of sensors and transmitters to realize measurement display of temperature, pressure, liquid level, speed, force and other physical quantity. It can display measurement signals at four channels simultaneously and be equipped with 8–channel separate alarm output or 4–channel separate alarm output, RS485/232 communication and other output functions, thus suitable for systems to carry out inspection of synchronous measurement of multi–points.

Notes:
1. For model selection, selection of functions has to depend on the wiring diagram. As a controller of a small size has fewer terminal connectors, comprehensive functions cannot be achieved and sometimes, only one function can be selected for a set of terminal connectors.
Notes:
1. Although the same set of terminal connectors in the diagram is marked with different functions, only one function can be selected. When RS485 and RS232 are available for a set of terminal connectors, only one of them can be selected.
2. The connection terminal of unified transmitting output is on the number one output terminal.
