The utility model belongs to the technical field of control loop testing, and discloses a control loop additional test complete device, which is characterized in that an
engineering machine is linearly connected with a programmable power pack and an on-off module through an RS232, is linearly connected with a digital IO card and a temperature and
humidity sensor through a
USB, and is linearly connected with an NI acquisition card and a first control
relay through the RS232; the NI acquisition card is linearly connected with the first
voltage sensor group and the first
current sensor group; the on-off module and the short-time power supply are connected with the first
voltage sensor group and the first
current sensor group; the digital IO card is linearly connected with the power supply module which is linearly connected with the second control
relay, the second
voltage sensor group and the second
current sensor group. The
system interface is friendly, and testing is carried out strictly according to the
usability principle. In order to avoid repeated operation of a user, the
system is embedded with an intelligent memory function, such as automatic configuration saving. And the same information cannot be input at multiple places or multiple times in the
system by the user, so that the uniqueness of the entrance is ensured.
