2.4 Outputs
2.4.1 The output value varies with the PV value.
This functionality is only available for DVP02TUL-S/DVP02TKL-S series. When the PV varies, the corresponding output
will vary accordingly. Take 4~20mA as an example, and set the upper-limit to 1000, lower-limit to 0; when PV is 0, the
output will be 4mA and when PV is 1000, the output will be 20mA. When set it to a negative slope, and set the range to
0~1000; when the PV is 0, the output will be 20mA and when the PV is 1000, the output will be 4mA. As the linear graph
shown below, the analog output will vary according to the PV value.

2.4.2 Alarm Outputs
The alarm output is only available for DVP02TUN-S, DVP02TUR-S, DVP02TKN-S and DVP02TKR-S series, not for
DVP02TUL-S and DVP02TKL-S series. Alarm function is to set the input value to trigger the outputs to do corresponding
actions. There are 12 modes available for setups. The alarm output operations are shown below.
