TERMINOLOGY

• Deadband
Linear resolution

• Restart Limiting Timer
This function prevents the output stem operates frequently when the input signal is unstable.
To prevent the output stem operates frequently, it does not operate at the moment the input signal changes, but after a set period of time.

• Protective function
If the output stem is locked, the control circuit automatically stops.
It provides protection both electrically and mechanically.
To restart, turn off the power voltage and then turn on it to reset the electrical circuit.
Alternatively, you can leave the power voltage as is and input a signal value opposite to the one at the time of stoppage to automatically release it.

• Resolution
The ratio that the stem of the unit rotates according to input signal.
E.g. Resolution is 1/200 for the specification that input signal is 4 to 20 mA, output stem 90°, direct or reverse action. As the span of input signal is 16 mA (20 - 4 = 16 mA), when input signal is changed by 0.08 mA step (16 mA / 200 = 0.08 mA), the output stem rotates 0.45° (90° / 200 = 0.45°).
(Even for output stem 45°setting, resolution is 1/200 = 0.45°step)
It is not true that input signal = output signal.
(Not input signal 4.00 mA DC = output signal 4.00 mA DC, there is difference around 0.04 mA DC.)

• Linear Characteristics
The output stem reciprocates i.e. opens and closes according to the input signal. In the case of DM05R, the difference between the theoretical value and the actual distance that the output stem actually moved is expressed in percentage.
