Specifications
First-order Lag Transducers [Non-insulated]
These transducers apply a time constant to the DC input signal and delay the response
speed.
The time constant can be set to any value between 1 and 60 seconds.
Applications
Averaging highly fluctuating signals
Prevents control system oscillation

The time constant (τ) refers to the time required for an output value to
reach 63% of a fixed input value when the input is applied continuously.
