Function
This signal conditioner monitors an overspeed or underspeed
condition of a digital signal (NAMUR sensor/mechanical
contact) by comparing the input frequency to the user
programmed reference frequency.
An overspeed or underspeed condition is signaled via the
relay outputs. Line fault detection of the field circuit is indicated
by a red LED and relay. The startup override feature sets relay
outputs to default conditions programmed by the user for up to
1,000 seconds.
The unit is easily programmed by the use of a keypad located
on the front of the unit.
