FR1000
Brand: Wilkerson CorporationThe FR1000 monitors a DC input signal and provides one dpdt, 5 A alarm relay with an independently adjustable setpoint.
The setpoint has a set of red/green LEDs to indicate alarm status. The configuration of the alarm relay is user-settable as follows: High or Low - High selects alarm on an increasing signal.
Low selects alarm on a decreasing signal. Normal or Reverse - Normal position selects fail-safe operation (loss of power will result in alarm condition). The relay is energized in the non-alarm condition.
When the setpoint is exceeded, the relay de-energizes. Selecting the reverse position reverses this logic. Deadband or Latching - Deadband selects the independently adjustable deadband control.
Deadband for the alarm is adjustable from 0.1% to 100% of the input span. The deadband is symmetrical about the setpoint
