GENERAL DESCRIPTION
The Large Display Timer and Cycle Counter is a versatile display that
functions as an Elapsed Timer or Preset Timer, with full-featured user
programmability. The meter includes a built-in Cycle Counter, relay output and
serial communications capability. The 6 digit displays are available in either
2.25" or 4" high red LED digits with adjustable display intensity. The 2.25" high
models are readable up to 130 feet. The 4" high models are readable up to 180
feet. Both versions are constructed of a NEMA 4X/IP65 enclosure in light
weight aluminum.
The Timer has two signal inputs and eight input operating modes. These
modes provide level active or edge triggered start/stop operation. The Timer
features 18 selectable timer ranges to cover a wide variety of timing applications.
The built-in Cycle Counter can be linked to timer operation to count timing
cycles, or function as a totally independent counter, accepting count speeds up
to 500 Hz. The display can be toggled either manually or automatically between
the Timer and Counter values.
In addition to the Timer/Counter inputs, a programmable User Input is
provided to perform a variety of meter functions. DIP switches are used to
configure the inputs for current sinking (active low) or current sourcing (active
high) operation.
The Setpoint Output can be assigned to the Timer or Counter value, and
configured to suit a variety of control and alarm requirements. The meter also
includes RS232 or RS485 serial communications.
CAUTION: Risk of Danger.
Read complete instructions prior to
installation and operation of the unit.
