These versatile dual input
instruments will perform a variety of counting and timing functions within the
hazardous area. Both inputs will operate for two wire proximity detectors,
switch contacts, magnetic pick-offs or voltage pulses. All models can be
supplied calibrated to customers requirements or easily programmed on-site using
a simple menu. These functions can be further extended by the addition of
optional alarm outputs to switch any certified intrinsically safe load, such as
a solenoid valve or sounder. In the event of power failure, an internal battery
will maintain all instrument functions for 24 hours. Field or Panel-Mounting
