The NEXSYS Pulse/Timer (PT1) is a Series C (8 pin) dual-channel, pulse generator (one-shot) that provides stable retriggerable/resettable operation for timed pulse output applications. The independent channels can also be wired in series to provide a propagation delay for a custom, time-delayed one-shot.
28V: Operating voltage (nom.), 4 mA current draw (max.).
GND: Continuous Ground required.
TR1, TR2: Detects a rising or falling edge signal level signal transition which functions as the control interface trigger to drive timed outputs.
RST1, RST2: Immediate termination (reset) of the pulsed output.
Q1, Q2: Independent outputs are one-shot drivers and are available with two output options. The defined timing options for the output pulse range from 125 ms to 20 seconds. The output load capacity is 2.0 A (Resistive), per channel.
Output = Ground – Normally High Impedance output becomes Ground for a specified time interval (pulse) when the input is triggered by the specified signal level transition.
Output = High Impedance – Normally grounded output becomes High Impedance for a specified time interval (pulse) when the input is triggered by the specified signal level transition.
To help system designers understand the potential of NEXSYS Component Technology, we have assembled a collection of Application Notes. The links below show example applications that utilize the Pulse/Timer component.
