MA4-2

The MA4-2 is a MICRO-AMP® plug-in one-shot Logic Module with adjustable pulse length. It is designed as a way to easily add one-shot timing to a MICRO-AMP system which uses an MA3 or MA3-4 amplifier. It may also be used to add one-shot timer to any current sinking DC device or to a system which offers a contact closure output. A low-going logic INPUT signal at pin #7 of the module activates an one-shot output at both pins #5 and #6, unless a low-going logic INHIBIT signal is present at pin #8 when the input occurs. Both NORMALLY OPEN (pin #6) and NORMALLY CLOSED (pin #5) outputs are available. Both are NPN open-collector (current sinking) transistors, each capable of switching up to 150mA.

• 0.001 to 0.1s Standard and 0.01 to 1s and 1 to 15s programmable ranges
• Single-turn timing potentiometer allows adjustment of pulse duration within the selected range
• Red LED indicator
• Totally encapsulated plug-in package with molded VALOX® housing with gold-flashed connection pins
• Two open-collector NPN transistors with complementary outputs
• 0 to 70°C (32 to 158°F) Operating temperature
