<p>This counter records binary pulse signals with NAMUR-compliant levels and transmits the counter state to the fieldbus system. The counting direction in “up/down counter” mode can be set using the U/D input. A control byte sets or resets the counter and digital output (DO). Additionally, a limit value can be set at which the DO output is activated when this value is exceeded. The output is short-circuit-proof.</p><p>Operating modes:</p><ul><li>Up counter with enable input</li><li>Up/Down Counter with U/D input</li><li>Frequency counter with enable input</li><li>Peak-time counter</li></ul><br/><p>Indicators:</p><ul><li>Green LED (status U/D (Gate) + status CLOCK + status DO)</li><li>Red LED (error U/D (Gate) + error CLOCK)</li></ul><br/><p>Field and system levels are electrically isolated.</p>
