加-减计数器

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.

Operating modes:

• Up counter with enable input
• Up/Down Counter
• Frequency counter
• Peak-time counter

Indicators:

• Green LED (Up/Down + CLK + DO status)
• Red LED (Up/Down + CLK error status)

Field and system levels are electrically isolated.

The device is ideal for operation in extreme environments thanks to:

• An extended temperature range
• Greater immunity to impulse voltages and electromagnetic interference
• Higher vibration and shock resistance
