The NC400-6 is an advanced 6-digit counter that also performs batch and totaliser counting operations — well suited to simple product counts at the end of a conveyor, stopping a process on a counter target, or triggering an alarm on batch completion. It has 2 outputs with independent, configurable presets that can be triggered based on counting, batch, or totalisation values, each with independent timed triggering. Built-in 12V auxiliary power is available for sensors, and units can be supplied pre-programmed or enclosed and ready to use on request.
The counting inputs can be configured to connect dry-contact, voltage pulse, NPN, or PNP sensors, which may be powered by the internal power supply.
Counting mode can be configured as progressive, regressive, quadrature, sum, or subtraction. Several reset modes — automatic or manual — can be configured, with manual reset triggered by a digital input or the front panel key.

Frequently Asked Questions
Can I power an external sensor directly from the counter?
Yes — built-in 12V auxiliary power is available for connected sensors, so no separate power supply is needed.
What sensor types can I connect?
Dry-contact, voltage pulse, NPN, or PNP sensors are all supported on the counting inputs.
Can this reset automatically at the end of a batch?
Yes — several automatic or manual reset modes are configurable, with manual reset also available via a digital input or the front panel key.
Industry Applications
- Conveyor & Production Counting — simple product count display with batch and totaliser modes.
- Batch Completion Alarms — independent presets trigger on counting, batch, or totalisation targets.
- Process Interlocking — stops a process automatically once a counter target is reached.
