Units and display - Units: feet, inches, meters, yards; freely switchable. - Two-row, 6-digit counting with a red LED display. - Counts up to 999999 and supports positive and negative counting. - Dual relay control for simultaneous operation of two devices. Dual relay outputs - The digital length counter has two relay outputs to control two devices at once. - Independently drive alarms, motors, cutters, inverters, or solenoid valves. - With these two relays, you can connect the entire line to control other devices for fully automatic operation. Memory function - Maintains the last value after a power outage; resumes when power is restored. - Useful for recording fabric lengths in fabric mills, textile factories, and garment factories. - Also suitable for use in printing facilities. Alarms and settings - Can be connected to an alarm and supports preset alarms. - When the preset value is reached, the alarm triggers automatically and can be set to auto reset for convenient operation. - Note: the alarm device must be purchased separately. Use scenarios - Textile production lines: measure fabric length during weaving, cutting, or handling, with automatic relay-driven actions. - Printing and finishing facilities: track material length for substrates and coordinate workflows. - Automated line control: integrate the dual relays to manage alarms, motors, cutters, inverters, or valves for fully automatic operation.
