Expert Review

“The KL1512 is a reliable counter for basic counting tasks. Its 1 kHz frequency handles most flow meters and event counters. The 16-bit depth is sufficient for many industrial applications. Easy configuration via Bus Coupler saves time.”

Manager’s Insight

“This terminal is cost-effective and compact. It reduces wiring effort with pluggable connections. The UL and Ex approvals make it suitable for global and hazardous area installations. A solid choice for OEMs and system integrators.”

Applications & Suitable Devices

Flow meters – count pulses from turbine or paddle wheel meters.
Event counting – production batch counting, part counting.
Speed monitoring – measure RPM from proximity sensors.
Works with Beckhoff Bus Couplers (BK series) and controllers.

No. Counter depth is 16 bits (0 to 65535).
Is it Ex-approved for hazardous areas?
Yes. The terminal carries Ex approval (ATEX).
What is the input filter time?
0.2 ms – filters short noise pulses.
