The AFP2441 is a specialized high-speed counter hardware module engineered exclusively for the Panasonic FP2 and FP2SH programmable logic controller backplane platforms. The physical net weight of the hardware unit is approximately 110 grams, and it draws a continuous current of 450 mA or less from the 5V DC system backplane supply during operation.
Maximum pulse input frequency of 200 kHz per single channel
For its electrical input interface, the module incorporates signal pathways isolated via built-in photocoupler hardware, featuring a nominal input impedance of 3.2 kΩ. It is built to receive a standard rated voltage of 24V DC with a rated input current of approximately 7.5 mA, maintaining normal signal capture within a broad DC power fluctuation range from 20.4V DC to 26.4V DC. The insulation barrier between the external wiring terminals and the frame withstands a dielectric breakdown voltage of 500V AC for 1 minute, with an insulation resistance of 100 MΩ or more when verified using a 500V DC megger testing instrument.This hardware supports NPN-type (sinking) input, featuring four 200 kHz channels and eight interrupt inputs. It utilizes FROM non-volatile memory for data retention and is designed to resist environmental factors like vibration and shock, complying with RoHS.

Plastics Processing
Monitors pulse feedback from inverter motors in profile extrusion cutting lines to ensure fixed-length cutting precision.
When utilizing the Panasonic AFP2441, the critical priority is evaluating the system's 5V internal current consumption. This specific module draws a substantial current of up to 450 mA at 5VDC, meaning the cumulative power demand of all backplane units must remain strictly within the maximum threshold of the primary power supply to prevent system instability.
Additionally, when wiring external encoders for its 200k count/s high-speed tracking channels, proper input filter timing should be configured, and all MIL connector adjustments must be completed while the system is powered off to safeguard the input circuitry from electrical damage.

Technical notes
Technical notes
The Panasonic AFP2441 is a 4-channel high-speed counter module developed for FP2/FP2SH PLCs, supporting a 200 kHz maximum frequency and 8 integrated NPN interrupt inputs. Utilizing photocoupler isolation for 24V DC pulse signals and storing parameters locally within onboard flash memory, it independently executes hardware-level high-speed comparison outputs and multi-axis motion synchronization without draining main processor and network bus bandwidth.
How many independent counter channels does the AFP2441 contain?
This hardware unit contains 4 independent physical counting channels internally.
How should products like the AFP2441 be used?
To use it, physically plug the unit into a slot on the main rack or expansion backplane of an FP2/FP2SH series PLC, connect rotary encoders or proximity switches via the front terminal block wiring, and read the counting data through the PLC ladder program.
What type of transistor output does the AFP2441 feature?
It is equipped with an NPN sink-type transistor output interface, which is used to establish direct physical hardware interlocks with external actuators or internal logic.
Which counting modes are supported by the AFP2441?
It supports 2-phase input, add/subtract counting input, and 1-phase direction-independent counting input modes at the hardware level.
Can the AFP2441 be physically hot-swapped without shutting off the PLC system power?
No. The external 24VDC and AC power supplies to the PLC main rack and backplane must be completely isolated before physically inserting or removing this module.
