214 Programmable Controllers
CJ1W-CTL41-E
4-Channel Counter Unit
• 4 independent counter channels for encoder or
pulse train inputs
• 4 Counter channels with 32-bit counter value
• Linear or circular counter mode selectable per chan-
nel.
• Max. input pulse frequency 100 kHz, or 400 k
counts/second in quadrature mode
• 32 comparison values (8 per channel) can be used
to trigger interrupts to the PLC CPU
• Counter channel settings can be reconfigured on-
the-fly
• Input level: line driver
(24 V inputs through dedicated terminal block).
• Easy connection (line driver or 24V) by using
XW2G-40G7-E screwless terminal block)
This Unit offers an economical way to acquire position information from up to four encoders, or to count fast pulse trains up to 100 kHz.
Dynamically adjustable counter comparison values offers flexibility in triggering interrupts to the PLC with sub-millisecond response.
