Two External Inputs and Eight External Outputs with Many Operating Modes

• Max. input frequency = 500 kHz for line-driver input.
• 32-bit counting range.
• 2- and 4-axis operation available.
• Digital variable noise filter provided.
• 5-, 12-, and 24-V line driver inputs available. (5- and 12-V line
driver input is only available, however, for 1 axis with the CS1W-
CT021 and 2 axes with the CS1W-CT041.)
• Supports simple, ring, and linear counting modes.
• Supports offset phase input, up and down pulse input, and
pulse+direction input.
• Supports 4 external control inputs, and a total of 16 functions
can be set including open gate, close gate, preset, reset, cap-
ture, stop/capture/reset combinations, and reset enable.
• One Unit supports 4 external outputs and 28 internal outputs
with counter value zone comparisons, target comparisons, de-
lays, holds, programmable outputs, and hysteresis settings.
• Pulse rate measurement function and data logging.
• Counter outputs and external control inputs can be used to trig-
ger interrupt tasks in the CPU Unit.
• Settings can be changed during Unit operation.
