The CPSN‑CNT‑3201I2 counts two‑phase signals from encoders and linear scales with 500 kHz response. Opto‑isolated inputs, match output with interrupt, digital filter, and synchronization function. Wide temperature range (-20 to +60°C) and tool‑less installation. From Contec Americas. 32 Bit Counter 500 kHz Response 1500 V Isolation ‑20 to +60°C Operation Contec Americas · CONPROSYS nano CPSN‑CNT‑3201I2 32‑Bit Counter · Opto‑Isolated · Two‑Phase Counting View Collection 01 High‑Speed 32‑Bit Counter for Encoders The CPSN‑CNT‑3201I2 is an expansion I/O module for the CONPROSYS nano series, adding a 32‑bit up/down counter interface. It counts two‑phase signals (A/B) and single‑phase signals from encoders and linear scales with a response frequency of up to 500 kHz. The module features opto‑isolated inputs, a match output with interrupt capability, and a digital filter for noise rejection. Counter Features 32‑bit up/down counting 500 kHz response Two‑phase or single‑phase Opto‑isolated (1500V) Match output with interrupt Key Features ‑20 to +60°C operation Tool‑less installation Digital filter Zener diode surge protection LED status indicators Match output – generates a one‑shot pulse or interrupt when the count value matches a user‑set value. The output pulse width is software‑configurable. General‑purpose input and output are also available for flexible system design. 02 Built for Harsh Industrial Environments Designed for demanding factory automation, position sensing, and motion control applications. The CPSN‑CNT‑3201I2 operates across a wide temperature range (-20 to +60°C) and features opto‑isolated inputs for noise immunity. The module installs and removes without tools, simplifying system maintenance. Wide temperature range – Operates from -20 to +60°C for installation in diverse environments. Opto‑isolated inputs – 1500V isolation protects the system from noise and ground loops. Digital filter – Programmable filter prevents false counting due to noise or chattering. Surge protection – Zener diode on output circuit protects against voltage surges. Tool‑less installation – Easily install and remove from the CPU unit without any tools. 03 Full Specifications Specification Detail Model CPSN-CNT-3201I2 Counter channels 1 channel Count system Up/down counting Max count FFFFFFFFh (32‑bit binary) Counter input type Opto‑isolated (current sink compatible, positive logic) Isolation Opto‑coupler isolation (1500V) Counter input signals Phase‑A/UP, Phase‑B/DOWN (1 each) Input resistance (5V/12V/24V) 900Ω / 2.7kΩ / 5.7kΩ Input ON current 1.77mA or more Input OFF current 0.47mA or less Response frequency 500 kHz max (duty 50%) Interrupt Count match or timer time‑out External power 5V±5% or 12V±10% or 24V±10%, min. 200mA Digital filter 0.1µsec – 52.4288ms General‑purpose input 1 channel, opto‑isolated (negative logic) Control input signals Preset, Zero‑clear, Counter start/stop Match signal output 1 channel, opto‑isolated open collector Output rating 35VDC max, 50mA per point Output protection Zener diode (CMZB47 or equivalent) Connector 10‑pin terminal (3.81mm pitch) Applicable wire AWG28 – 16 Current consumption 0.1A max Dimensions (mm) 15.6(W) × 52.6(D) × 84(H) (excluding protrusions) Weight 50g Operating temperature -20 to +60°C (depending on installation angle) Operating humidity 10 – 90%RH (no condensation) Standards VCCI Class A, FCC Class A, CE (EMC Class A, RoHS), UKCA, ISED Included items Product, 10‑pin connector, manual Datasheet version As of March 2026 04 Optional Accessories Product Name Model Description Remote I/O CPU unit (4‑slot) CPSN-MCB271-S1-041 LAN 1‑channel Remote I/O CPU unit (8‑slot) CPSN-MCB271-1-041 LAN HUB Remote I/O CPU unit LAN HUB, 8‑slot CPSN-MCB271-1-081 — CODESYS Modbus Master CPU unit CPSN-PCB271-S1-041 — Remote I/O CPU unit EtherCAT, 4‑slot CPSN-E0B471EC-41 — Remote I/O CPU unit EtherCAT, 8‑slot CPSN-E0B471EC-81 — USB I/O Unit – Module Type (4‑slot) CC-LSB271-CPSN4 — DIN rail fitting power supply 30W CPS-PWD-30AW24-01 Input: 100‑240VAC, Output: 24VDC 1.3A DIN rail fitting power supply 90W CPS-PWD-90AW24-01 Input: 100‑240VAC, Output: 24VDC 3.8A Visit the CONTEC website for the latest optional products and compatible CPU units. 05 Certifications and Compliance VCCI Class A — Japanese voluntary control for electromagnetic interference (commercial/industrial environments).
