From Contec Americas. 4 Differential Inputs 16 Bit Resolution ±20V Max Voltage Input ‑20 to +60°C Operation Contec Americas · CONPROSYS nano CPSN‑AI‑1604LI 4‑Ch 16‑Bit Analog Input · Differential · Voltage/Current View Collection 01 High‑Precision Analog Input for CONPROSYS nano The CPSN‑AI‑1604LI is an expansion I/O module for the CONPROSYS nano series, adding 4 channels of 16‑bit differential analog input. The module supports both voltage and current input — switchable per module via on‑board switch — and input ranges are software‑selectable. Bus isolation (500VDC) ensures reliable measurement even with potential differences between the module and signal source. Analog Input 4 differential channels 16‑bit resolution Voltage or current input Software‑selectable ranges Bus isolated (500VDC) Key Features ‑20 to +60°C operation Tool‑less installation No electrolytic capacitors Differential input 10‑pin terminal connector Differential input – accurate measurement even when potential differences with the signal source occur. Voltage and current input are switchable via the on‑board switch, with ranges set by software. 02 Built for Harsh Industrial Environments Designed for demanding factory and process automation applications. The CPSN‑AI‑1604LI operates across a wide temperature range (-20 to +60°C) and is built without electrolytic capacitors for extended product life. The module installs and removes without tools, simplifying system maintenance. Wide temperature range – Operates from -20 to +60°C for installation in diverse environments. Long life design – No electrolytic capacitors, which have limited operational life. Tool‑less installation – Easily install and remove from the CPU unit without any tools. Bus isolation – 500VDC isolation protects the system from ground loops and transients. Compact form factor – 15.6(W) × 52.6(D) × 84(H) mm, weight only 50g. 03 Full Specifications Specification Detail Model CPSN-AI-1604LI Input type Differential input Input channels 4 channels Input ranges (voltage) ±10V, ±5V, ±2.5V, 0‑+10V (software selectable) Input ranges (current) ±20mA, 0‑20mA, 4‑20mA (software selectable) Maximum input rating (voltage) ±20V Maximum input rating (current) ±30mA Input impedance (voltage) 1MΩ or more Input impedance (current) 249Ω (typical) Resolution 16 bits Non‑linearity error (voltage) ±8 LSB Non‑linearity error (current) ±20 LSB Channel switching rate 10 µsec/ch Conversion rate Varies by software Buffer memory — Conversion start trigger Software Isolation Bus isolation (500VDC) Connector 2 pieces, 3.81mm pitch, 10‑pin terminal Applicable wire AWG28 – 16 Power consumption 5V 0.25A (max), 3.3V 0.01A (max) Dimensions (mm) 15.6(W) × 52.6(D) × 84(H) (excluding protrusions) Weight 50g Operating temperature -20 to +60°C 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 February 2026 04 Optional Accessories Product Name Model Description Remote I/O CPU unit (4‑slot) CPSN-MC8271-S1-041 LAN 1‑channel Remote I/O CPU unit (8‑slot) CPSN-MC8271-1-041 LAN 2‑channel Remote I/O CPU unit LAN 2‑channel, 8‑slot CPSN-MC8271-S1-081 — CODESYS Modbus Master CPU unit CPSN-PC8271-S1-041 — Remote I/O CPU unit EtherCAT, 4‑slot CPSN-EQ8471EC-41 — Remote I/O CPU unit EtherCAT, 8‑slot CPSN-EQ8471EC-81 — USB I/O Unit – Module Type (4‑slot) CC-USB271-CPSN4 — DIN rail fitting power supply 30W CPS-PWD-30/4/24-01 Input: 100‑240VAC, Output: 24VDC 1.3A DIN rail fitting power supply 90W CPS-PWD-90/4/24-01 Input: 100‑240VAC, Output: 24VDC 3.5A 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).
