PR-E-AI-V/I is an expansion module adding 4 analog input channels (0-10V/0-20mA) to PR series CPUs — flexible analog expansion for process signals.
Differences between PR-E-4AI-V/I and similar expansion modules:
PR-E-AI-V/I is a high-precision analogue input module with a resolution of 1mV for voltage signals and 0.003mA for current signals.

Address Setting for Expansion Modules
When multiple expansion modules are connected to one single CPU PLC, each expansion module must be assigned a distinct station address.
Factory default expansion address: 1. The expansion address is configured via DIP switch. The corresponding relationship between expansion address number and DIP switch status is shown below:
