Detailed Product Description

AI-301M works as On-Off signal I/O interface in a computer control system. It communicates
with computer through RS485 communication interface, and can provide cheap and high reliable
on-off signal or frequency signal input and relay output.

TECHNICAL SPECIFICATION
On-off signal input : photoelectric dry contact input, maximum withstanding voltage/current is
35V/1mA.
On-off signal output: relay contact switch, 250VAC/1A or 30VDC/1A
Power supply : 100240VAC, -15%, +10% / 50-60Hz; or 24VDC.
Power consumption : ≤2W
Operating Ambient : temperature -1070 ; humidity ≤90% RH

AI-301 series instruments apply AIBUS communication protocol. The instruments in the
same communication line should have different communication address, and LAN can be built
between computers. AIBUS communication protocol v7.0 was free to provide.
