Easy integration into automatic testing equipment (RM3544-01)
High-speed, comprehensive productivity
support
• The RM3544-01 delivers the speed demanded by automatic test-
ing equipment at a sophisticated level. The entire process from the
start of measurement to outputting of the judgment result takes as
little as 18 ms. One cycle of operation, lasting from measurement
to judgment output, completes within this time.
• The RM3544-01 supports RS-232C data communications at up to
115.2 kbps.
• The instrument’s USB interface can also be used.
• The EXT I/O output mode can be switched between judgment
mode and BCD mode.
Functionality for verifying the EXT I/O con-
nection status and testing EXT I/O
In addition to allowing you to check EXT I/O signal input on the in-
strument’s screen, this functionality allows you to turn output signals
on or off as desired. This capability simplifi es verifi cation work dur-
ing PLC programming.
Handler (EXT I/O) interface
The handler interface (EXT I/O) is isolated from measurement cir-
cuitry, control circuitry, and the protective ground (chassis ground),
providing a high level of noise resistance.

A switch on the rear panel is used to toggle the input signal polarity between NPN
(sink output support) and PNP (source output support) settings depending on the
PLC common polarity.
