CAUTION
●Notes of input wire
・Please do not mix the noise about the input wiring. Moreover, the use of an effective shield
line or twist line is recommended to the noise in the input wiring.
・At the thermo-couple input, please connect thermoelectricity vs. wire directly or use the
protective conductor. The use of the input line with the shield is recommended.
・At the resistance temperature sensor input, the difference of the line resistance in three lines
is assumed below the following. The use of the input line with the shield is recommended.
Pt100, JPt100: Under 50mΩ.
・When there is a possibility of receiving the influence by the inductive noise, especially,
when wiring near the high frequency power supply, the use of the twist line with the shield
is recommended.
・Please install round shape pressure connection terminal (for M3.5) to which the insulation
sleeve attaches on the electric wire terminal.
・If you want to use by branching the input wiring, please use it with the setting of burnout
“OFF”. If the setting of burnout “ON”, may have influence to equipment.
●Notes in wiring
・Please separate from the power supply circuit (power supply or DO circuit of 25V or more)
and use this equipment and wiring between measurement points.
・
Please ground the shield of the shield line.

[Connector]
For DIDO, a 40-pin MIL compliant connector plug is used.
Therefore, we recommend the following for the cable side connector.
- HIROSE ELECTRIC CO., LTD
HIF3BA-40D-2.54R(Socket, Pressure welding) or HIF3BA-40D-2.54C(Socket, Crimping)
The DI/DO cable (WMSU0468A01: cable length 1m, WMSU0468A02: cable length 3m) is available as
an option.
For details, please contact to state of the purchase, or our salesperson.
Refer to below table for signal arrangement of the cable.
