Example of Connecting with a Coaxial Cable
A coaxial cable can be used in situations where the module is at a relatively large
distance from the external device or when the noise immunity of the module must be
improved. In this case, the current output and the analog ground for each channel are
connected to the load resistance R
L
of the external device by using the core wire and
the shield braid of the coaxial cable.

Notes!
- When the power is turned on or the module is reset, the current output signal will be
0 mA.
- To avoid any malfunction, the current output signal should not be connected to the
analog ground.
- To avoid any malfunction, the current output signal should not be connected to
another analog output signal or the output signal of an external device.
- To avoid any malfunction, the connector plug should not be attached or detached
when the power for the module or the external device is on.
- In situations where the connecting cable is subject to the effects of noise, the
accurate current output can fail.
- The connecting cable should be installed away from any source of noise.
