6.3.1 Power Supply Wiring Connection
IMPORTANT
Connecting with the commercial AC power
supply will damage the device. Be sure to use
the DC power supply in the predetermined
range.
Connect the power supply wiring to the
and – terminals. When /AL is specified, also refer to
subsection 6.3.5.

6.3.2 External Indicator Connection
Available only for 4 to 20mA output type and when
/AL is not specified.
Connect wiring for external indicators to the CHECK
(+) and SUPPLY – terminals.
(Note) Use a external indicator whose internal resistance is 10 Ω
or less.

6.3.3 Communicator Connection
■ 4 to 20 mA output, BRAIN / HART
IMPORTANT
Analog output may change temporally in
connecting with BRAIN terminal due to an initial
current flowed to it. To prevent communication
signal affecting the upper system, it is
recommended to install a low-pass filter
(approximately 0.1s)
Connect the BT200 or HART Communicator to the
and – terminals. (Use hooks.)
