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 SUPPLY +
and–terminals.When/ALisspecied,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specied.
Connect wiring for external indicators to the CHECK
(+) and SUPPLY – terminals.
(Note)Useaexternalindicatorwhoseinternalresistanceis10Ω
or less.

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