GENERAL
The SALD mV and Temperature Alarm Unit accepts a
mV DC, thermocouple or RTD input signal, compares
the input signal with an alarm setpoint, and outputs an
alarm signal. One or two absolute alarm outputs can
be provided on one input. Direct/reverse action can
also be set to each of the alarm setpoints. Alarm LED
is provided on the front panel for confirming alarm relay
action (when relay is energized).
The JHT200 Handy Terminal*
is used for setting the
Alarm Unit parameters. For the SALD with display
setter (SALD-

4), input indication and alarm setpoints
can be set on the front panel.
*: When connecting the JHT200 Handy Terminal, the
adapter for modular- jack (model E9786WH) is required.
When using the BT200 BRAIN Terminal of YOKOGAWA
Electric Corporation, the communication cable of 5-pin
connector type (model F9182EE) and the adapter for
modular-jack (model E9786WH) are required.
