Recording paper illumination: Cold cathode fluorescent lamp

Alarm output external control: Special-purpose unit needed. Unit can be mounted in rear of in-
strument as extra equipment at a later date.
(1) Alarm output (DO):
6 or 12 point of relay contact output (1a), can be for individual chan-
nels or perform OR operation.
Relay contact capacity: 240V AC, 3A (resistive load),
30V DC, 3A (resistive load)
(2) External control (DI): The following functions can be performed in response to external con-
tact signals:
• Recording operation start/stop (DI 1):
Contact signals can start/stop recording operations. Recording starts when contact is closed
and stops when contact is open.
Message print is started when DI1 is specified. It is also started during recording when the
contact is closed.
• 2-stage change of chart speed (DI 2):
Contact signals can effect a change from normal recording paper feed speed to remote mode
chart speed. Closing the contact gives remote mode chart speed.
Opening the contact gives normal chart speed.
But, message printed when DI2 has been specified. During recording, message print is
started when the contact is closed.
• Instantaneous value print-out (DI 3)
Instantaneous value lists (dates, times, channel Nos., measured values, units) are printed out
in response to contact signals. Print-out starts when the contact is closed and stops when the
contact is opened.
But, latch is OFF when alarm latch function is ON. It is also OFF when the contact is
closed.
Note: As the external control unit is not insulated, use it with insertion of an external relay.
Contact capacity: 12V DC, 0.05A 1a contact

Transmission function: RS-485 interface or T-link
Serves to transmit measured values and receive specified conditions.
RS-485
Note: For connection through RS-232C,
Use a 232/485 converter.
Use of the following converter is
recommended:
