WARNING

NOTE

Input characteristics:

 

Input signal

: Dry contact, open-collector (TTL or transistor) signal

Control functions and signal types:

 

 

• Recording start/stop

level

 

• Chart speed change

level

 

• Printout messages

trigger more than 250 msec

Signal characteristics

: ON voltage

0.5 V or less (30 mA DC)

 

Leakage current in OFF state

0.25 mA or less

 

Signal duration

250 msec or more

Input types

: Photocoupler isolation (one line common)

 

Internal isolated power source (5 V±5%)

Dielectric strength

: 500 V DC for one minute between input terminals and

 

grounding terminal.

 

To prevent an electric shock, ensure the main power switch is turned off before wiring.

Use shielded cables for remote control signals to prevent noise pickup. The shield should be grounded at the recorder’s terminal.

To prevent an emission of electromagnetic disturbances, separate the remote control wires from the power supply and input wires at least 0.1 m. Over 0.5 m is recommended.
