External Output
This equipment is able to output contact-originated signals when an alarm sounds or the power is
turned off. It is also able to output analog signals (represented by voltage) that indicate the
temperature of each incubation chamber and CO

concentration.
Alarm contact output
The output ports at the rear of the equipment can be connected with external devices, so that
signals are output when any of the alarms below sound.

Rated load of contact: 24 V DC, 1 A (for resistance load)
The output terminals are shown to the right.
Recommended connector (for connections)
Housing: SMR-04V-B (JST-made)
Pin contact: BYM-001T-P0.6 (JST-made)
* The cables to be connected must conform to the specifications presented by the manufacturers.

Output voltage
The output terminals are shown to the right.
Both COMs are single-end outputs.
Recommended connector (for connections)
Housing: SMR-18V-B (JST-made)
Pin contact: BYM-001T-P0.6 (JST-made)
* The cables to be connected must conform to the
specifications presented by the manufacturers.
Note: For measurement instruments to be connected, instruments with input impedance of 1 MΩ or
more is recommended.
If the connection cable length with the measurement instrument is too long, resistance in the
cable may lower the output.
In this case, using a device such as relay is recommended.
