Product Description
Data Communications & Alarm Interface
Thermo Scientific Heratherm IMP 4-9
Data Communications & Alarm Interface
All signal connections are installed in the electrical interface panel at the rear of the
refrigerated incubator.
RS-232 Interface
The RS- 232 interface (item 2 in figure 4-9 below) may be used to connect Heratherm
refrigerated incubators to the serial interface port of a computer to allow for the
computer-aided acquisition and documentation of major operating parameters (temperature,
error codes, etc.).

Alarm Contact
The refrigerated incubator can be connected to an on-site, external alarm system (such as a
private branch telephone exchange, a facility monitoring system, visual or audible alarm
indicators). For this purpose, the devices come with a pre-wired potential-free alarm contact
(item 3 in
figure 4-9 )
.
The alarm contact is energized whenever an error occurs in an internal
control loop or the refrigerated incubator’s electrical circuits or hardware.
AC Power Socket
The refrigerated incubator is connected to the AC supply mains via the socket (item 4 in
figure 4-9 ), which accepts a power cord with an IEC standard plug.
Fuses
15 A device fuses
Two 15 A slow-blow fuses mounted on the refrigerated incubator’s main electronic circuit
board protect internal circuitry from the impact of excessive power consumption.
