12.4 Analog output for temperature (option)
With this option the chamber is equipped with an analog output 4-20 mA for temperature. This output
permits transmitting data to external data registration systems or devices.
The connection is carried out as a DIN socket at the rear of the chamber as follows:
ANALOG OUTPUT 4-20 mA DC
PIN 1: Temperature –
PIN 2: Temperature +
Temperature range:
BD, BF: 0 °C / 32 °F to +100 °C / 212 °F
ED, FD, FED: 0 °C / 32 °F to +300 °C / 572 °F
A suitable DIN plug is enclosed.

12.5 Water protected disconnectable internal socket (option BD, BF)
You can turn on or off the disconnectable water protected internal socket (CA3GD) for line voltage inside
the chamber by the switch in the triangular instrument panel, independent of the incubator operating or
not. Thus, devices operated inside the incubator can be started or stopped without any need to open the
chamber doors.
The internal socket provides a protective conductor, therefore it is possible to connect appliances with
protection class I.
The internal socket is splash proof.
IP system of protection 67 230 V 1N ~ 50-60 Hz. Charge max. 500 W
Maximum permitted operating temperature with this option: 90 °C / 194 °F.
WARNING
Exceeding of the permitted maximum temperature.
Electrical hazard.
Danger of death.
Damage to the internal socket.
∅ Do NOT exceed the temperature set-point of 90 °C / 194 °F.
Set the safety controller class 3.1 to 90 °C / 194 °F.
Heat emission of electrical devices connected inside the chamber may modify the temperature
range.
CAUTION
Risk of short circuit.
Damage to the chamber.
Use the delivered plug only (IP protection type 66). Plug-in the plug and turn it to se-
cure.
If the socket is not used, close the lift-up lid and turn it for securing.
