15.4 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 following:
ANALOG OUTPUT 4-20 mA DC
PIN 1: Temperature –
PIN 2: Temperature +
Temperature range: 0 °C to 300 °C
A suitable DIN plug is enclosed.
Figure 12: Pin configuration of the DIN socket
15.5 Zero-voltage relay outputs via operation lines (option)
Operation lines 1, 2 und 3 are used to switch any device connected to the zero-voltage relay outputs via
a DIN socket at the rear of the incubator. The operation lines permit turning on and off the individual zero-
voltage relay outputs through the program controller. They can be programmed in fixed value entry mode
(chap. 6) as well as in the program editor (chap. 8.2) via the operation lines (switching state 0 = Off,
switching state 1 = On).
Connection occurs via the DIN socket at the rear of the chamber as following:

Maximum loading capacity of the switching contacts: 24V AC/DC – 2.5 A
DANGER
Electrical hazard.
Danger of death.
Damage to switching contacts and connection socket.
∅ Do NOT exceed the maximum switching load of 24V AC/DC – 2.5A.
∅ Do NOT connect any devices with a higher loading capacity.
15.6 HEPA fresh air filter (option)
With this option, the introduced fresh air is cleaned by means of a high efficiency submicron particulate
air filter type HEPA class H 14 (acc. to DIN EN 1822:2009). Replace the filter insert, if necessary, by
removing the metal cover of the filter at the left side of the chamber (Art. No. 6014-0003).
