Binder KBF 720 (E5.2) - Analog Outputs for Temperature and Humidity (Option)

KBF / KBF P (E5.2) 02/2012 page 73/103
15.4 Analog outputs for temperature and humidity (option)
With this option the chamber is equipped with analog outputs 4-20 mA for temperature and humidity. The-
se outputs allow transmitting data to external data registration systems or devices.
The connection is realized as a DIN socket (6) in the right lateral control panel as follows:
ANALOG OUTPUT 4-20 mA DC
PIN 1: Temperature –
PIN 2: Temperature +
PIN 3: Humidity –
PIN 4: Humidity +
Humidity range: 0 % r.H. to 100 % r.H.
Temperature range: -10 °C / 14 °F to +100 °C / 212 °F
A suitable DIN plug is enclosed.

15.5 Zero-voltage relay alarm outputs for temperature and humidity (option)
The chamber equipment with optional zero-voltage relay outputs for temperature
and humidity (option) permits the transmission of alarms to a central monitoring
system. Connection is established via a DIN socket (7) located on the right lateral
control panel.

Pin 1: Pin
Pin 2: Make
Pin 3: Pin
Pin 4: Make
In case of a temperature alarm, pins 1 and 2 are open; with humidity alarm, pins 3 and 4 are open. This
happens simultaneously with the alarm message shown on the controller display.
In case of power failure, both contacts are open.
Maximum loading capacity of the switching contacts: 24V AC/DC - 2,5A
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.
A temperature and humidity alarm message will remain visible on the controller display during the whole
time of the alarm transmission via the zero-voltage relay outputs.
As soon as the cause of the alarm is rectified, you can reset the alarm transmission via the zero-voltage
relay outputs together with the alarm message at the controller display by pressing the “RESET” key.
In case of power failure, transmission of the alarm via zero-voltage relay outputs remains active for the
duration of the power failure. Afterwards, both contacts will close automatically.
