19.6 Analog output for temperature (option)
With this option the chamber is equipped with an analog output 4-20 mA for temperature. This output
allows transmitting data to external data registration systems or devices.
The connection is realized as a DIN socket (3) on the unit rear. A suitable DIN plug is enclosed.
ANALOG OUTPUT 4-20 mA DC
PIN 1: Temperature –
PIN 2: Temperature +
Temperature range: -10 °C / 32°F to +100 °C / 212°F

19.7 Zero-voltage relay control outputs (option)
The zero-voltage relay control outputs 1, 2 und 3 are used to switch any device connected via a DIN
socket on the unit rear. They permit turning on and off individually the connected devices by the
controller. They can be programmed in fixed value entry mode (chap. 7.3) as well as in the time program
editor (chap. 9.3.7) or the week program editor (chap. 10.3.6) via the operation lines.
The connection is realized as a DIN socket (4) on the unit rear. A suitable DIN plug is enclosed.
