6.3 Analog Outputs OUT1 - OUT4
Comm Box: DIN 6TE, analog (4 channels)
Source: object temperature / head ambient temperature
Signal: 0/4 to 20 mA or 0 to 5/10 V
Terminal: I

Each signal output can be configured as either current or voltage output, whereby each sensing head
can be assigned to each output. The minimum load impedance for the voltage output must be 10
kΩ.
The maximum current loop impedance for the mA output is 500 Ω. All outputs are short circuit
resistant.
6.4 Alarm Output RELAY
Comm Box:
all models
Source: object temperature / head ambient temperature
Signal: potential-free contacts
Terminal: RELAY, RELAY
The alarm output is controlled by the target object temperature or the head ambient temperature. In
case of an alarm, the output switches the potential free contacts from a solid state relay. The maximum
load for this output is 48 V / 300 mA.
If a spike voltage exceeding the absolute maximum rated value is generated between the output
terminals, insert a clamping diode in parallel to the inductive load as shown in the following circuit
diagram to limit the spike voltage.

Each output is galvanically isolated from the other and from the power supply!
Powering the communication box (DIN, 6TE), analog, only via USB will disable all
analog outputs! The configuration of the box under the control panel is furthermore
possible. Under the DataTemp Multidrop you can only drive and configure the analog
outputs by using an additional external power supply!
