vices.
The connection is carried out as a DIN socket (10) in the lateral control panel as following:
ANALOG OUTPUTS TEMPERATURE 4-20 mA DC
PIN 1: Temperature actual value –
PIN 2: Temperature actual value +
PIN 4: Temperature set-point value –
PIN 5: Temperature set-point value +
Temperature range: -40°C
/ -40°F
up to +180°C
/ -356°F
A suitable DIN plug is enclosed.
