Contact rating 16(4)A 240 Va.c. for each output (L03BI1A-L03BI2A). Contact rating 12(3.6)A 240 Va.c. for each output (L03BM1B-L03BM2B). Power consumption 3W. REGULATIONS AND APPROVALS Compliant with EN60730-1; EN60730-2-9; EN55022 (Class B); EN50082-1. INSTALLATION DIN rail mounting. OPERATION Type of control: can operate in ON/OFF or PID mode. Temperature alarm management for output 2 (models L03BI2A and L03BM2B only).). ON/OFF control: in ON/OFF mode, the output is ON or OFF depending on the input temperature, setpoint (1SP) and hysteresis value (1HY). Hysteresis indicates the magnitude of the setpoint temperature deviation to reactivate the output. PID control: in PID mode the output is ON for a fraction of cycle time 1CT. The cycle time characterises the dynamics of the system to be controlled and influences the accuracy of the control. Proportional control. Integrative proportional control. 10  HEATING ON/OFF CONTROL ON/OFF CONTROL IN COOLING The heating output switches off when the The heating output switches on when the temperature is above the setpoint temperature is above the setpoint TEMPERATURE TEMPERATURE SP SP HY The output is ON when the The output is temperature is OFF when the below the setpoint temperature OUTPUT OUTPUT + hysteresis is below the setpoint + hysteresis TIME TIME PROPORTIONAL CONTROL (P) PROPORTIONAL-INTEGRATIVE CONTROL (PI) IN HEATING IN HEATING Overshoot Overshoot steady-state error SP SP TEMPERATURE TEMPERATURE proportional band integral control proportional band band process process temperature temperature TIME TIME PROPORTIONAL-INTEGRATIVE-DERIVATIVE (PID) HEATING CONTROL Overshoot L SP TEMPERATURE proportional band process temperature TIME FEATURES NTC10k inputs. Configurable parameters: „ cooling or heating function by assigning positive or negative sign to the differential or proportional band respectively; „ minimum or maximum setpoint limits; „ ON or OFF status of the output in the event of a defective probe; „ minimum ON/ OFF time of the output independent of the temperature value „ absolute or relative temperature alarms of output 2 (models with two outputs only). Operating temperature -10 to 50°C. Degree of frontal protection IP40 if correctly installed on back of panel. ON/OFF button on the front.
