ELECTRICAL CHARACTERISTICS
Output on single-pole relay in deviation.
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.
