* 24VDC Specification: 24VDC 60W; Residual ripple 100mV; Spikes/switching Peaks 240mV; Turn On/Off response;
No overshoot of V out; Overvoltage voltage protection output voltage must be clamped to <30Vdc
#1
The programmed digital input setting on D1COM, D1-1I, D1-2I must correspond to the voltage applied to these
terminals to avoid risk of damage to the equipment.
#2
The programmed digital input setting on D2COM, D2-1I must correspond to the voltage applied to these
terminals to avoid risk of damage to the equipment.
#3
The control supply can be 110 to 230VAC applied to the N, L terminals or 24VDC applied to the 0VDC, 24V input
terminals. The correct voltage as specified must only be applied to one of these supply inputs to avoid risk of
damage to the equipment.
