常见问题 (FAQ)
Q1: What type / load is the 2MLQ-SS2A suitable for?
A1: It is designed for resistive and inductive AC loads such as contactors, solenoids, and pilot lamps.
Q2: Is the output electrically isolated from the controller?
A2: Yes, it uses photo-coupler isolation to separate control logic from output circuits.
Q3: Can I use this module for DC loads?
A3: No, it is specifically designed for AC voltage loads.
Q4: What happens if the load current exceeds 0.6A per point?
A4: Exceeding rated current may damage the triac; protective devices like fuses should be used externally.
Q5: Does the module have built-in surge protection?
A5: Yes, it features a varistor and C.R absorber to suppress voltage spikes.
Q6: Can the module be hot-swapped?
A6: No, power should be removed before replacing or removing the module.
Q7: Is there LED indication for each output channel?
A7: Yes, an LED lights up when the respective output channel is active.
Q8: Can this module operate at 50Hz and 60Hz?
A8: Yes, it supports both 50Hz and 60Hz AC frequencies.
Q9: Is there any delay in switching OFF the load?
A9: Yes, the OFF response includes 0.5 cycle plus 1 ms delay.
Q10: Can the module be used in harsh industrial environments?
A10: Yes, but conformal coating is recommended for G2/G3 level environments.
