SNAP-LCM4 User’s Guide

POWER SUPPLY RECOMMENDATIONS
The power supply used for the SNAP-LCM4 controller should
not
be used to supply any other equipment.
Field devices must
not
be supplied by the same power supply used for the controller, as the optical isolation
of the I/O modules would be bypassed and voltage fluctuations to the controller might cause controller resets.
Opto 22 recommends that the SNAP-LCM4 be powered with an Opto 22 SNAP-PS5 or SNAP-PS5-24 power
supply. The controller requires only 5 VDC. The total amount of current required depends upon the expansion
cards installed (see the table on page
); the controller itself requires 1.0 amp.
Third-Party Power Supply Vendors
If you are not using an Opto 22 power supply, use only good quality power supplies that offer tight voltage
regulation. Opto 22 recommends a linear supply with adequate current ratings for the load. The following
vendors carry suitable third-party power supplies:
