23. THE CONTROLLER Power Supply Recommendations Opto 22 recommends that the SNAP PAC S series controller be powered with an Opto 22 SNAP PS24 or SNAP PS24U power supply In place of one of these power supplies Opto 22 recommends an 8 32 VDC linear supply with adequate current ratings for the load For more information on power requirements see Specifications on page 51 Change to SNAP PAC S1 Power Input Range Current SNAP PAC S1 controllers have an 8 32 VDC input range but earlier SNAP PAC S1 controllers use an 8 24 VDC input range Before applying power to the controller confirm that the input voltage is within the voltage range shown on the faceplate The voltage input rating can also be determined based on the SNAP PAC S1 s serial number as follows SNAP PAC S1 controllers with serial number 500000 and higher have an 8 32 VDC voltage input rating SNAP PAC S1 controllers with serial numbers lower than 500000 have an 8 24 VDC input rating Using an input voltage above this range will cause damage that is not covered by the warranty The SNAP PAC S1 serial number appears on the sticker on the side of the unit The input voltage rating is shown on the top cover of the controller P Address IP Address MAC 1 00 A0 3D 00 XX XX MAC 1 00 A0 3D 00 XX XX e SNAP PAC S1 o 7 ce wummum O C input voltage rating x SNAP PAC S1 serial number p e svoc SNAP PACS Installing Hardware
