* add suffix "/H4" for 4kVDC isolation and "/H6" 4:1 Input for 6kVDC isolation (REC3-S/DRWZ(H4/H6)) A C add suffix "/A" or "/C" for Pinning, see next page xx = 9-36Vin = 24 B "B" Pinning is NOT available for this series ! xx = 18-72Vin = 48 M add suffix "/M" for metal case e.g. REC3-2412SRW/H4/AM = A 4kVDC isol. / Pinout "A" / metal case
Notes :
M 1. If the options "/M" for metal case and S "/SMD" for SMD pinout are combined the maximum allowed isolation voltage is 2kVDC because of the shoter distances between pins and metal-case, so only available SMDH option in metal-case is "/H2". DIP-24 through-hole case and SMD-plastic case are not affected and offer the desired isolation barriers of 4kVDC for "/H4" option and 6kVDC for "/H6".
Description
This series offers high isolation of 4kVDC (= option "H4") or 6kVDC (= option "H6") making it ideal for medical applications and other sophisticated industrial applications. UL-1950 approval of this series is is applied for. Packaging can be either DIP-24 non-conductive plastic or 5-side-shielded DIP24 metal case (= option "M") as well as DIP24-SMD case (= option "SMD"). For all the above variants, 2 industry-standard-pinouts (= option "A" or "C") are available.
