With the IPC/REL12 PC/104 expansion card, twelve relay outputs of 24 or 48 volts can be added to the Syslogic industrial PCs. The switching current is two amps. The IPC/REL12 expansion card also has eight transistor outputs (open collector). As on the embedded computers, the Syslogic expansion cards meet stringent industrial standards. The IPC/REL12 cards are equipped with overvoltage protection and are designed for an extended temperature range of between –40 and +85 °C.
