The tiny TOOLS SRC-2X interfaces two optically isolated inputs and two SPST relays to a 10/100baseT Ethernet port. The SRC-2X can notify a users PC software program that any of two optically isolated inputs have been opened or closed and allows your software to control two SPST, 1-amp relays. Communication with the SRC-2X is accomplished via short "burst" type ASCII commands from the users PC. Also, two units may be operated in a standalone mode (master/slave mode) to form an "Ethernet (Internet) relay extension cord with two channels of control in each direction. Configuration is via most web browsers.

The SRC-2X is powered by a surge protected internal power supply. The SRC-2X may be rack mounted on the optional RA-1 mounting shelf (sold separately).
