It contains seven transistors, each able to carry up to 500mA (from memory). On the relays, make *sure* to use the diode across the coil to capture the collapsing field. I believe the ULN2003A datasheet is on our web site in the EDE1200 section. http://www.netins.net/showcase/elab -Todd Peterson E-Lab Digital Engineering, Inc.
