Both Output and Input Blocks must be provided with an external power sup-
ply. (They do not contain built-in power supplies.) For Output Blocks, the re-
lay drive power supply must be connected to the positive and negative termi-
nals. On the load side (points 0 through 15), power supplies must be pro-
vided to drive the loads. For Input Blocks, power must be connected to the
positive and negative terminals, and the relay drive power supply must be
provided to individual input points (points 0 through 15).
Use the connecting cable to supply power from each I/O Block power termi-
nal to its Remote Interface. Do not supply power to the I/O Block until it has
been connected to its Remote Interface.
