The TM7 System consists of IP67 I/O blocks along with field bus, expansion, sensor/actuator and power cables.
A TM7 I/O block can be a:
odigital I/O block, for details, refer to the Modicon TM7 Digital I/O Blocks Hardware Guide
oanalog I/O block
oPower Distribution Block (PDB), for details, refer to the chapter TM7SPS1A Power Distribution Block (PDB) in the Modicon TM5 / TM7 Flexible System - System Planning and Installation Guide
