Selection Notes

The 24V/60V DC rating and 1A per-contact limit size this module for analog I/O signal wiring rather than digital output switching loads — select it specifically for S7-1500 analog modules that use 40-pole front connectors. The 30 m maximum wire length between the front connector module and the terminal module sets the practical cabinet-to-terminal-strip distance when wiring with SIMATIC TOP Connect.

Applications

Used in SIMATIC S7-1500 automation systems where analog I/O modules are pre-wired through SIMATIC TOP Connect terminal modules, typical in panel-built machine control and process instrumentation cabinets where reducing point-to-point field wiring errors matters.
