753-1629

These active spacer modules provide both hardware and software space reservation for standard function modules (digital/analog) in PROFIBUS networks (only in connection with the 750-333 Coupler). 753 Series Pluggable Connectors enable the use of pre-wired connection cables. The spacer modules also simulate a function module and are configured accordingly (select module “optionally not plugged”). Subsequent node expansion is made possible by replacing spacer modules with function modules without disturbing existing wiring or configuration. These modules are available with and without power jumper contacts for power supply to downstream modules.
