This special serial cable allows RS485 communications between a Pfeiffer HiPace turbo pump TC drive unit and a Pfeiffer OmniControl or DCU controller. This interface cable has 4-pin, M12, round screw-type connectors on both ends. This cable is 3 meters long (10 ft.) and meets or exceeds OEM specs (OEM PN: PM 061 283-T3).

On TC 110 drive units, which have a 15-pin D-Sub (X3) connector, a power and communications adapter cable (part number P103335 or P1011168) is used to split out the X3 connector into a pump power cable and a short RS485 communication cable (terminated with an M12 connector). This 3 meter long RS485 cable attaches to and extends that short cable. The other end of this cable connects to the M12 round connector on an OmniControl or a DCU controller.

On TC 400 and TC 1200 drive units, which have a separate round M12 communications connector, this cable directly connects the drive unit to an OmniControl controller.

This Pfeiffer RS485 Communication Connector connects:

• TC 110 drive unit on HiPace 80 and 300H turbo pumps to an OmniControl 200 or DCU 110 controller (requires adapter cable P103335 or P1011168).
• TC 400 drive unit on HiPace 300, 350, 450, 700 and 800, to an OmniControl 300 or 400 controller (direct connction).
• TC 1200 drive unit on a HiPace 1200 turbo pump, to an OmniControl 001 controller (direct connction).
