Request Info
The Power and Data Interface Module (PDIM) to provides power and real-time data acquisition for an SBE 19, 19plus, 19plus V2, 25, 25plus, or 49 CTD, or SBE 50 Pressure Sensor when connected to an SBE 33 deck unit. The SBE 33 remains at the surface while the PDIM is installed on or near the CTD (CTD refers to the listed CTDs as well as the SBE 50 Pressure Sensor). The system allows for two-way communication for the CTD over a single- or multi-conductor sea cable, and provides ample power for auxiliary sensors that may not otherwise be supportable by a battery-powered CTD.

PART # DESCRIPTION NOTES
PDIM

Underwater Power/Data Interface Module - accessory for SBE 19/19plus/19plusV2/25/25plus CTDs. Converts surface power for use by CTD and provides two-way communication interface between CTD and Deck Unit via single-conductor armored cables up to 10,000 meters long. Includes Seasoft software and complete documentation. Requires use of SBE 33 or SBE 36 Deck Unit - ordered separately. Does not include interface cables or mounting hardware – ordered separately.

PDIM is required to interface SBE 36 Deck Unit with CTD. PDIM housing is anodized aluminum, & is rated to 6800 m. PDIM order includes sea cable extension cable & pigtail cable, dummy plugs, & jackscrew kit. To order PDIM mount kit & CTD interface cable, see SBE 36 Accessories & Spares above.

Note: PDIM can also be used with SBE 33 Carousel Deck Unit (when used without an SBE 32 Carousel Water Sampler), to provide same functionality as when used with SBE 36 Deck Unit.
PDIM Connectors Selections — MUST SELECT ONE
PDIM.11 XSG connectors PDIM connector type (XSG or wet-pluggable MCBH) must match CTD connector type. Wet-pluggable connectors provide easy connectability in damp (e.g., rolling, slippery deck) or cold environments (XSG connectors may not seal well in extreme cold; we recommend connecting cables in warm ship’s lab rather than on deck for these conditions). Wet-pluggable connectors are not meant for literally plugging cables in submerged underwater; both our XSG connectors & wet-pluggable connectors must be mated in air.
PDIM.12 Wet-pluggable MCBH connectors
