Description:

The PRL-MRK-3-1 modular rackmount kit enables rapid assembly of custom systems from an assortment of PRL Mini Modular Instruments (MMIs). Multiple MMIs may be mounted, powered, and cabled together in minutes, providing a rugged, reliable solution for creating one-of-a-kind systems, prototype systems, lab systems, etc.

The chassis front and rear panels have cutouts for mounting any MMI with a 1.3” x 2.9” cross-section (PRL 970 series). To mount a module, remove the 4 screws from one endplate, place the MMI inside the rackmount kit, and then secure it to the panel with the endplate screws. Up to 31 modules and/or adapter plates may be mounted in the kit (with the optional mid-panel) subject to power requirements.

Modules may also be mounted on a defined grid inside the chassis using our standard mounting brackets (PN 35001420), or anywhere inside the chassis via 3M Dual-lock™ fastener strips. Use one coarse and one fine strip for removable/reconfigurable mounting or two fine strips for virtually permanent installation.

If a module is mounted with its DC input jack on the outside of the chassis, a PRL-730 voltage distribution module may be mounted to the panel to route power to the outside of the chassis for up to 4 modules.

To route signals from inside the chassis to the outside, a bulkhead adapter plate may be used for signal pass-through. Adapter modules may be used to convert connector types, such as Triax to/from dual SMA, or SMA to/from RJ-45.

Modules with remote-control, such as the PRL-854-RM series of switches, can be programmed via TTL control pins or over USB via the PRL-USBIO-1 controller module. A TCP/IP controller module (PRL-EthIO-1) is coming soon.

Installed in each kit is a ±8.5 V, ±2.2 Amp internal power supply with 10 DC supply jacks, compatible with nearly all 970-series MMIs (see details, here). The AC input is 120/220 VAC switchable and fused, with an external grounding post. .

Mounting positions on the front, rear, and mid panel support any PRL module with dimensions of 1.3W x 2.9H and any length.

Bottom panel grid positions for PRL 35001420 mounting brackets support PRL modules with dimensions of 1.3W x 2.9H and lengths of 2.90", 3.90", 6.10", and 8.10".

PRL modules of other sizes are not supported directly, although PRL mounting brackets can be used with any PRL modules if appropriate holes are drilled in the base plate.
