1RU interface module frame with internal PSU, holds 1 or 2 interface modules. The IMF-102 interface frame combines an internal power supply, connection for a second redundant supply, a rear input/output connector panel and slots for two modular interfaces all in a 1RU chassis. The compact frame offers a practical way to add two interfaces to an Eclipse Omega, Median or PiCo digital intercom frame. PSU-101 can be added for power supply redundancy. It does not power the Party Lines attached to CCI-22 modules. These require Encore Master Station PSUs such as the PK-7, PS-702 or MS-702. IMF-102 frame does not include interface modules.
