M4x Interface Modules
The Raven M4x products offer the flexibility you need to create a solution to your application.
Mix and match any of the following modules:
476-777, 1-network port and 1 4-wire Analog interface VoIP Interface
This module has an Ethernet port/VoIP interface supporting Unicast, Multicast, ROIP & SIP and a 2 or 4-Wire Analog VF/VOX Audio interface (input can be 600 ohm or high impedance and output is always 600 ohm). The most flexible module available.
476-150, 2-port 4-wire Analog Interface
This module has two channels in and out, can do DTMF detection, VOX detection with relay output, voice delay up to 1 second on each channel, M-lead (PTT) relay outputs and E-Lead (COR) inputs. The input and output are 600 ohm.
476-151, 2 port 4-wire Analog Interface
This module can do DTMF detection, VOX detection with relay output, voice delay up to 1 second on each channel, M-lead (PTT) relay outputs and E-Lead (COR) inputs. The input can be 600 ohm or high impedance, and output is always 600 ohm. This module is designed for very low frequency signals.
476-153, 2 port 4/2-wire Analog Interface
This module is similar to a 476-151 module with a 2-wire option. It also includes the added feature of automatic gain control.
475-155, Conference Interface
This module is a conference bridge for large multi-blade systems that need conferencing capabilities. This is used in our MediLink product.
476-170, Telephone Interface
Two channels for 2-wire and 4-wire telephones, restricted to two modules per single blade.
476-175, PSTN (or SNI) Interface
Two channels for connecting to 2-wire circuits with telephone battery voltage applied.
476-180, I/O Interface
This module has the capability of monitoring or control of up to 16 control points. Each line can be programmed as either an input or an output.
If you don't see what you need, please ask us about it. However unique or complex your requirement, Raven has either already accomplished the task or will apply our flexibility and capability to do so, quickly and competitively.
Raven is an engineering factory focused on providing specialized communications.
