Features: Combines the functions of a 3500/20 framework interface module (RIM) and a communications processor such as TDXnet. Can be used with M-Series monitors such as the 3500/40M, 3500/42M, etc., to continuously acquire steady-state and transient waveform data and transmit the data to the host computer software via Ethernet.
Port type: 10/100 Base T Ethernet I/O module with RJ-45 interface for 10Base-T/100Base-TX Ethernet cables, cable length up to 100m; It also has a 100 Base FX Ethernet input/output module, MT - RJ fiber optic connector for 100Base - FX cables, and can connect up to 400 meters of multimode fiber optic cables.
Status indication: The operating status of the module is indicated by means of a light-emitting diode, and the OK status of the frame is indicated by an OK relay.
Configuration: It has a configuration port and uses the RS-232 protocol to configure or retrieve machine data.
Slot location: TDI occupies only one slot in the frame, usually in the first slot (immediately next to the power module).
Special Feature: For Triple Module Redundancy (TMR) applications, the 3500 system requires TDI in the form of TMR. TMR TDI has a "Monitor Channel Comparison Function" that continuously compares the outputs of three redundant monitors, and if an anomaly is detected, an error indication is sent to the monitor, and an event is added to the system event list.
