The 136188-02 is one component of the 3500/92 Communication Gateway system:
| Component | Function |
|---|---|
| 136180-01 Main Board | The "brain" of the gateway, handling protocol conversion and data processing |
| 136188-02 I/O Module | The physical interface, providing Ethernet and serial connectors, plus digital I/O terminals |
| 3500/92 Gateway | Complete system enabling full 3500 rack integration with third-party systems |
Critical Note: The 136188-02 is a passive terminal board that requires the 136180-01 main board to function. These two components must be used together to complete the 3500/92 Communication Gateway system .
The 3500/92 Communication Gateway is widely deployed across critical machinery protection applications :
| Industry | Application |
|---|---|
| Oil & Gas | Connecting compressor vibration data from 3500 racks to central DCS systems in refineries and pipeline stations |
| Power Generation | Integrating turbine monitoring data into plant PLC control systems for interlocking protection via Modbus serial links |
| Chemical Processing | Aggregating data from multiple 3500 racks across a facility to remote diagnostic centers via Ethernet |
