Description
Triconex 4119A Enhanced Intelligent Communication Module (EICM)
Continuing the safety system hardware sequence, 4119A specifies the Enhanced Intelligent Communication Module (EICM) manufactured by Triconex (Schneider Electric) for the Tricon Triple Modular Redundancy (TMR) safety system.
Key Specifications & Overview
-
Manufacturer: Triconex (Schneider Electric)
-
Product Type: Enhanced Intelligent Communication Module (EICM)
-
System Compatibility: Tricon TMR Safety Systems
-
Key Distinction (vs. Base 4119): The “A” variant provides enhanced 500 VDC port isolation across its communication channels to protect against severe electrical interference and ground loops in harsh industrial plant environments.
Communication Interfaces & Ports
The module features multiple concurrent communication channels:
-
Serial Ports (4 Total): Configurable independently as RS-232, RS-422, or RS-485. Supports point-to-point connections or multi-drop network configurations.
-
Parallel Port (1 Total): Centronics parallel interface with electrical isolation, traditionally utilized for direct alarm/event printer logging.
Protocols & Applications
-
Supported Protocols: Modbus (RTU/ASCII as either Master or Slave) and TriStation 1131 (engineering/configuration software protocol).
-
System Role: Allows the Tricon safety controller to securely interface with external supervisory systems (DCS, SCADA, HMIs), third-party Modbus devices, engineering terminals, and historical data printers without compromising the core integrity of the safety loops.
4119A
Product Overview
4119A is the Enhanced Intelligent Communication Module (EICM) manufactured by Triconex (Schneider Electric) for classic Tricon TMR safety instrumented system racks.
It acts as a serial communication gateway between the Tricon safety rack and external systems. The module collects vibration, temperature, interlock status and alarm data from internal monitoring boards, and exchanges information with DCS, SCADA, host workstations and printers via multi-channel serial interfaces. It supports Modbus RTU/ASCII and Triconex proprietary protocols, realizing data integration between turbomachinery protection hardware and plant control systems.
