Triconex MA2211-100 CIM Media Adapter

Product Description

The MA2211-100 is an isolated media adapter for Triconex Trident SIS communication interface modules (CIM). It performs bidirectional conversion between RS232 and RS422/RS485, enabling Trident CIM to connect to Modbus RTU multi-drop field networks. It is self-powered from RS232 signal lines, no external power supply required, and provides optical isolation to eliminate ground loop interference for reliable long-distance serial communication.

• Legacy Trident system spare replacement and communication retrofit
• Process safety interlock system serial protocol conversion

FAQ

Q: What is the difference between MA2211-100 and normal serial converter?
A: It is a dedicated adapter for Triconex Trident CIM, optimized for SIS safety communication timing and isolation requirements, not general-purpose commercial converters.

Q: Which system does it belong to?
A: It matches Triconex Trident SIS platform, works with Trident CIM communication modules.

Q: Is this unit discontinued?
A: Trident series is legacy SIS hardware, original production stopped, supplied as surplus, refurbished and tested spare parts only.

Q: Does it need external power supply?
A: Normally self-powered from RS232 signal lines; special long-bus or noisy environments may require external auxiliary power.
