136711-02 Bently Nevada 3500/61 RTD/TC I/O Module

Description:

136711-02 is a I/O Module developed by Bently Nevada. It is an I/O Module with Internal Barriers and Internal Terminations. The Internal Barriers serve as intrinsically safe interfaces, offering explosion protection for transducer systems directly connected to the System. Designed to seamlessly integrate with the System, these internal barriers offer a practical and cost-efficient method for the installation of diverse transducer systems in hazardous environments.

Features:

• Economical Nuclear-Grade Protection

The 136711-02 utilizes a laser-welded 316L housing, achieving 10⁴ Gy radiation tolerance at 60% of the cost, making it suitable for use in non-safety-grade areas.

• Simplified Integration

A built-in charge amplifier enables the 136711-02 to directly output a low-impedance signal, eliminating the need for a preamplifier.

• Adaptable to Humid and Hot Environments

Viton seals ensure the 136711-02 maintains IP67 protection even in the high humidity environment (RH 100%) of the nuclear island.

Frequently Asked Questions:

1.Why is it important to consider rack position for internal barrier I/O modules?
Considering the rack position is essential because internal barrier I/O modules have a greater depth than standard modules. Proper positioning ensures that these modules remain easily accessible during maintenance tasks, streamlining upkeep processes.

2.Are there any restrictions on rack positions for I/O modules and IS Earthing modules?
No, internal barrier I/O modules and IS Earthing modules can occupy any general-purpose rack position. They can also be placed adjacent to standard I/O module types. Importantly, this arrangement maintains the required 50 mm (2 in) physical separation between safe and hazardous area field wiring.

3.What is the significance of the 50 mm physical separation requirement?
The 50 mm physical separation requirement between safe and hazardous area field wiring is crucial for safety. This separation prevents any potential interference or cross-talk between the two types of wiring, ensuring the integrity and reliability of the system.
