DAT-30f-RFM-field-termination-and-barrier-modules

Product catalog summary

Overview: The document provides technical details about the RFM series Field Termination and Intrinsic Safety Barrier Modules, designed for use with PSM ict 1000 smart hydrostatic level transmitters. These modules facilitate network connections and ensure compliance with ATEX Intrinsic Safety standards.

Key Features:

Modular system that reduces the cost of power, signal, and data wiring loops.
Available in lightweight aluminium for below deck or painted steel for above deck mounting.

Installation and Configuration:

RFM series simplifies the installation of ict 1000 transmitters, offering configurations from simple termination boxes to fully approved barrier systems for hazardous areas.
Housings are IP67 rated, with cable entry via 6 x M20 glands and vented through waterproof sintered vent plugs.

RFM-1 & RFM-4 Modules:

Provide termination points for power and digital signal cabling, allowing for "pass-through" connections.
Enable digital multi-drop communication, reducing the need for extensive cabling compared to conventional 4-20mA loops.
Can be used in hazardous areas when combined with RFM-ISR modules.

RFM-ISR Module:

Offers intrinsically safe power and Modbus data transmission using zener barriers.
Supports power supplies between 15 to 35V DC and protects up to 105 ict 1000 transmitters.

Benefits of Using RFM & RFM-ISR Modules:

Simplifies installation by replacing multiple power and analogue signal loops with a single cable.
Reduces build costs by eliminating the need for copper cables and junction boxes.
Facilitates easy commissioning with accessible transmitter configuration and diagnostics.
Decreases weight, enhancing ship operational efficiency.

Application Example: The document compares a multi-tank installation using analogue versus Modbus digital communications, highlighting the efficiency and cost-effectiveness of the latter.
