The Kongsberg AL-100B/I8EX Analogue Input Node is an intrinsically safe (Ex ia) input module used in Kongsberg marine monitoring systems, especially tank gauging and cargo/ballast monitoring on tankers and gas carriers. It reads up to eight field sensors – such as PT100/PT1000 temperature sensors, pressure transducers and on/off switches – and passes the values over the system communication line.
SM MARINE SERVICE™ (https://www.smmarineservice.com/) supplies Kongsberg AL-100B/I8EX analogue input nodes (new and refurbished) and related Kongsberg automation spare parts to ships worldwide.
The AL-100B/I8EX is a distributed I/O node. Instead of running each sensor cable to a central cabinet, the node is installed close to the sensors and connects them locally. The label on the unit shows examples of sensor connection: 4-wired and 2-wired PT100/PT1000 temperature sensors, pressure transducers of the GT-250 series, and on/off switches. The node is powered and linked to the system through the X9 POWER and COMM terminals, which have IN and OUT pairs so several nodes can be connected in a chain.
Because the module is certified Ex ia IIC T4, it is suitable for intrinsically safe circuits connected to sensors in hazardous areas, when installed according to its certificate and the system documentation.

The AL-100B/I8EX is itself a single electronic module (a complete PCB assembly inside a protective cover). Kongsberg has not published a public parts list for its internal boards, and no internal PCB number is visible in the supplied photographs. The known numbers are:
The complete module: 8-channel analogue input electronics, signal conditioning for PT100/PT1000 and pressure transducers, and communication to the system. Part number 7212-235.002 is taken from market listings (Not printed on the photographed unit).
Code listed together with the AL-100B/I8EX in a market listing. Its exact meaning is Not verified.
Pluggable 4-pole screw terminal blocks for the eight sensor channels.
POWER IN/OUT and COMM IN/OUT terminals (201–204) for supply and data link, with pass-through to the next node.
Tip: If your node shows a different part number or revision on its label, send us a photo – SM MARINE SERVICE™ will check compatibility.
Use of AL-100B/I8EX with GL-100 and GLK-100A is based on market listings and the sensor types on the label; please confirm your exact system with us.
Nameplate: Kongsberg Analogue input node, Type AL-100B/I8EX, Ex ia IIC T4, Nemko 12.7035X, Sn.:4005
Safety note: This is an intrinsically safe (Ex ia) device. Work only according to the hazardous-area rules on board, the certificate conditions and the maker's documentation. Do not connect non-certified equipment to the Ex circuits, and do not modify the module. Isolate power before replacing the node and use qualified personnel.
Alarm texts for sensor and node faults are shown on the system's operator station and are documented in the manual of the installed Kongsberg system. We do not list undocumented alarm codes.

Kongsberg tank gauging and monitoring systems are installed on many tankers and gas carriers. When one node fails, replacing only that AL-100B/I8EX module restores the measurements quickly, without changing sensors, cables or the whole system.
1. What is the Kongsberg AL-100B/I8EX?
It is an 8-channel intrinsically safe analogue input node for Kongsberg monitoring and tank gauging systems.
2. What is the part number of AL-100B/I8EX?
Market listings show part number 7212-235.002.
3. Is AL-100B/I8EX the same as AL-100B/18EX?
Yes – "18EX" is a common misreading of "I8EX" (I = input, 8 = eight channels, EX = intrinsically safe).
4. Which sensors can be connected?
The label shows PT100/PT1000 (4-wire and 2-wire), GT-250 series pressure transducers and on/off switches.
5. What is the Ex certification?
Ex ia IIC T4, certificate Nemko 12.7035X.
6. Are there internal PCB numbers?
No internal PCB number is visible in our photos and none is published. The module is normally replaced as a complete unit.
7. Can AL-100A/I8EX be replaced by AL-100B/I8EX?
Possibly, but this is Not verified. Please send your label photo so we can check.
8. Which unit powers the node?
In Kongsberg systems the AL-100B/RPEX Power and Repeater Unit is used for the Ex node line; confirm against your system drawings.
9. Do you supply GT-250 pressure transducers?
Please send us the transducer model – we source Kongsberg sensors on request.
10. Do you ship worldwide?
Yes, SM MARINE SERVICE™ ships worldwide from Bangladesh and China.
