Description
The remote S900 I/O system can be installed in non-hazardous areas or directly in Zone 1 or Zone 2 hazardous area depending on the selected system variant. S900 I/O communicates with the control system level using the PROFIBUS DP standard. The I/O system can be installed directly in the field, therefore the costs for marshalling and wiring are reduced.
The system is sturdy, error-tolerant and easy to service. Integrated disconnection mechanisms allow replacement during operation, meaning that there is no need to interrupt the primary voltage in order to exchange the power supply units.
S900 I/O type S. For installation in hazardous area Zone 1. For connecting intrinsically safe field devices installed in Zone 2, Zone 1 or Zone 0.
AI950S 3KDE175521L9500 Temperature Input (TI4-Ex), supporting Pt100, Pt1000 and Ni100 in 2-/3-/4-technology. Thermocouples type B, E, J, K, L, N, R, S, T, U, mV. Isolated inputs channel by channel.
Applications
Liquefied Natural Gas (LNG) Plants: Used for temperature monitoring of cryogenic storage tanks and pipelines in Zone 1/2 hazardous environments.
Fine Chemical Plants: Used for high-precision temperature control in Zone 1 explosion-proof areas such as reactors, supporting multiple types of thermocouple connections.
Fertilizer Plants: Safely collect sensor data in processes with explosion hazards, such as ammonia synthesis or urea production.

Troubleshooting
Channel Alarms (Red Light/Status Bit):
Open Circuit/Short Circuit: The module monitors loop integrity in real time. If a sensor burns out, the system immediately receives a diagnostic message.
Measurement Overflow: Checks if the RTD is set with the correct wiring (e.g., actual 3 wires but software set to 4 wires).
Value Drift: Checks the thermocouple cold junction compensation setting. If using external compensation, ensure the compensation sensor is functioning correctly.
Confirms the notch filter is set to the field power frequency (50Hz/60Hz) to suppress interference.
Maintenance
Hot-swappable in Hazardous Zones: Supports live module replacement in Zone 1 hazardous areas without power outages or hot work permits (must comply with on-site safety regulations).
Configuration Flexibility (HCIR): Supports changing sensor types (e.g., changing a Type K thermocouple to a Pt100) via the control system without stopping system operation.
Base Compatibility: Must be installed on an S900 Type S (blue intrinsically safe) base.
FAQ
Q: What is the AI950S 3KDE175521L9500?
A: It is a Temperature Input Module.
Q: What is the difference between AI950S and AI950N?
A: AI950S is intrinsically safe, designed for Zone 1, and can connect to intrinsically safe sensors in Zone 0. AI950N is intended for non-explosion-proof safety areas and does not have any explosion-proof or intrinsic safety certification.
Q: Why is my 3-wire RTD reading inaccurate of AI950S 3KDE175521L9500?
A: Ensure that the physical wiring is secure and that the “3-wire” configuration is correctly selected in the software. If this setting is incorrect, the module cannot compensate for the lead wire resistance, leading to inaccurate measurements.
