Specifications

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 N. For installation in safe (= non-hazardous) area.

AI950N 3KDE175523L9500 Temperature Input (TI4), supporting Pt100, Pt1000 and Ni100 in 2-/3-/4-technology. Thermocouples B, E, J, K, L, N, R, S, T, U, mV. Isolated inputs channel by channel.

Applications

Heating plants/heat supply plants: Used for large-area boiler temperature monitoring and multi-point temperature measurement in heating networks.

Food processing plants: Used for precise temperature control on non-explosion-proof sterilization, baking, or refrigeration production lines.

Cement plants/brick kilns: Used to monitor high-temperature sensor signals in non-flammable areas of rotary kilns or coolers.

Paper mills: Monitors the temperature of drying drums and fluctuations in process circulating water temperature.

Wastewater treatment plants: Aggregates various water temperature monitoring points in the control room, utilizing its multi-channel characteristics to simplify wiring.

Troubleshooting

Sensor Open Circuit/Short Circuit Detection: The module automatically monitors each channel. If a sensor is damaged or a cable is broken, the corresponding channel status bit will report an error and trigger a system alarm.

Excessive Reading Deviation:

Check Wiring: For RTDs, confirm that the correct compensation method (3-wire or 4-wire) has been selected.

Cold Junction Compensation: For TCs, confirm that the cold junction compensation setting matches the field terminal unit (MTU) type.

50/60Hz Interference: Confirm in the configuration software that the notch filter setting is consistent with the field power frequency to eliminate common-mode interference.

Maintenance

Hot Swap: Supports module replacement during system operation without affecting the operation of the other 8 modules on the rack.

In-Run Configuration (HCIR): Supports changing the sensor type or range of a channel via DCS software without stopping the machine.

Base Matching: Must be installed on an S900 Type N (typically dark gray) base.

FAQ

Q: What is the AI950N 3KDE175523L9500?
A: It is a Temperature Input Module.

Q: What is the difference between AI950N and AI950S?
A: AI950N is designed for non-explosion-proof safety zones and does not have intrinsically safe certification. AI950S is intrinsically safe (Ex i) certified, suitable for installation in Zone 1, and can connect to intrinsically safe sensors in Zone 0/1.

Q: Does AI950N 3KDE175523L9500 support 4-wire RTD?
A: Yes. All 8 channels of the AI950N can be flexibly configured for 2-, 3-, or 4-wire RTD inputs, providing versatile measurement options.
