FAQ
- Q: Can the DI80-N be used with sensors other than 3-wire PNP/NPN sensors?
- A: No, the DI80-N is specifically designed for use with eight 3-wire PNP/NPN sensors (IEC 61131, Type 3). Any other use is not recommended.
- Q: What should I do if a channel shows a fault indication?
- A: If a channel displays a fault indication such as wire breakage or short circuit, refer to the manual for troubleshooting steps or contact technical support.

For your safety
Intended use
The device is a piece of equipment from explosion protection category “increased safety” (IEC/EN 60079-7) and may only be used as part of the excom I/O system with the approved module carriers MT… (TÜV 21 ATEX 8643 X or IECEx TUR 21.0012X) in zone 2.
DANGER
These instructions do not provide any information on use in zone 2.
Danger to life due to misuse!
- Operation in zone 2: Observe the information on use in zone 2 without fail.
The 8-channel digital input module DI80-N serves for connection of eight
3-wire PNP/NPN sensors (IEC 61131, Type 3). The inputs are galvanically
isolated from each other.
Any other use is not in accordance with the intended use. Turck accepts no
liability for any resulting damage.
General safety instructions
- The device may only be mounted, installed, operated, configured and maintained by professionally trained personnel.
- The device meets the EMC requirements for industrial areas. When used in residential areas, take measures to prevent radio interference.
- Only combine devices that are suitable for joint use based on their technical data.
- Check the device for damage before mounting.
Product description
Device overview
See fig. 1: Device view, fig. 2: Dimensions.
Functions and operating modes
The sensors are powered by a reverse-polarity protected auxiliary energy
supply (24 V), The auxiliary energy is fed separately externally via the
connection terminals to channels 1…4 (group 1) and 5…8 (group 2).
Flutter monitoring detects and reports procedurally unusual signal patterns,
for example too frequent fluctuation of the input signal between “0” and “1.”
The occurrence of such signal patterns is an indication of faulty sensors or
process-related instabilities.
Installing And Connecting
Installing
Multiple devices can be mounted directly next to each other.
- Protect the mounting location from radiated heat, sudden temperature fluctuations, dust, dirt, humidity and other ambient influences.
- Insert the device into the designated position on the module rack so that it noticeably snaps into place.
Connecting
- When plugged into the module rack, the device is connected to the module rack’s internal power supply and data communication.
- Screw connection terminal blocks or terminal blocks with spring technology can be used to connect the field devices.
- Connect the field devices as shown in “Wiring diagram.”
Commissioning
- Switching on the power supply on the module rack immediately switches on the fitted device.
- As part of the commissioning process, the input behavior must be parameterized once via the fieldbus master, and the module slot must be configured.
Wiring diagram
Operating
The device can be fitted in or removed from the module rack during operation if a potentially explosive atmosphere is not present.
LEDs
Setting
The behavior of the inputs is parameterized via an associated configuration tool, FDT frame or web server, depending on the higher-level fieldbus system. The following parameters can be set for each channel:
- Short-circuit monitoring
- Wire-break monitoring
- Substitute value strategy
- Direction of current flow (PNP or NPN)
- Polarity
- Flutter time window
- Number of signal changes
- Activate or deactivate channel 1…8 individually
Repair
- The device must not be repaired by the user.
- The device must be decommissioned if it is faulty.
- Observe our return acceptance conditions when returning the device to Turck.
Disposal
- The device must be disposed of properly and does not belong in the domestic waste.
