8-variable Profibus PA Remote Indicator

The IR303 receives up to 8 variables (float + status) via cyclical communication with the PROFIBUS DP class 1 Master and enables them on the LCD display. It works with any PROFIBUS DP mater and is ideal for applications with the TT383, 8-channel Profibus-PA temperature transmitter or any other Profibus equipment.




Digital only. PROFIBUS PA, 31.25 Kbits/s voltage mode, according to IEC 61158-2.

Current Consumption

12 mA from PROFIBUS PA network.

Function Blocks

8 AO output blocks that receive the 8 variables+status via SetPoint (SP) that will be displayed on the LCD. On LCD display the mnemonics must be configured up to 5 characters.

IR303 applied on devices at difficult-access locations

In some situations, the monitoring process by the user is hampered by the difficult access to the device.
The IR303 increases the user´s visibility, making the monitored variables easy to access.
