Quotation
Downloads

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.

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.

Turn on Time

Approximately 10 seconds.

Humidity Limits

0 to 100% RH.

IR303 applied on devices at difficult-access locations

 

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