The IA640 was discontinued on 30.09.2023.
In certain applications, the touchMATRIX® devices DX350 or IX350 can be used as a substitute.
The IA640 double-position indicator with the 15 mm high, 6-digit LED display has the same range of functions and the same features as the IA340 version. Thanks to the larger design, the switching function for the 4 programmable limit values in variant ID640 can be supplemented by 4 additional relays (potential-free changeover contacts).
As a further feature, the IA640 has a fast and freely scalable analogue output for operation with voltage or current, since the analogue output of the display device must be capable of reacting extremely quickly to changes, especially in fast-running processes.
