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 analog output for operation with voltage or current, since it is very important that the analog output of the display device is capable of reacting extremely quickly to changes, especially in fast-running processes.
