The KL1412 complements the proven KL1404, KL1414, KL1408 and KL1418 digital input terminals with their type 3 specification. The current/voltage characteristics have been optimised for 2-wire sensors. The input current in low state is increased to a minimum value of 1.5 mA and therefore supports the majority of commercially available 2-wire sensors. A typical value for the energy-saving high current is 2.2 mA. The input complies with the EN 61131-2 type 3 standard and is compatible with type 1.
