Beckhoff KL1 Series User Manual

Product overview
KL1xxx 17Version: 1.0.0
2-channel digital input terminal 24V
DC
, type 3
The KL1402 and KL1412 supplement the proven KL1404, KL1414, KL1408 und KL1418 digital input
terminals with their type-3 specification. The current/voltage characteristics have been optimized 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.
