Expansion modules for the KT-400

Connect expansion modules to the KT-400 controller to add outputs such as relays and open drain outputs, and inputs. Mixing up input and output expansion modules gives the ability to connect up to 256 inputs and 256 outputs for each KT-400 controller.

• KT-MOD-REL8: This is an 8-relay expansion module used as general relays or elevator control outputs. The module supports daisy chaining which can add up to 32 KT-MOD-REL8 modules for a total of 256 external relays for each KT-400 controller.
• KT-MOD-INP16: This is an input module that adds up to 16 zones to the KT-400 controller. The module supports daisy chaining; you can interconnect up to 15 KT-MOD-INP16 modules for a total of 240 external inputs for each KT-400. Adding the 16 onboard inputs of the KT-400 gives a total of 256 inputs for each KT-400.
• KT-MOD-OUT16: This is an open drain to 12 VDC 16-output module. You can use it for elevator access control (which may require additional hardware). The module supports daisy chaining; you can interconnect up to 16 KT-MOD-OUT16 modules for a total of 256 external outputs for each KT-400.
