Description
The KT-MOD-REL8 is an 8-relay outputs expansion module used as general relays or elevator control outputs.
The module supports daisy-chaining which can add up to 32 KTMOD-REL8 modules for a total of 256 external relays per KT-400 controller. You can mix relays and outputs in the same SPI group, up to 256 outputs.
Data Sheet – KT-400 Controller
Notes
- The KT-400 SPI port maximum current draw, when the 12V AUX terminals are not used, is 500 mA.
- An external power supply (12 VDC, 2 Amps) is required when the total current draw exceeds 500mA on the SPI Port.
- There are already 4 relays available on the KT-400. Make sure to check the relays number assignments to prevent redundancy unless it has been planned on purpose.
