Technical specifications
The following table lists the technical specifications of the KT-MOD-IO16.
Dimensions (H x W x D) 31.5 x 146 x 82.6 mm (1.25 x 5.75 x 3.25 in.)
Weight 118 g (1/4 lb)
Operating temperature 2°C to 40°C (35°F to 104°F)
Operating humidity 0 to 95 % non-condensing
Input voltage 9.5 VDC to 15 VDC
Current consumption Typical: 500 mA at 12 VDC (25 mA for each
terminal)
Max: 1.6 A at 12 VDC (45 mA for each terminal)
RS-485 LED indicators 2 LEDs for the RS-485 communication (RX, TX)
Vital LED indicator LED indicating the module status.
Inputs/Outputs 16 I/Os: configurable in lots of 4.
Inputs I/Os that are configured as inputs support
normally closed (NC) and normally open (NO)
contacts. Inputs support no end-of-line, single
end-of-line, and double end-of-line zone loops.
Outputs I/Os that are configured as outputs (open-drain
outputs) can sink up to 750 mA each. Each
module can sink a maximum of 4 A.
Input/Output LED
indicators 16 LEDs for the I/O status.
Aux power outputs 4 terminals wired together to supply up to 1.5 A
out of the input power. These outputs are
supervised and current limited.
SPI port I/Os #9 to #12 that are configured as SPI ports
can support a daisy-chained SPI bus that consists
of 8 KT-MOD-REL8 modules. Each module can
provide 8 Form C relay outputs.
Terminal blocks Removable type, color coded, supports 12 to 30
AWG cables.
