KT-400 Expansion Module 16-Output with SPI Cable Install Sheet
1. Introduction
The KT-MOD-OUT16 is a 16 zones output module. It can be
used for elevator access control (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
per KT-400. You can mix relays and outputs in the same SPI
group, up to 256 outputs.
Note 1: The KT-400 SPI port maximum current draw, when the
12V AUX terminals are not used, is 500 mA.
Note 2: External power supply (12 VDC, 2 Amps) is required
when the total current draw exceeds 500mA on the SPI Port.
Note 3: 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.
2. Specifications
Maximum Current draw: up to 750 mA per module
Connects to the KT-400 via the 6-pin SPI connector
16 outputs low current module, 5 to 24 VDC, 4 to 750 mA
Can be used for elevator access control or general output
Can be mixed with output module KT-MOD-REL8 in the
same SPI group
Operating Temperature: -10C to +55C
Maximum Humidity: 93%
IP Class 3X,IK Rating 04,(when mounted in Kantech cabinet)
3. Installing the KT-MOD-OUT16
3.1. Unpacking
The KT-MOD-OUT16 package includes the following parts:
•One (1) KT-MOD-OUT16 module, 14 cm x 8 cm (5.7 in x
3.25 in)
•One (1) SPI cable with 1 SPI connector, 41 cm (16 in)
•Four (4) plastic standoffs
•Two (2) installation sheets, English and French
3.2. Mounting
The KT-MOD-OUT16 can be installed inside a compatible cabinet
(KT-MOD-CAB or KT-400) or mounted in a dry and secure
location at less than 1 m (3 ft) from the KT-400.
Perform the following steps to mount the unit:
1. Press the four (4) plastic standoffs through the mounting
holes of the cabinet,
2. Secure the cabinet to the wall in the desired location. Use
appropriate wall anchors when securing the cabinet to
drywall, plaster, concrete, brick or other surfaces,
3. Press the module into the plastic standoffs to secure the
module to the cabinet.
Once the unit is mounted, wiring may be started.
3.3. Installation and Wiring
Before beginning to wire the unit, ensure that all power (AC
transformer and battery) is disconnected from the KT-400.
Perform the following steps to complete wiring:
1. Connect the 6-pin SPI connector to:
the KT-400 SPI port, or
the SPI OUT of the previous output module (KT-MOD-
REL8 and KT-MOD-OUT16 only), or
the SPI EXP of the 1st input module KT-MOD-INP16
connected to the KT-400 SPI port.
2. Connect the six SPI wires (blue (BLU), white (WHT), green
(GRN), yellow (YEL), black (BLK) and red (RED)) to the SPI
IN (TB1) terminals.
3. Connect the 6-pin SPI connector from the SPI OUT to the
next output module (KT-MOD-REL8 and KT-MOD-OUT16
only).
4. Complete all output wiring.
