Design and application
PS1A-LCK module is dedicated to provide power supply for the second door if built-in power supply unit of
the MC16 controller or MCX402DR expander is sufficient for only single door. The module is supplied with
18VAC and it offers 13.8VDC at LCK and TML outputs. The LCK (1.0A) output is dedicated to supply door
lock and it can be triggered with LCKEN input. Optionally it can be triggered all the time and used to supply
door related devices e.g. alarm signalling, door bell. The TML (0.2A) output is dedicated to supply readers
and is triggered all the time. PS1A-LCK can be connected to backup battery in order to offer emergency
supply for door. The shortage of 18VAC power supply is signalled with ACL transistor (open collector)
output. All PS1A-LCK outputs are protected against overload. PS1A-LCK is offered individually as electronic
module or as a component of MCX402-2-KIT.

Power supply and backup battery
PS1A-LCK module is supplied through AC terminals and red LED indicator is located at the AC+ terminal to
signal the voltage at the input. The module can be supplied from own 18VAC/20VA transformer or the same
transformer which supplies MC16 controller or MCX402DR expander. In such case the power of transformer
must be sufficient to ensure supply to all devices. Positive pole of the battery connected to the
controller/expander must be also connected to module BAT+ terminal. Do not connect battery negative pole
to the module. PS1A-LCK ground must be connected with controller/expander ground.

LCK output and LCKEN input
LCK output is dedicated to supply door lock. The output can be triggered with LCKEN input which on the
other hand can be triggered by transistor or relay output with minimal rating 15V/5mA at the
controller/expander. When LCKEN is shorted to ground then LCK is triggered. If the input is shorted to
ground constantly then LCK output could be used to supply door related devices such as alarm signalling,
door bell, etc. The terminal LCK+ is protected with 1.0A electronic fuse. The terminal LCK- is internally
shorted to ground. Green LED indicator is located at the LCK+ terminal to signal voltage at the output.
TML power output
TML power supply output is dedicated to supply readers at doors. The terminal TML+ is protected with 0.2A
electronic fuse . The terminal TML- is internally shorted to ground. Green LED indicator is located at the
TML+ terminal to signal voltage at the output.
ACL signalling output
ACL output is triggered in case of 18VAC power supply shortage and it can switch up to 40mA current at
15V. MC16 controller and MCX402DR expander monitor their power supply thus ACL output is used only if
PS1A-CLK is supplied from its own transformer.

Door control and connection to controller/expander
The module offers 13.8VDC power supply to readers and door lock when supplied from 18VAC transformer.
LCK output can be controlled in two alternative ways according to fig. 4. Transistor output or relay can be
used to control the lock.

Installation
Enclosure with DIN rail is recommended for installation of PS1A-LCK power module. All electric connections
must be done without voltage on wires/terminals and with power supply disconnected. Optionally, DIN rail
mounting clips can be removed and the module can be installed on flat surface. It is recommended to install
the module in the same enclosure as controller/expander.
