Hardware Specifications
Door lock output (DR LCK)
Switched Ground enables the Ground (powering the lock), or
disables ground (releasing power from the lock).
The MPA1C1 can source up to 500 mA of current through its
12V Out.
Connect the positive side of the lock to the 12V Out and Ground
wire of the lock to the SW GND of the MPA1C1.
Relay Contacts (AUX OUT)
1 Form-C SPDT relay, 2A (at dry contact) @ 30VDC ( 0.6 Power
Factor) is configured as Normally Open and Normally Closed
outputs.
Reader Interface (OSDP READER)
• Reader Power: See Power outputs section: Maximum output
current for reader(s) is 500mA @ 12VDC nominal.
• Reader Data Communication: Single half-duplex RS485
OSDP V2.1.8 with multi-drop support at 9600 Baud.
Power input (PWR IN)
An External DC power supply can be connected PWR IN: +12V IN
and GND. The input voltage is specified at 10 to 15VDC (12VDC
Nominal). Maximum input current is 900mA @12VDC.
Power outputs(+12V OUT)
The following power rating are valid when the MPA1C1 is pow-
ered by an external power supply:
• There are two 12VDC power outputs. One at DR LCK and one
at OSDP READER. The output voltage to the device connected
to these outputs is specified at 9 to 15VDC (12VDC Nominal).
