Electrical
Power Supply
● 20 - 29 V DC
● 1Vpp ripple
Power Consumption
116 mA @ 24V DC:
No relays activated, and no inputs connected to MFI.
183 mA @ 24V DC:
All relays active, inputs double balanced.
193 mA @ 24V DC:
All relays active, inputs current loop.
Inputs
Up to 8 Monitored inputs are used for Door position sensor inputs
and REX inputs with MFI configured in Door Controller mode.
These 8 inputs can be used as general input points with MFI
configured in input-output controller mode.
Relay outputs
8 relay outputs,
max 30 V DC , 2A
Open Collector Outputs
3 Open Collector Outputs, Max load 0.5A
Reader Connections
Supports maximum up to 8 OSDP Readers with OSDP V1 and OSDP
V2 encryption.
Power output
12V DC, max 500mA protected by firmware controlled e-fuse
Can be used to connect readers or any other load, but restricted to
500mA overall current output.
24V DC, max 1500mA protected by firmware controlled e-fuse
Can be used to connect readers or any other load, but restricted to
1500mA overall current output.
24V DC, max current restricted by MFI power supply capability
Can be used for powering door locks. However, it is not suggested
for powering readers as there is no firmware controlled fuse to
detect over current draw.
