Step 3 - Analyze Power Requirements
A - Door Peripheral Operational Currents
For the door peripherals identified in “Step 1 - Identify System Components” on page 2, consult the vendor data
sheets to determine the operational current draw. Typical operational current draw is provided below.
Note: See individual peripheral data sheets for actual operational current draw.
Device Conditions Typical Operational Current

Consult HID datasheets for Hi-O enabled interface devices.
B - Match I/O Requirements to the Hi-O Interface Device
For the door peripherals identified in “Step 1 - Identify System Components” on page 2, the system requires
connection to a Hi-O interface device. In this example, the EDGE EVO Hi-O Edge Door Module (EDM-M) provides
general purpose I/O connectivity.
The Hi-O iCLASS reader does not require connection to the EDM-M and derives power and data connectivity from the
Hi-O CANbus directly.

The combined current requirement for the four door peripherals identified in “Step 1 - Identify System Components” on
page 2 is 413mA @ +12VDC,
or 273mA @ +24VDC.
The EDM-M provides sufficient power when the door peripherals are connected to the Strike/AUX relays configured for
unregulated output at +12VDC/+24VDC. Alternatively, connect the door peripherals to the Strike/AUX relays configured
for Dry contact.
The Hi-O iCLASS reader does not require connection to the EDM-M and derives power and data connectivity from the
Hi-O CANbus directly.
