C - Compute and Compare Overall Current Draw
Calculate the total current draw for all door peripherals, all Hi-O interface devices, and all Hi-O enabled readers with the
following equation, adding terms as required.

total
For this example, the total current draw is shown.
I
@ +12VDC = 15mA + 300mA + 28mA + 70mA + 160mA* + 40mA* = 613mA
total
I
@ +24VDC = 15mA + 150mA + 38mA + 70mA + 160mA*+ 40mA* = 473mA

* Notes:
a. The EDM-M draws 40mA standby current.
b. The Hi-O iCLASS reader requires a +24VDC to +12VDC converter module (EDGE EVO Hi-O Voltage Module
Compare the required current draw (I
1) to select the EH400 power scheme. The CAN DC PWR Output represents the entire power output capacity of the
EH400.

Hi-O Networked Controller
(EH400)
In this example, the EH400 provides sufficient power when operating with +12/+24VDC auxiliary power supplies.
Directly connect the door peripherals identified in "Step 1 - Identify System Components" on page 2 to the I/O ports
of the EDGE EVO Hi-O Edge Door Module (EDM-M). Consult the EDM-M datasheet to determine the available current
capacity for the selected input power scheme of the EH400.
Ensure all door peripherals connected to the Strike/AUX relays and the Reader DC PWR Output or both do not exceed
1.2 Amps (AUX Input) or 400mA (PoE Input) combined. Alternatively, connect the door peripherals to the Strike/AUX
relays configured for Dry contact up to 2 Amps per relay.
