HID has two lines of Edge controllers: EVO (newer) and Legacy. The newer line of controllers can take an optional 2nd reader and have enhanced power efficiency (12 to 24 VDC), therefore, can support 12 V or 24 V locks.
In the following series of tables, we compare the characteristics of the EVO
controllers to their Legacy counterparts. For more information, refer to HID
documentation.
Edge platform differences between EVO and Legacy
| Characteristics | EVO | Legacy |
|---|---|---|
| Flash memory | 128 MB | 8 MB |
| Maximum cardholder capacity | 125,000 | 44,000 |
| Offline cardholder capacity with Security Center1 | 65,0002 | 22,0002 |
| Power over Ethernet (PoE) standard | 802.3af | 802.3af |
| RTC backup | Super-cap (2-5 days) No replacement required |
Battery (3-5 days) Requires replacement |
| Tamper | Optical and external switch | Mechanical and external switch |
| Door communication | Discrete I/O, Wiegand, Hi-O | Discrete I/O, Wiegand |
| Mounting holes and wiring termination | US Single-Gang, EU/ASIA 60 mm | US Single-Gang |
| Standby condition currrent | 85 – 180 mA | 1 A |
| Maximum current | 1.5 A | 1.5 A |
| Maximum combined output rating | 1.2 A | 700 mA |
| Operating temperature range | 32 ° – 120 ° F ( 0 ° – 49 ° C) | 32 ° – 120 ° F ( 0 ° – 49 ° C) |
| Humidity | 5% to 85% non-condensing | 5% to 85% non-condensing |
1 In Security Center, a cardholder can have multiple credentials. A cardholder with two credentials is counted as two by HID.
2 With Security Center, the unit's cardholder capacity is lower than its maximum cardholder capacity. This is partly because extra memory is used as cache to allow unit synchronization to be performed without affecting normal operation.
