Honeywell Network Hardware NETAXS-123 Benutzerhandbuch

The specifications in this section apply to both the Standard Enclosure and Compact Enclosure panels.

Maximum of six Form-C SPDT relays, 3A (at dry contact) or 0.5A (at self-whetted) @ 30VDC (PTC 
limited in the self-whetted mode). The Form-C SPDT relays are configured as Normally Open or 
Normally Closed outputs only. Normally Open and Normally Closed contacts cannot be used 
simultaneously.

• Reader Power: 12VDC nominal with 500mA maximum for each reader port.
• Reader LED Output: Open collector driver capable of sinking up to 8mA.
• Reader Tamper: Supervised or non-supervised input.
• Reader Data Input: TTL compatible inputs.

Use the following guidelines unless you are using Power Over Ethernet (PoE):

• Maximum current per reader port for any of the three reader outputs is 500mA.
• Maximum current for any of the six relay outputs on the Songchuan 892N-1CH-1F-V is 3A at 

dry contact, or 0.5A at self-whetted.

• Maximum battery charge current for the battery wired in series is 250mA.
• External power on C-TB9 is limited to 1.5A @ 12VDC.

If you are using the NetAXS-123 Standard Enclosure and powering the panel with PoE (Power over 
Ethernet), you must comply with these specifications for proper operation: 

• A NetAXS-123 panel powered by PoE is 802.3af compliant, providing a maximum of 15.4W 

of input power to the panel. This input power is split between on-board power consumption and 
external load consumption.  A maximum current capacity of 450 mA @ 12VDC is available for 
all external devices combined.

•   Two readers per door can still be supported as long as the total current is within the 

external load capacity stated above.

•   You can either find the devices’ power consumption amounts by referring to the 

products’ documentation or by using a current meter.
