Reference
– These signals are referenced to logic ground (COM).
Protection
– Each signal has a 30 volt transient voltage suppressor
between it and system ground.
Relay Output Points
Description of Signals
– NC, NO, and COM are the three connections to
a single pole, double throw relay. The following are the relay outputs:
Reference
– The relay is a dry contact relay rated at 1 A at 24 VDC/
VAC, 25 VA maximum.
Reader Power
Description of Signals
– 250 mA at 12 VDC is provided for each reader.
Protection
– There is a 750 mA PTC re-settable fuse.
Network Connection
RJ45 connector
– Use this connector to connect the S321-IP to the
