1.5 Connectors & Indicators
Relay
The XW-210 has an internal high-current relay. Screw terminals are provided for the Common, Normally
Open, and Normally Closed contacts of the relay. The screw terminals are internally connected directly to
the relay with no internal fuse or other over-current protection. The relay contacts are isolated from all
other circuits.
Digital Input
The XW-210 has an optically-isolated digital input. The optically-isolated input provides electrical isolation
between the digital input and the low voltage control circuits of the XW-210. The input can be used as a
pulse counter and has a built-in debounce of 20ms.
1-Wire Sensor Bus
The XW-210 works with “1-wire” digital temperature and other Xytronix 1-wire sensors. The sensors are
available in several configurations, are interchangeable and require no calibration. The sensors require
three connections for communications and power (+5V, Gnd, Data). Control relays or trigger email
messages based upon temperature and other sensor values.
Power Supply
The XW-210 employs modern switch-mode power supply which works from 9 to 28VDC. With this type
of power supply the current draw decreases as the voltage increases. The power supply voltage (+Vin) is
monitored internally and can be logged.
