Connecting Sensors, Switches, or Devices
The following describes how to wire sensors, switches or controls to the XML1000 inputs.
The RELAY is designed to switch currents (120VAC/2A, 24VDC/5A). In a
sense, the RELAY can act as a contact closure or switch for any external
device. The relay connections are labeled as Normally Open (NO), Common
(COM), and Normally Closed (NC). When wiring, connect your wires to the NO
and COM if you want the switched circuit to be CLOSED when the relay is
ACTIVATED. Connect your wires to NC and COM if you want the switched
circuit to be OPEN when the relay is ACTIVATED.
The DIGITAL INPUT interfaces are designed to connect to up to either dry
contact closures or voltage pulses. The interface provides two (6) wire inputs;
(4) switch inputs and (2) grounds (GND). Switches are connected across any of
the inputs (labeled with numbers 1-8). The grounds (labeled with GND) are used
as commons, and are where you connect the second switch wire. The reasons
for only (4) commons is because you can share the GND inputs between
switches the switches. The following is a wiring example:
The ANALOG INPUT interface has the ability to interface with any analog
sensor with the following voltage output ranges: 0-5 VDC; 0-30 VDC; 4-20mA.
The following is a sensor wiring example:
The ANALOG OUTPUT interface is designed to provide a variable voltage
output of 0-5VDC.
