1.0 General Description
The Oldham WX16 Sixteen Channel Controller is designed to display and control
alarm event switching for up to sixteen sensor data points. It may also be set as an
eight channel controller for applications needing fewer inputs. Alarm features such as
ON and OFF delays, Alarm Acknowledge , and a dedicated horn relay make the WX16
well suited for many multi-point monitoring applications. Data may be input to the
WX16 by optional analog inputs or the standard ModBus
®
RTU master RS-485 port. A
ModBus RTU slave RS-485 port is also standard for sending data to PC’s, PLC’s,
DCS’s or even other WX16 Controllers. Options such as analog I/O and discrete relays
for each alarm are easily added to the addressable I
2
C bus. Option boards have 8
channels and therefore require 2 boards for 16 channel applications.
In addition to traditional analog and serial methods of providing monitored values, the
WX16 is also capable of sending and receiving wireless data as described in section 7
of this manual.
A 240 x 128 pixel graphic LCD readout displays monitored data as bar graphs, trends
and engineering units. System configuration is through user friendly menus and all
configuration data is retained in non-volatile memory during power interruptions. The
WX16 front panel is shown below in Figure 1.0 displaying the 8 channel bar graph
screen. Additional data screens are shown in Figure 2.0.
