FXVMA Installation Instructions
4
Active Sensor Connection
The UI accepts a 0-10 VDC input signal from an active
sensor. The UI has an internal 75k ohm pulldown. The
active sensor can be powered externally; alternatively,
the FXVMA provides 15 VDC, 35 mA power to power
the sensor locally. See Figure 4 and Figure 5.
Dry Contact Switch Connection
The UI accepts a dry contact switch input with a 1 s
minimum pulse width (0.5 Hz at 50% duty cycle). The
UI has an internal 12 V, 15k ohm pullup.
Binary Output Wiring Details
The FXVMA features three field-connectable binary
outputs. These binary outputs are 24 VAC, 0.5 A triacs
that you can configure to control on/off devices (such
as fans, 2-position valves, and heating elements) or
incremental actuators.
Use Figure 7, Figure 8, and Figure 9 to make the
appropriate wiring connections to the Binary Outputs.
Refer to the configured FXVMA application
documentation for actual Binary Outputs used.
