Digital Outputs
The MX16160 module has sixteen digital
outputs that can be connected to a maximum
of 24 Volts AC/DC. Each output is a dry
contact (rated at 3A, 24VAC maximum) that
can be configured as normally open or
normally closed, according to the jumper
setting.
Be sure the MX16160’s power is off before
wiring any inputs or outputs. Connect the
output wiring to the screw terminals on the
module as shown in Figure 5.
NOTE
Do not power pilot relays from the
same transformer that powers the MX16160.
To verify each output’s operation, lock the
output to a known condition using the
Function Block’s Parameter page, then make
sure the equipment actually operates as
specified.
Each digital output can be placed in Manual
or Auto mode by setting the HOA switches
(see Figure 1 on page 2 for the switches’
location). Table 2 shows the status of the
digital output based on the output’s
configuration and the HOA switch position.
