BO-#
Binary Output - 24 VAC Triac
(External Power)
Connects BO-# to BO-C# when
activated.
External Power Source:
30 VAC maximum output voltage.
0.5 A maximum output current.
1.3 A at 25% duty cycle.
Maximum 6 cycles/hour with
M9220-BGx-3.
40 mA minimum load current.
BINARY
(outputs)
BO-C#
Binary Output Common (for
BO-# terminal)
Note: Each Binary Output
common terminal is
isolated from all other
commons, including other
Binary Output commons.
See Guideline C in Table 7.
Analog Output - Voltage Mode
(0–10 VDC)
10 VDC maximum output
voltage.
10 mA maximum output current.
Requires an external load of 1000
Ohms or more.
See Guideline A in Table 7.
CO-#
Binary Output 24 VAC Triac
(External Power Source only)
Connects CO-# to CO-C# when
activated.
External Power Source:
30 VAC maximum voltage to
load.
0.5 A maximum output current.
1.3 A at 25% duty cycle.
Maximum 6 cycles/hour with
M9220-BGx-3.
40 mA minimum load current.
See Guideline C in Table 7.
CONFIGURABLE
(Outputs)
CO-C#
Analog Output Signal
Common: All Configurable
Outputs defined as Analog
Outputs share a common,
which is isolated from all other
commons except the Binary
Input common.
Binary Output Signal Common:
All Configurable Outputs defined
as Binary Outputs are isolated
from all other commons,
including other Configurable
Output commons.
Same as (Configurable) CO-#.
The following table defines cable length guidelines for the various wire sizes that can be used for input and output
wiring.
