Analog Output - Current
Mode (4–20 mA)
Requires an external load
between 0–300 Ohms.
Note: The AO operates
in Current Mode when
connected to devices with
impedances less than 300
Ohms. Devices that exceed
Ohm may not operate as
intended for Current Mode
applications.
See Guideline B in Table
13.
OCOMn Analog Output Signal
Common for all Analog OUT
terminals
Note: All Analog OCOMn
terminals share a
common, which is isolated
from all other commons.
Same as (Analog) OUTn.
OUTn Binary Output - 24 VAC Triac
(External Power)
Connects OUTn to OCOMn
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.

Jumper
positioned to
External (EXT).
OCOMn Binary Output Common (for
OUTn terminal)
Note: Each Binary
Output common terminal
(OCOMn) is isolated
from all other commons,
including other Binary
Output commons.
See Guideline C in Table
13.
