Analog Output - Voltage Mode (0–10
VDC)
10 VDC maximum output voltage
10 mA maximum output current
Requires an external load of 1,000 ohms
or more.
Note:
The AO operates in Voltage Mode
when connected to devices with
impedances greater than 1,000
ohms. Devices that drop below
1,000 ohms may not operate as
intended for Voltage Mode
applications.

(Outputs)
See Guideline B in
.
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 300 ohms
may not operate as intended for
Current Mode applications.
Same as (Analog) OUTn.
Analog Output Signal Common
for all
Analog OUT terminals.
Note:
All Analog OCOMn terminals
share a common, which is isolated
from all other commons.

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

Note:
Each Binary Output common
terminal (OCOMn) is isolated from
all other commons, including other
Binary Output commons.
