Analog Output - Voltage Mode (0-10 VDC)
10 VDC maximum output voltage
10 mA maximum output current
Requires an external load of 1,000 ohm or more.
Note:
The AO operates in Voltage Mode when connected
to devices with impedances greater than 1,000
ohm. Devices that drop below 1,000 ohm may not
operate as intended for Voltage Mode applications.
OUTn
Universal
(Outputs)
See Guideline B in
Table 3
.
Analog Output - Current Mode (4-20 mA)
Requires an external load between 0-300 ohm.
Note:
The AO operates in Current Mode when connected
to devices with impedances less than 300 ohm.
Devices that exceed 300 ohm may not operate as
intended for Current Mode applications.
See Guideline B in
Table 3
.
Binary Output Mode - 24 VAC/DC Field-effect Transistor
(FET)
Connects OUT to OCOM when activated.
30 V AC/DC maximum output voltage
0.5 A maximum output current
40 mA minimum load current (hold current)
Same as OUT
Universal Output (UO) Common
Isolated from all other terminal commons, including other
UO commons.
