See Guideline C in Table 4.
Analog Output - Voltage Mode (0–10 VDC)
10 VDC maximum output voltage
10 mA maximum output current
Required an external load of 1,000 ohm or more.
Note: The Analog Output (AO) operates in the 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
ANALOG
(Outputs)
Analog Output - Current Mode (4–20 mA)
Requires and external load between 0 and 300 ohm.
Note: The Analog Output (AO) operates in the Current
Mode when connected to devices with impedances less
than 300 ohm. Devices that exceed below 300 ohm may
not operate as intended for Current Mode applications.
Analog Output Signal Common for all Analog OUT
terminals.
Note: All Analog Output Common terminals (OCOMn) share
a common, which is isolated from all other commons.
OCOMn
See Guideline C in Table 4.
Binary Output - 24 VAC Triac (External Power Source)
Connects OUTn to OCOMn when activated.
External Power Source Requirements:
30 VAC maximum output voltage
0.5 A maximum output current
1.3 A at 25% duty cycle
40 mA minimum load current

Binary Output Common (for OUTn terminal)
Note: Each Binary Output Common terminal (OCOMn) is
isolated from all other commons, including other Binary
Output Common terminals.
OCOMn
See Guideline C in Table 4.
Binary Output - 24 VAC Triac (Internal Power Source)
Sources internal 24 VAC power (24~ HOT).
