Function, ratings, requirements
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.
Binary Output - 24 VAC Triac (External Power Source only)
Connects CO-n to CO-Cn when activated.
External Power Source Requirements:
24 VAC maximum output voltage
0.5 A maximum output current
40 mA minimum load current
Analog Output Signal Common All Configurable Outputs
(COs) defined as Analog Outputs (AOs) share a common,
which is isolated from all other commons except the Binary
Input common.
Binary Output Signal Common All Configurable Outputs
(COs) defined as Binary Outputs are isolated from all other
commons, including other CO commons.
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.
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 with impedances greater than
300 may not operate as intended for Current Mode
applications.
Analog Output Signal Common for all Analog Output
terminals.
Note: All Analog Output Common terminals (AO-
Cn) share a common, which is isolated from all other
commons.
Binary Output - 24 VAC Triac (External Power Source)
Connects BO-n to BO-Cn when activated.
External Power Source Requirements:
24 VAC maximum output voltage
0.5 A maximum output current
40 mA minimum load current
Binary Output Common for all Binary Output terminals.
Note: Each Binary Output Common terminal (BO-Cn) is
isolated from all other commons, including other Binary
Output Common terminals.
