Binary Output - 24 VAC Triac (External Power Source
only)
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
Same as (Configurable) OUTn.
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

Cable and Wire Length
Guidelines
Table 4 defines cable length guidelines for the various
wire sizes that may be used for wiring low-voltage (<30V)
input and outputs.

100 mV maximum voltage drop
Depending on cable and the connected input
or output device, you may have to define an
offset in the setup software for the input or
output point.
