Figure 15. Dry contact/binary outputs
Note: Output wiring specifications must comply with the receiving device wiring requirements.
Important: Inrush Current and Controlling Coil-based Loads: Inrush current (the initial surge of a current
into a load before it attains normal operating condition) can be more that three times
greater than the operating current.
Use pilot relays for dry contact outputs for load currents greater than 0.5 amperes and use
powered outputs for load currents less than 0.5 amperes.
To wire relay binary outputs:
1. Connect the shield to a common terminal at the terminal board and tape it back at the output device.
2. Connect the signal wire to an available output terminal.
3. Use the Tracer TU service tool to configure the input for binary operation.
Note: Polarity is normally open (NO) or ON. However, you can use the Polarity control (toggle) on
the Binary Output Point Configuration dialog box to reverse polarity to normally closed (NC)
or OFF.
TRIAC Wiring
The Symbio 500 has six (6) TRIAC binary outputs. The following illustrations show wiring to TRIAC
binary outputs (low/high).
