Your transmitter has up to five channels to support I/O and communications. The channels are named
Channel A, Channel B, Channel C, Channel D, and Channel E. You can configure Channels B, C, and D to
operate in several different ways. You can also configure Channels A, B, C, and D to draw power from the
transmitter (internal, active) or from an external power supply (external, passive).
Restriction
•
Channel A is always used as an mA output. You can configure the power for Channel A.
•
Channel E is always used for RS-485 communications. You cannot configure the power for Channel E.
Depending on your purchase order, some channels may not be activated on your device. To see which
channels are activated:

Important
The channel configuration must match the I/O wiring.
Prerequisites
Plan your channel assignments before configuring channels. Not all combinations are supported. For
example:
•
You cannot have both a Frequency Input and an mA Input.
•
You cannot have three Discrete Outputs and a Frequency Output.
.
If you plan to use dual-pulse mode, configure Channel C as Frequency Output 1, and either Channel B or
Channel D, or both, as Frequency Output 2.
Important
To avoid causing process errors:
•
Configure the channels before configuring the outputs or inputs.
