Analog Output Functions
The 1769-OF2 provides two analog output channels for transmitting control signals to compatible field devices. Voltage output ranges support different signal requirements, while current ranges include 0-20 mA and 4-20 mA. The selected signal type and range must match the receiving device and the intended control configuration.
The Sigma-Delta conversion method translates digital output values into analog signals. The specified maximum conversion rate is 2.5 ms for all channels. This parameter describes conversion timing and should not be interpreted as a guarantee of the complete control-loop response time.
Protection and Module Identification
The module includes open-circuit, short-circuit, and output overvoltage protection. These features address specific electrical fault conditions, but they do not eliminate the need to verify wiring, load requirements, and permitted operating conditions.
The status LED supports visual identification of module status. The locking bus lever and nameplate label also help with module identification and physical assembly.
Frequently Asked Questions
Q: What output signals does the 1769-OF2 support?
