The Allen Bradley 1769-OF8V Programmable Controller module has eight (8) Single ended Voltage outputs are available in the module.
It only has a single group of outputs with resolution of 16 bits plus sign (bipolar) ±10V DC: 15.89 bits, 330 ?V/bit 0…10V DC: 14.89 bits, 330 ?V/bit 0…5V DC: 13.89 bits, 330 ?V/bit 1…5V DC: 13.57 bits, 330 ?V/bit.
Single ended wiring are more susceptible to noise and electrical disturbance than differential wiring. Ensure that proper module and signal grounding is implemented to be able to obtain accurate readings.
The 1769-OF8V has modules series A and B. Series A does not allow the use of an external power supply while series B module allows external 24VDC power.
The module operates by converting the binary data residing at the CPU’s memory registers. The analog output captures the data and converts to analog format with the internal Digital to Aanalog Converter (DAC). Data formats available are Raw / Proportional data, Engineering unit, Scaled for PID and Percent full range.
The Allen Bradley 1769-OF8V compact I/O is a compact output module with eight single-ended outputs and an output voltage range between 0 to 10V. It is an output module with about 10V DC and 15.89 bits at a 330 ?V/bit resolution. The 1769-OF8V draws a current of 145Ma at 5.1V and dissipates heat at 2.1W. It has a maximum conversion rate of 5.0ms and a 63% step response at 2.1ms. The 1769-OF8V module has a resistance output load of more than > 1 k? at 10V dc.
The 1769-OF8V compact I/O compact module can maintain a capacitive load of up to 1?F and requires no field calibration. It is a device with a +/- .5% full scale at 77 degree Fahrenheit accuracy and a +/- 0.8% margin module error. The 1769-OF8V has an offset error margin of ±0.05% at an impedance of less than 1?. It offers short-circuit protection for up to 30mA as well as protection from excess voltage.
The 1769-OF8V module has a powerup time of less than 5ms, and when it is operational, it has a rated voltage of 30V DC. Its dimensions are 4.65 x 1.38 x 3.43 in. and it weighs about 0.58 lb. It is a special compact module with a power supply rating across 8 modules with a copper wire.
