- Four channels can provide either ±10 V voltage or 0...20 mA current outputs
- Voltage resolution is 320 µV per bit and current resolution is 325 nA per bit
- Settling time is less than 2 ms to 95% of final value with resistive loads
1756-OF4 is an Allen-Bradley ControlLogix four-channel voltage/current analog output module for chassis-based control systems.
Each channel supports ±10 V or 0...20 mA operation with configurable scaling, program and fault states, clamping, ramping, calibration, and open-circuit detection in current mode.
Before installation or replacement, verify hardware Series, firmware, chassis Series, signal mode, scaling, load impedance, terminal block, shielding, calibration, and the saved Logix configuration.
Availability, condition, price, and shipping time for 1756-OF4 are confirmed during quotation.
