Allen-Bradley1756-OF4 SER A ControlLogix 4 Pt A/O I or V Module

Description For1756-OF4

The 1756-OF4 is a ControlLogix Four (4) channel analog output module. This module has an output Voltage and Current signals with ranges of -/+ 10VDC and 4-20 mA signals respectively. This module is used to drive modulating actuators and devices. This module is directly installed to any 1756 ControlLogix chassis.

The 1756-OF4 module has voltage and current ratings of 5.1V DC for the backplane, a maximum of 150 milliamps for 24V DC. It has a current draw of 150 milliamps at 5.1V and 120 milliamps at 24V and a total backplane power of 5.8 W. Its power consumption is 3.7 W of backplane power and its overvoltage protection is 24V DC. The module’s open circuit detection is only for current output, but the output should be set to greater than 0.1 milliamps. It also has a short-circuit protection that is limited to 21 milliamps or less.

With an output range of 0 to 20 milliamps, it has a low signal and user count of 0 milliamps and -32768 counts and a high signal and user count of 21.2916 milliamps and 32767 counts respectively. At an output range of +/- 10V, the module’s low signal and user count are -10.4336V and -32768 counts and the high signal and user count are 10.4336V and 32676 counts respectively. It has been routine-tested for 2 seconds at 1350V AC and has a continuous isolation voltage of 250V.

This module as a voltage drive capability of greater than 2000 ohms and a current drive capability of 0 to 750 ohms. It has a module scan time of 12 ms floating-point and a scan time of 8 ms integer with a module error of 0.15% of the range for voltage and 0.3% of the range for current. Its settling time is less than 2 ms to 95% of final value with resistive loads. It also has a maximum power dissipation of 3.25 W (4 channel current) and a thermal dissipation of 10.91 BTU/hr.

The Allen-Bradley 1756-OF4 is an analog output module that is capable of providing analog voltage and current signals. These output signals may be used to actuate modulating devices and actuators or used to retransmit signals for use by recorders, indicators, data loggers and external controllers.
