1771-OFE1 Description

The 1771-OFE1 is an analog output module from the PLC series.  This module delivers voltage signals which can be 

used to drive modulating devices such as control valves, adjustable frequency AC drives, Dampers, louvers, and positioners.  

It may also be used as a signal source of data loggers, splitters, panel meters, totalizers, and single loop controllers.  

The 1771-OFE1 output voltage ranges include +1 to +5 VDC;  -10 to +10 VDC and 0 to +10 VDC.  It has a digital resolution 

of 12 bits with a Digital to Analog (DAC)converter maximum settling time of 0.8 ms for a resistive load.  The module’s 

internal scan rate is 8.0 ms for every channel utilizing Binary Coded Decimal (BCD) data and scaling and 1.6 ms for 

all channels using binary data and no scaling.  The 1771-OFE1 analog output module accuracy is +0.1% of full scale;  

+1/2 Least Significant Digit (LSD) when operating in BCD mode and +1/2 Least Significant Bit (LSB) when configured in 

Binary mode.  This module is a single slot module that directly installs to a Bulletin 1771 I/O chassis.  It has a 

power dissipation of 7.9 Watts and backplane power consumption of 1.50 Amperes while the thermal dissipation is 

26.9 BTU / hr.  The 1771-OFE1 operating temperature is 32 to 140 Degrees Celsius;  Operating shock of 30 g and 

operating vibration of 2g at 10-500 Hz.  For module storage, it must be kept in an environment with temperatures 

-40 to 185 Degrees Celsius.  Each output of this module has built-in overload protection against short circuit load conditions.
