PRODUCT INFORMATION
Product Overview
The Allen-Bradley 1771-NOV is an analog output module designed for PLC-5 control systems. The unit provides eight voltage output channels. Each output channel operates across a range of positive and negative ten volts direct current. It mounts directly into an Allen-Bradley 1771 rack. The module requires 2.1 amperes of backplane current.
This N-Series hardware supports natural binary and binary-coded decimal data formats. Field connections route through the 1771-WH wiring arm. Installations can also use 1771-RTP3 fused or 1771-RTP4 unfused remote termination panels. The typical direct-current signal turn-off delay is 50 milliseconds. Alternating-current signal turn-off delay averages 45 milliseconds.
