PRODUCT INFORMATION
Product Overview
The Allen-Bradley 1746-NO4V is an analog output module for the SLC 500 series. It mounts directly into any available slot in a 1746 chassis. The module provides four distinct analog voltage output channels. Supported voltage ranges include -10 to 10 VDC and 0 to 10 VDC. Channels also support 0 to 5 VDC and 1 to 5 VDC ranges.
Backplane current draw is 55 mA at 5V DC and 145 mA at 24V DC. An external 24V DC power supply option is also supported. All four outputs update in parallel within 512 microseconds. Isolation between backplane and field wiring is rated at 500V DC. Connections use a removable terminal block accepting up to #14 AWG wire.
