SLC 500 8-Point Analog Output Module Hardware Features The module contains a removable terminal block, providing connection for 8 analog output channels, which are specifically designed to interface with analog current and voltage devices. The 1746-NO8I provides eight channels of current outputs, while the 1746-NO8V provides eight channels of voltage outputs. -
Page 6: Determining Power Requirements
SLC 500 8-Point Analog Output Module Determining Power Requirements The module receives its power through the SLC 500 chassis backplane from the +5V dc/+24V dc chassis power supply. The +5V dc backplane supply powers the SLC circuitry, and the +24V dc backplane supply powers the module analog circuitry. - Page 7 SLC 500 8-Point Analog Output Module • With the jumper in the 1-2 shorted position, the module draws all of its power from the backplane of the SLC system. • With the jumper in the 2-3 shorted position, the module draws its 24V dc power from the external power supply;...

Page 8: Installation
SLC 500 8-Point Analog Output Module Installation Install the SLC 500 system in a properly rated (i.e., NEMA) enclosure. Make sure that the SLC 500 system is properly grounded. Choosing a Slot in the Chassis Two factors determine where the analog module should be located in the chassis: ambient temperature and electrical noise. - Page 9 SLC 500 8-Point Analog Output Module Remove Power Remove power before removing or installing this module. ATTENTION When you remove or install a module with power applied, an electrical arc may occur. An electrical arc can cause personal injury or property damage by: •...
- Page 10 SLC 500 8-Point Analog Output Module Module Installation and Removal The module fits into any slot, except the processor slot (0), in either an SLC 500 modular system or an SLC 500 fixed system expansion chassis (1746-A2). 1. Align the circuit board of the analog module with the card guide of the chassis as shown below.

SLC 500 8-Point Analog Output Module Wiring Preliminary Considerations Use the following guidelines in planning the system wiring for the analog modules: Before wiring any analog module, disconnect power from the ATTENTION SLC 500 system and from any other source to the analog module. - Page 12 SLC 500 8-Point Analog Output Module Wiring Procedure To wire your module, follow these steps: 1. Determine the length of cable you need to connect a channel to its field device. Remember to include additional cable to route the shield wire and foil shield to their ground points.
- Page 13 SLC 500 8-Point Analog Output Module Terminal Block The 1746-NO8 module contains an 18-position, removable terminal block. The terminal pin-out is shown below. Disconnect power to the SLC before attempting to install, ATTENTION remove, or wire the removable terminal block. To avoid cracking the removable terminal block, alternate the removal of the slotted terminal block release screws.
