FACTORY SEALED Allen Bradley 1747-L531 /F 5/03 SLC 500 Processor Controller

About 1747-L531:

The AB 1747-L531 is an SLC 5/03 processor type module that belongs to the SLC 500 Modular Hardware Style series. It is built to perform a large variety of functions, including small, simple stand-alone systems to large, complex distributed ones. Designed to perform throughput, it can support 60 various I/O modules including analog, digital, and intelligent I/O’s and can, in addition, control up to 4,096 output and input points. It ships with the SLC 500 modular processor, a compatible chassis, power supplies, and installation instructions for all the included parts. This module is C-Tick marked, CE compliant, and UL listed to Canadian and US Safety Standards,

The 1747-L531 Modular Processor comes with a memory size of 8 K, 16 K, or 32 K for its programs. This user-configurable memory can be applied either to program storage or to data storage. The drive features a battery-backed RAM that lasts approximately 2 years. The BATT LED indicator alerts user when the voltage of the replaceable battery has fallen below the threshold level. A minimum of thirty (30) minutes of power is available when the battery is disconnected, due to an integrated capacitor. If a new battery is installed to replace the old one within half an hour (30 minutes), any data stored in the RAM can be retained. The 1747-L531 Processor receives and initiates communication protocols including DH-485 peer-to-peer, ControlNet, Ethernet, Data Highway Plus (DH+), DeviceNet, Modbus RTU Master, as well as full-duplex or half-duplex master or slave DF1, ASCII and DH-485 via the RS232 port. Its front panel has a 3-position key switch that allows three operation modes: PROGram, RUN, and REMote. This key switch cannot be used in place of an emergency-stop switch or a hardwired master control relay.
