product details
The 1785-L20E has a built-in volatile memory that amounts to 16KWords, which is maintained by a Lithium battery with catalog number 1785-XYC. This battery provides the necessary energy to maintain the contents of the controller's SRAM to allow the controller to continuously function. For backup and increased system availability, non-volatile memory back up devices may be installed such as 1785-ME16 with 16Kwords, 1785-ME32 with 32Kwords, 1785-ME64 with 64 Kwords and 1785-ME100 with 100Kwords.
The 1785-L20E's embedded communication interfaces include One (1) DH+ dedicated interface, One (1) DH+/Remote I/O (Adapter or Scanner) combination interface, One (1) serial port that supports RS-232, 423 and RS-422A standards and One (1) Ethernet channel that supports 10/100 Mbps transmission speed.
The 1785-L20E supports installation of Thirteen (13) chassis, overall. This includes the local rack where the controller is installed and additional Twelve (12) racks that me be used as distributed I/O racks.
The 1785-L20E supports a variety of data types such as Immediate or program constant, Integer, Float, Block, Message, PID, String and SFC status.
The 1785-L20E PLC -5/20E Ethernet/IP Programmable Controller by Allen-Bradley is a programmable controller with 16K word SRAM processor. This controller is installed in a 1771 I/O chassis' controller slot. It is primarily used for processing user logic and for controlling the inputs and outputs of field devices connected to it. It has 512 maximum I/O link capacity with 512 mixed, or 512 in + 512 out complementary. The controller's supported I/O Rack capacity is Four (4) and a Remote I/O chassis capacity of 12. The controller is installed on either the 1771-A1B, -A2B, A3B, -A3B1, or the -A4B I/O chassis, and draws a chassis backplane current of 3.6A.
