This product is a Controller that belongs to the PLC5 product family. It is mounted to a PLC5 chassis such as 1771-A1B, 1771-A2B, 1771-A3B, 1771-A3B1, and 1771-A4B.\u003c\/p\u003e\n\u003cp\u003eThis controller is ideally used for medium to large automation application as it is built with a 48KWords user memory capable of handling any combination of I\/O devices with total count of 2048 points or 2048 input and 2048 output devices for complementary configuration. With the increased I\/O capacity, this controller can also handle up to 29 PLC 5 racks, composed of 1 local rack and 28 Remote I\/O rack. The local rack refers to the rack where the controller is installed.\u003c\/p\u003e\n\u003cp\u003eThis controller is also built with Four (4) DH+ or Remote I\/O (Adapter or Scanner) combination port, One (1) serial port, configurable for RS-232 and 423 and RS-422A communication standards. Each of the combination port may be used with separate networks, allowing the controller to implement Four (4) independent DH+ \/ RIO networks. The serial communication channel allows point-to-point interface which is also ideally used for short distance communication.\u003c\/p\u003e\n\u003cp\u003eAdditional EEPROM or backup memory devices may be installed to serves as the controller’s non-volatile memory. Available memory cards are 1785-ME16 for 16K words, 1785-ME32 for s 32K words, 1785-ME64 for 64K words and 1785-ME100 for 100K words.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"Allen Bradley","offers":[{"title":"Default Title","offer_id":43671252926552,"sku":null,"price":823.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0580\/2799\/9320\/files\/1785-L40B-.0.jpg?v=1768818946","url":"https:\/\/gexufein.com\/products\/allen-bradley-1785-l20b-programmable-logic-controller","provider":"Gexufein Automation","version":"1.0","type":"link"}
