By maintaining 100K EEPROM non-volatile memory storage, the cartridge preserves active ladder logic and controller configurations across unexpected power interruptions. Operating at a backplane current draw of 0.17 A at 5 VDC, the module executes memory transfer routines during boot initialization without degrading backplane bus communication velocity across adjacent PLC-5 rack slots.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: Can the 1785-CHBM backup cartridge be inserted or removed while backplane power is applied?\u003c\/p\u003e\n\u003cp\u003eA: No. Inserting or removing the memory module while the CPU is powered can lead to EEPROM data corruption or system faults. Shut down chassis power prior to module extraction or insertion.\u003c\/p\u003e\n\u003cp\u003eQ: How does the 1785-CHBM restore system memory upon controller initialization?\u003c\/p\u003e\n\u003cp\u003eA: When configured in CPU parameters, the 1785-CHBM transfers its stored 100K EEPROM program image into processor RAM during power-up or upon detection of RAM memory corruption.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003col\u003e\n\u003cli\u003eDisconnect main AC power from the 1785 PLC-5 chassis and verify processor power LEDs are extinguished.\u003c\/li\u003e\n\u003cli\u003eWear a grounded anti-static wrist strap to prevent electrostatic discharge (ESD) damage to memory chips.\u003c\/li\u003e\n\u003cli\u003eLocate the designated memory cartridge slot on the front face of the ControlNet PLC-5 processor module.\u003c\/li\u003e\n\u003cli\u003eAlign the 1785-CHBM module edge keyways with the socket guides and press firmly until fully seated.\u003c\/li\u003e\n\u003cli\u003eRe-apply chassis power and confirm non-volatile memory detection using RSLogix 5 \/ 6200 programming software.\u003c\/li\u003e\n\u003c\/ol\u003e","brand":"Allen-Bradley","offers":[{"title":"Default Title","offer_id":48747669291198,"sku":"1785-CHBM","price":89.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0725\/1145\/5422\/files\/1785-CHBM_7ff85542-187b-45e4-acfc-f32d6eb3ad2a.png?v=1786957737","url":"https:\/\/www.autooiltech.com\/products\/allen-bradley-1785-chbm-controlnet-plc-5-backup-cartridge","provider":"AutoOilTech Limited","version":"1.0","type":"link"}
