1785-L46C15

The 1785-L46C15 PLC-5/46C is a Controller with a ControlNet Network, a 48,000 Word SRAM programmable controller, and a 1771 I/O Chassis. It is made for industrial processes and for controlling the outputs and inputs of field devices. It has a 48K processor with a limit of 32K words per data-table file, and a maximum I/O capacity of 2048. It also has a 15 I/O Rack capacity and a 60 I/O chassis capacity, and it has 2 front panel 3-pin ports configured for DH+ or remote I/O communications (adapter or scanner), and 1 coprocessor port. The 1785-L46C15 has a base-configured ControlNet (Redundant) port with 5M bit/s port speed, and with 99 Nodes per link (with repeaters). Its remote I/O and DH+ port have a transmission speed ranging from 57.6K bit/s to 230.4K bit/s and with an I/O port scan time that ranges from 10ms per rack at 57.6K bit/s to 3ms per rack at 230K bit/s.

The 1785-L46C15 draws a 3.3A backplane current at 5V DC, and it has 59 BTU/hour of maximum thermal dissipation when operational. It supports the Allen-Bradley 1785-CHBM ControlNet Hot Backup Cartridge that is used for system backup, and it is compatible with the 1771, 1794, 1746, and the 1791 8-point, 16-point, 32-point, and I/O modules. The 1785-L46C15 also supports the ½ slot, single slot, and double slot hardware addressing system and it is keyed to the chassis via pins 40 and 42 and pins 54 and 56. It has a thermal dissipation of 59 BTU/hour, and an operating temperature of 0-60 oC (32-140 oF), at 5-95% non-condensing relative humidity, and a storage temperature range of –40-85 oC (–40-185 oF). The controller can tolerate a 30G operational shock, with 1G vibration at 10-500Hz, and it is designed with an open-style enclosure. The 1785-L46C15 weighs around 1.42kg (3lbs), and it is UL, CE, CSA, and C-TICK-certified.
