The Allen-Bradley 1756-L55M22 is a ControlLogix controller module. A battery-backed 750 KB user memory unit is available on the 1756-L55M22, and 63 days is the minimum backup time provided by the 1756-BA1 memory unit, while the 1756-BATA and 1756-BATM battery modules provide a minimum of 299 days of backup (the battery backup specifications are valid for a maximum ambient temperature of 77 degrees Fahrenheit). An integrated 750 KB non-volatile memory is also provided which can be enhanced by installing optional 64 MB or 128 MB CompactFlash memory modules. Up to 208 KB of I/O memory for the storage of I/O tags, consumed tags, and produced tags is also available.
One serial port is provided on the 1756-L55M22 which supports multiple protocols including the ASCII, DH-485, and DF1. The programming languages which can be used include the SFC, relay ladder, function block, and structured text. The recommended serial programming cables include the 1756-CP3 and 1747-CP3. Integration with other networks is made possible through optional communication modules which include Ethernet, Remote I/O, DH+, and DeviceNet networks. The 1756-L55M22 is installed inside a slot in a 1756 I/O chassis and its current draw is 1.23 Amps at 5 Volts DC or 14 milliamps at 24 Volts DC. The thermal dissipation of the module can go up to 19.1 BTU/hour and the power dissipation can go up to 5.6 Watts. The 1756-L55M22 requires a 32 to 140 degrees Fahrenheit ambient temperature range and 5 to 95% relative humidity for optimal performance. It can withstand 2G of vibration at 10 to 500 Hertz and 30G of shock.
