The Allen-Bradley 1756-72 ERoms is an armored GuardLogix controller. It comes with 2 channels, a 4MB standard memory, 0.98MBIO memory, and a 2MB secure memory, allowing standard and secure communication options on the EtherNeVIP network. The controller has a maximum analog VO of 4000 and a maximum digital VO and total IO of 128,000, respectively. The 1756-L72EROMS also comes with an additional 1GB SD card memory that is installed to the controller, but you can upgrade it to 2 GB.
This controller can support up to 256 EtherNETips and 128 TCP network connections per network module. Note that the 1756-L.72EROMS controller does not have controller redundancy. Available programming languages include structured text, Sequential Function diagrams (SFC), relay logic (RLL), RLL-only security tasks and additional security application instructions, and function block diagrams. The controller has an Ethernet RJ455 class port and a full speed USB port. The 1756-L72EROMS measures 9.4x11.5x6.5 inches, weighs 7.15 kg or 15.725 pounds and has a UL Type 4/4x housing type.
The nominal input voltage of the controller is 24VDC, and its input range is 18-32VDC. The continuous isolation voltage is 30V, which belongs to basic insulation type. This isolation has been type-tested for 6D seconds at 707VDC, from the power supply to the chassis, from the non-redundant Ethernet channel to the non-redundant Ethernet channel, and from the Ethernet channel to the power supply, but there is no isolation between the redundant Ethernet channels. The controller has a non-replaceable fuse that is soldered in place to prevent fire caused by short circuit conditions.
The operating temperature of the 1756-L72EROMS is 0-6O ° C and the storage temperature is -40-85 ° C. Its maximum ambient temperature is 60EsC, the relative temperature is 5-95%, and there is no cold solution. The working vibration of the controller is 50g at 2-10H. The working shock is 30g and the non-working shock is 30g.
