The Allen-Bradley 1756-L62 is discontinued ControlLogix controller that features an integrated user memory of 4MB. This controller entered discontinued phase on June 01, 2017 with a functional replacement of 1756-L72 therefore, this module is a spare part item. Furthermore, The entire 1756-L62x is functionally replaced by 1756-L72x.

ControlLogix controllers are capable of implementing complex control of medium to large processes. It may be used in Factory or Process automation applications. It can handle up to a maximum count of I/O amounting to 128,000.

This controller requires a user program to be downloaded to it. Both Series A and B are compatible for use with any version of RSLinx.

Additionally, this controller also supports inter-controller communication where data inside the controller is sent to another controller in the network via a specific instruction, depending on the communication module used. This controller can host up to 250 simultaneous connections. Specific network connections per module include 100 connections for ControlNet using 1756-CN2/A; 40 connections for ControlNet using 1756-CNB/D or 1756-CNB/E; 128 connections for ControlNet using 1756-CN2/B and 256 EtherNet/IP; 128 TCP using 1756-EN2x and 128 EtherNet/IP and 64 TCP with 1756-ENBT.

The Allen-Bradley 1756-L62 is a ControlLogix controller. It has an integrated user memory of 4 MB and an I/O memory of 478 KB. An optional nonvolatile memory storage may be installed for this controller for expanding the internal memory with the use of CompactFlash 1784-CF128. The controller is only compatible with certain 1756 chassis, namely 1756-A4, 1756-A7, 1756-A10, 1756-A13, and 1756-A17. The 1756-L62 has two types, Series A and Series B.

The 1756-L62 supports 32 tasks with 100 programs per task including even tasks for all event triggers. It also has an RS232 serial port that supports several communication protocols. Protocols being supported by the RS232 port include DH-485, DF1 radio modem, DF1 full/half-duplex, Modbus via logic, and ASCII. This controller also supports other communication protocols such as Remote I/O, ControlNet, SynchLink, EtherNet/IP, Third-party process and device networks, Data Highway Plus, and DeviceNet. It can support a maximum of 250 controller connections and also offers full support to controller redundancy.

This controller has a maximum total I/O of 128,000, a maximum analog I/O of 4000, and a maximum digital I/O of 128,000. It has a current draw of 14 mA at 24V DC and 1200 mA at 5.1V DC. It has an isolation voltage of 30V (continuous) has been type tested at 720V DC for 60s. The 1756-L62 has a thermal dissipation of 11.9 BTU/hr and a power dissipation of 3.5 W. Its storage temperature ranges from -40 to 85 Degrees Celsius and its operating temperature is from 0 to 60 Degrees Celsius. It also has a noncondensing relative humidity of 5% to 95% and a maximum surrounding air temperature of 60 Degrees Celsius. It has a vibration of 2 g at 10 to 500 Hz, an operating shock of 30 g, and a non-operating shock of 50 g.
