The 1201-HCS2 module is a programmer controller interface module with a digital potentiometer. It has been designed and manufactured by Allen-Bradley. It is used with Allen-Bradley 1336 adjustable frequency AC drives. The operators can use this module to send input data, adjust drive settings, and troubleshoot the drive when needed. The front side of the interface has a backlit LED screen. It displays information in a monochrome color. Beneath the display screen, there are different keys that are made for executing different functions. The 1201-HCS2 module comes with up and down arrow keys for navigating between menu options, an escape key to cancel the current application execution, and a select key to select different menu items. It also comes with local power and control keys. The drive can be turned on and off by using the power keys housed on the human-machine interface module. The mounting of the module can be done using the snap-in cradle. This module is easy to mount using this cradle

The 1201-HCS2 human-machine interface module is a Series A operator interface terminal. It comes in a compact package and it weighs only 1.6 pounds. The interface module is equipped with a microprocessor that is used to process all the operations. The module can only be operated in a temperature range between 0 and 50 degrees Celsius. The operating temperature of the module is maintained using the convection cooling method. Proper clearances should be left around the module during the installation and mounting processes. The 1201-HCS2 module is certified with the CE-EMC, CE-LVD, KC, and UL standards. It is fully compatible with frame sizes A to D.
