Relay and FET Output Loads – The maximum controlled load for the 1766-L32BXB and 1766-L32BXBA is 1080 VA.  For the 1766-L32BWA, 1766-L32AWA , 1766-L32BWAA and 1766-L32AWAA, the maximum controlled load is 1440 VA.

MicroLogix 1400 controllers have a serial number in addition to their catalog number.  This serial number indicates which generation of controller is existence used.  Series A indicates the initial introduction of the 1400 series line.  There are a few differences between series when using and programming a MicroLogix 1400 controller.

• Communication Cable – The 1400 requires the employ of specific communication cables which may vary based on serial.  For example, cables 1763-NC01 and 1747-CP3 can be used on series A controllers and later.  Still, in that location is a long list of cables that tin can just be used on series C or later.  These include:
  • 1761-CBL-AM00
  • 1761-CBL-AP00
  • 1761-CBL-PM02
  • 1761-CBL-HM02
• Software Release – The MicroLogix 1400 uses RSLogix 500 equally its software platform.  Series A controllers can use RSLogix 500 version 8.i or higher.  Series B and C must use RSLogix 500 version 8.3 or afterward.
• Firmware – The determination of which firmware to employ volition largely depend on which functionality the user wants to enable.  Each successive firmware upgrade enables new functionality and then the user will demand to be enlightened of what is required of the control organisation.  For instance, Series A controllers can only flash firmware upgrades through FRN7.   For B and C series controllers, Allen-Bradley recommends using FRN-21.006, which introduced countersign enhancements to the programming along with other features.  Other firmware upgrades available by series is:
  • FRN 21.005 – Series B and Series C only
  • FRN 21.000 Series B and Serial C only
