1747-L30C

The 1747-L30C is an Allen-Bradley fixed style controller. This controller is ideal for use in small scale applications. It has integrated IOs such as (18) 24 Volts DC Sinking, High-Speed inputs and (12) AC/DC Relay.

Fixed style hardware are cost effective - products with limited expansion capability. The modules that can be installed with this fixed style hardware are standard SLC 500 modules such as input and output modules. Specialty and Intelligent modules when used with this fixed style controller are installed in the 2nd slot or slot no. 1. The main difference of 1747-L30C with 1747-L30A is the embedded capability of receiving High-Speed inputs. It functions similarly with the 1747-L30A.

This SLC controller may be used with a Data Access Table Module (DTAM), configured and programmed with the use of a Handheld Terminal or 1747-PT1, Isolated link coupler such as 1747-AIC and advanced coupler like 1747-NET-AIC.

This product is announced discontinued on July 31, 2009. Appropriate replacement for this controller includes MicroLogix or CompactLogix controllers.

Though this SCL fixed style controller is designed for small application, it is capable of being communicated with Supervisory Control and Data Acquisition (SCADA) and Human Machine Interface (HMI) system and devices. It may also be used for exchanging data with PLC 5 controllers provided an appropriate communication module via the 1747-DCM. Specifically, PLC 5/15 or PLC 5/25 may be communicated with SLC 5/01, 5/02 and 5/03. If direct communication with SLC controllers is used, the host controller may be installed with a 1747-SN while the client controller is installed with a 1747-DCM.

The 1747-L30C is an Allen-Bradley PLC SLC 500 Series Fixed Hardware Controller. This fixed controller has a processor with a power supply and a fixed number of I/O within a single package. With capacitor-backed RAM as its memory type, the 1747-L30C offers optional battery back-up and EEPROM and UVPROM memory backup options. It has a 1K instruction capacity of program memory and a nominal input current of 12mA. The 1747-L30C possesses an I/O configuration input of (18) 24V DC sink and an I/O configuration output of (12) AC/DC Relay. The 1747-L30C operates under 21.6-26.4V DC or 24V DC +/-10% power supply input. This controller communicates via DH-485 protocol.

In addition, the 1747-L30C has a maximum power supply (Inrush Rating) of 30 Amperes and a maximum power requirement of 50 VA. In addition, the 1747-L30C uses a wire size of #14 AWG maximum and caters I/O electrical-optical isolation of 1500V AC at 1 minute. Operating in an ambient temperature rating of 0-60 deg. Celsius (32-140 deg. Fahrenheit), this PLC module must be stored at the temperature of -40-85 deg. Celsius. The 1747-L30C works with a High-Speed Counter and 24V-200mA user power. With an on-state voltage of 10-30V DC and a maximum off-state voltage of 4V DC for input 0 (5V DC for all others), the 1747-L30C has a maximum turn-on time and turn-off time of 8 milliseconds. Moreover, the 1747-L30C has a typical scan time of an 8 milliseconds/1K and a program scan hold-up time after power interruption of 20-700 milliseconds. The power output current of the 1747-L30C controller is 200mA and its power output voltage is 20.4 - 27.6V DC or 24V DC +/- 15 %.
