GE Fanuc IC697PWR711K Series 90-30 Platform Power Module

Description

The IC697PWR711K is a power supply module from the Ge Fanuc 90-30 Series Programmable Logic Controller (PLC) family. This module has a selectable input voltage compatibility such as 120 VAC and 240 VAC, dictated by an external jumper setting. For both the nominal vali input voltages, the applicable voltage range are 90 to132 VAC or 180 to 264 VAC, with frequency of 47 to 63 Hz.

The IC697PWR711K has output voltage supply of +5VDC, 12VDC and -12VDC and logic level sequencing signals towards the backplane. This power supply is mounted on the leftmost location of the 90-30 rack, attached via the 48-pin backplane connector. This power supply is capable of supplying power to a second rack provided that the total load of the additional rack will not exceed the total 100 Watt capacity of the IC697PWR711K. Specifically, the 2nd rack must be less than 5.2 amperes. Additionally, powering the 2nd rack requires use of 3-feet connecting cable. The 2nd rack must be within the reach of this cable as it is not designed to operated more than 3 ft.

The has a slide in rack mount construction. The +5VDC delivers maximum output of 18 amperes, +12VDC a maximum output of 2 Amperes and maximum 1 Ampere from the -12VDC output. This power supply has an internal electronic short-circuit and overcurrent protection. For branch circuit fusing, an external switch that is appropriately sized must be installed. This power supply has an ON / OFF switch to put the power supply to active operation.

This module features a slide-in rack construction and 2-rack operation from a single power supply.

The GE Fanuc Automation IC697PWR711K power supply module includes electronic short circuit protection and a power factor correction when it is operating with AC voltage. If the GE Fanuc Automation IC697PWR711K power supply module is meant to have continuous operations in environments with high temperatures and low line voltages, its specifications must be derated to guarantee safe operations. Normal operations are only possible with temperatures below 60 degrees Celsius. The GE Fanuc Automation IC697PWR711K power supply module is installed in the left slot of a GE IC697 rack or any VME integrator rack and it is a plug-in module type. This module comes with an input half-cycle peak inrush current of 3 Amps.

The concept of fieldbus
According to the definition of the International Electrotechnical Commission (IEC 61158) standard, fieldbus refers to the industrial data bus, which includes digital, multipoint, and serial communication, applied between field devices in the manufacturing process area and automatic control devices in the control room. It is an open, digital, and multi-point underlying communication network. The industrial control system centered on fieldbus technology, known as the Fieldbus Control System (FCS), is a new network integrated fully distributed control system developed since the late 1980s.
Among them, the fieldbus system is generally referred to as the fifth generation control system. The first generation control system was the pneumatic signal control system PCS before the 1950s, the second generation was the electric analog signal control system with 4-20mA, the third generation was the digital computer centralized control system, and the fourth generation was the distributed control system DCS since the mid-1970s.

Fieldbus technology
Fieldbus technology incorporates specialized microprocessors into traditional measurement and control instruments, enabling them to have varying degrees of digital computing and communication capabilities, becoming network nodes capable of independently undertaking certain control and communication tasks. They transmit information through various channels such as ordinary twisted pair, optical fiber, coaxial cable, etc., thus forming a network system connected by multiple measurement and control instruments, computers, etc. as nodes. This network system achieves data transmission and information sharing between multiple computerized automatic control devices located on the production site, as well as between on-site instruments and remote computers used for management and monitoring, in accordance with standardized and publicly available communication protocols, further forming various automatic control systems that meet practical needs. As shown in Figure 1, it is a simple fieldbus system.
