SIEMENS

Application

Control Stations for Power Plants – SIBAK range.

Description

These Control Stations are used in Thermal/Hydroelectric Power Plants to monitor and control the transmission and distribution of electricity. These items were exclusively made for Siemens as part of a drive to develop products locally. A variety of control stations were developed like Auto/Manual Stations, Drive Stations, Set Point Setters, Bias Setters (With & Without Indicators), Dual Indicators (Position/Deviation), etc.

Display Inputs could be 4-20 mA OR 0-10 V. The product development involved the electronics as well as the enclosure development. Over 3000 such control stations are operating in the field since the year 2000.

Ace Manufacturing Systems

Application

Keyboard Panel for CNC based Machine Tools. (Machining Centers)

Description

The Keyboard integrates different type of switches – Tactile (snap dome), Push Button, Toggle, Key lock switches, Selector Switches, Rotary Switches, etc. The Panel also included seven segment displays and LEDs.

All the terminations have been brought out on D type connectors having a screw down locking system that can with stand vibrations typical to the shop floor environment. Interfacing circuits comprising of solid state relays have been provided to provide toggle action for switches.

The connectors have also helped to eliminate a complicated individual switch wiring system, resulting in easy assembly and integration of the keyboard panel with the Machine Tool system.

These machining centers are used by most of the top manufacturers in the Automotive Industry like Honda, TVS Suzuki, Bosch, Hyundai, etc.

Moog Motion Controls

Application

Keyboard Panel for Injection Moulding Machines (For making plastic parts) and Blow Moulding Machines (For making plastic bottles)

Description

These keyboard panels are used to interface with the electronics used in controlling the processes in an Injection Moulding Machine. The Microset model comprises of 68 snap dome switches and 48 LEDs. The keyboard interfaces with an Image Display that is mounted behind the keyboard panel. The interfacing circuit is also provided by SBL and the test each switch is tested to ensure that the messages on the display are as per the Quality Assurance Plan (QAP) provided by Moog Motion.

A new model named mPower was introduced with lesser switches, but having the same features like the Microset. SBL continues to supply these panels as of today also.

Over the past 10 years SBL has supplied more than 1000 such panels, which are working successfully on various injection & Blow Moulding Machines all over India.

Windsor Machines

Application
