A wireless radio remote control is a significant electronic tool used in industrial automation. Literally, this is used to operate huge machines in crane services or other machines. Now the remote control can be contracted to other devices too. This is also know by many others names as well such as converter clicker, button etc. Now commonly remote controls are consumer IR devices that used to issue commands from a distance to gigantic machine or other consumer electronics.

At present, bulk plant wireless emergency shutdown systems are developed to eliminate costly hard wiring of fixed location emergency stop switches. Any number of wirelesses remote E-stop switches within the plant facility and communicate with one receiver and controller unit. This wireless radio remote control system will work in conjunction with existing, hard-wired, manual E-stop switches and plant safety controls. The operator worn E-stop remotes can be also be added to these systems.

E-Stop shut down system transmitter specification:

This is low powered and intrinsically safe devices suitable for use in hazardous environments. The ...
... all systems are CSA, CE, and FCC approved. At the same time, the pressing the Emergency Stop button causes the receiver/controller unit to trigger a plant shut-down.

The system cannot be rebooted until the E-Stop button is pulled out and a manual receiver/controller reset is performed. E-Stop buttons are dual contact with dual channel and comply with global E-Stop switch requirements. The systems will fail safe, triggering an automatic E-Stop with any loss of main line electrical power supply to the receiver/controller unit

This E-Stop Receiver and Controller specifications:

This is easily interfaced with electrical, pneumatic, nitrogen, or mechanical plant shut-off equipment. The systems will operate with 12/24VDC or 120/240VAC power supplies. All receiver and controller outputs can specified as 12/24VdC, 120/240VAC, dry contact, RS232, or J1939 CAN bus.

The standard receiver/controller units are NOT rated explosion proof and are typically installed in non hazardous electrical control equipment areas. Receiver/controller units are provided with antenna and coax cable for outside antenna mounting providing maximum operating range. Explosion-proof electrical enclosures are available on request.

There are some models of bulk plant wireless emergency shutdown system. These are;

MODEL ASKFAX200-AC:

Fixed-frequency remote E-Stop switch operates at 433MHz using two double A batteries. Transmitter is energized only when E-Stop switch is activated. Battery test button shows a low battery flashing LED on the E-Stop switch as well as on the receiver/controller unit. The basic operating range is up to 1000ft.

Daily E-Stop transmitter battery tests and scheduled battery replacement intervals are strongly recommended. The E-Stop transmitters and receiver/controller shut-down will NOT operate when the remote E-Stop transmitter batteries are exhausted.

MODEL DSSF 100-AC:

This wireless industrial remote control has direct sequences; spread-spectrum remote E-Stop switch operates at 2.4GHz using a rechargeable battery pack. The E-Stop switch and receiver/controller unit are connected via Safe Link – a continuous monitoring feature exclusive to BASE Engineering.

Any loss of signal connection between the remote E-Stop switch and receiver/controller results in an automatic E-Stop trigger until the signal is restored. High powered E-Stop transmitters have an operating range of up to two miles. Transmitters must be connected to a back-up power supply as the battery pack will operate for only seven days. The backup power can be 12/24VDC, 120/240VAC, and solar powered where practical.

BASE Engineering designs excellent wireless radio remote control technology for different engineering and commercial purposes. Since 1996 over 50,000 BASE systems have been employed around the globe to increase job safety and productivity. As a result of this design effort we have the confidence to offer a four year, no hassle, and replacement warranty on every wireless industrial remote control we manufacture.
