Long Range Wireless E-Stop - 900 MHz

Description

With our 900 MHz, Long Range mesh remote control, you can control up to 6 pieces of equipment from up to 4000 feet in real-time with one wireless emergency stop transmitter or a combination of six transmitters and receivers. This combination allows you to set one transmitter to one receiver, five transmitters to one receiver, or three transmitters to three receivers for multiple operators and multiple equipment use.

They are designed to meet the rigorous requirements
for Safety Integrity Level (SIL) 2 based on the IEC61508 standard.

Our wireless emergency stop system starts with a receiver with two independent solid-state sourcing outputs rated for 5A each.

The first output is normally ON and turns OFF in an E-Stop condition. It’s reset to an ON condition when the E-Stop switch is returned to neutral/safe.

The second output is normally ON and turns OFF in an E-Stop condition but requires recycling machine power after returning to a safe position to clear the output. The mobile DC receiver takes 9 – 30VDC and is epoxy-potted for total protection. The Industrial receiver was designed with two from A relays rated at 6A each and comes with a 110-240 VAC power supply.

Because the name of the game is safety
Redundancies are at both the transmitter and receiver.

The transmitter uses two normally closed switches wired in series for redundant protection, and the receiver uses the third output to activate the two main outputs. We then offer a choice of four different transmitters –

1. 1. Small pocket-clip wireless emergency stop switch that’s vertically actuated,
  2. Larger, belt-worn wireless E-Stop switch that’s vertically actuated, and
  3. Horizontally actuated wireless kill switch, and
  4. Wall-mount unit.

Important to note: these are all two-way radios in a mesh configuration so that the operator has a real-time indication of machine issues and radio link-status!
