E2S Warning Signals LED upgrades

E2S Warning Signals has upgraded its B350TLA traffic light-style warning signal beacons. They feature a compact 100 x 140 mm housing, suitable for space-constrained applications or for mounting directly onto machinery. The larger 140 x 177 mm B450TLA units have also been upgraded. The light engine for both is an array of 18 high-output white LEDs, which give bright outputs up to 356 candela. The ultrasonic-welded diffused lens determines the output light colour: amber, blue, clear, green, red and yellow are standard, enabling on-site reconfiguration of colours and greater flexibility in inventory management. There are now seven flash patterns, including a temporal pattern for greater effectiveness, in addition to a steady output for status indication.

The included connector enables multiple units to be assembled into stacks and dual-pluggable terminals simplify cable installation for looped installations. The operating voltage are ranges are 10–14 VDC, 16–33 VDC and 48–260 VAC/DC. The 1 Hz flash operating current is only 88 mA at 24 VDC and the operating temperature is -40 to +70°C.

Also upgraded with the latest 18 white LED array light source are the STA and STB ranges of customisable stack signals, UL-approved for general signalling applications such as status indication, security and process control. The STA stacks have an SONF1 compact 100 dB(A) alarm horn sounder to give an integrated audible/visual unit.
