The PVW voice synthesizer horn speakers, available from Patlite Signal/JTEC , are suitable for noisy environments and have the capacity to replay a message up to 64 seconds long. The anticorrosive stainless steel brackets meet IP-53 for wash down requirements.
15 messages of up to 64 seconds each can be set on the horn speakers, and played back with clear sounds due to the high bit rate (ADPCM 64kbit/s). High volume (max. 105dB at 1m) replay is available via the optional extension amplifier to connect with the AUX OUT output. Volume can also easily be adjusted by the operator using the internal rheostat to match a range of environments and application conditions.
The horn speakers feature a NPN open-collector that enables direct connection to a PLC. The playback start signal is input from a switch on an external device. If the signal is received once, the message will be played once, and if the signal is continued, it will be repeated.
