Silence Sentinel RJ – Analog Silence Detector

The Silence Sentinel® RJ is designed to monitor any two stereo analog audio sources for silence or an out of phase condition (polarity), generate alarms, and transparently switch to a back-up source using mechanically latching relays.

Silence Sentinel Standard – Analog Silence Detector

The Silence Sentinel® Standard is designed to monitor any two stereo analog audio sources for silence or an out of phase condition, polarity, generate alarms and transparently switch to a back-up source using mechanically latching relays.

Silence Sentinel® Basic – Analog Silence Detector

The Silence Sentinel® Basic is a simple stereo/dual mono analog silence sensor designed to monitor any stereo or two independent monaural sources and generate alarms when silence is detected, it does not include an audio switcher.

Smart Relay 4 – Smart GPIO Converter

The Smart Relay 4 is a perfect tool for converting sustained network contact closures to pulses or applying logic/timing functions. The Smart Relay 4 provides four independent DPDT relay outputs and eight optically isolated wet or dry inputs. User programmable logic and pulse stretching (delays) may be set from 50 ms to 99 hours, 59 minute and 59.99 seconds.

SRC-16 – Serial Remote Control

Connection through an RS-232, RS-422 or RS-485 serial port with baud rates up to 38400 the SRC-16 can notify your PC software program that any of 16 optically isolated inputs has been opened or closed and allows your software to control sixteen SPDT, 1-amp relays.

SRC-16 Plus – Serial GPIO Interface

The SRC-16 Plus is connected through an RS-232 or RS-422/485 serial port and can notify your PC software program of GPI/trigger inputs on 16 optically isolated inputs and allows your software to control any of the 16 SPDT, 1-amp relay outputs.
