Silence Sentinel Standard – Analog Silence Detector

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.

Site Sentinel® 4 – Web-based Remote Control

Site Sentinel® 4 – Web-based Remote Control

The Site Sentinel® 4 is a robust, full-featured; web-enabled four channel remote control featuring a desktop/mobile browser compatible web interface (HTML5.) The system is equipped with four metering inputs (0 to 10 VDC), 4 optically-isolated status (logic) inputs, 4 programmable SPST relay outputs which may be configured for ON, OFF and pulsed operation, one temperature probe input, stereo silence sensor, and power failure input. Includes built-in support for email alarms and SNMP.

Smart Relay 4 – Smart GPIO Converter

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

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-4 – Serial GPIO Interface

SRC-4 – Serial GPIO Interface

The SRC-4 interfaces four optically isolated GPI/trigger inputs and four SPDT relay outputs to a RS-232 serial port. The SRC-4 can notify a users PC software program that any of four optically isolated trigger inputs have been opened or closed and allows the users software to control four SPDT relay outputs. Communication with the SRC-4 is accomplished via short “burst” type ASCII commands from the users PC.
