SEM1636 (4 to 20) mA LOOP POWERED DUAL TRIP AMPLIFIER 

## **DUAL INDEPENDENT RELAY OUTPUT** 

**FAIL-ON OR FAIL-OFF RELAY ACTIONS** 

**FILTER AND USER-LINEARISATION FUNCTIONS** 

**PC CONFIGURATION USING USB PORT** ~~KO~~ **LIVE DATA CAN BE VIEWED ON AN ANDROID** > **PHONE OR TABLET** 

## **INTRODUCTION** 

The SEM1636 monitors a (4 to 20) mA loop and provides two independent change-over trip contacts set to alarm at any point within the (4 to 20) mA range. The SEM1636 requires no additional power connection as power is derived from the (4 to 20) mA loop. Relay outputs are independently configured for action and set-point, dead-band. Six actions are provided: normal, High/Low/Deviation and inverted High/Low/Deviation. Additional maths, filter and userlinearisation functions are provided. 

## **FEATURE HIGHLIGHTS** 

## **ALARM OPTIONS** 

Both relays are independently settable with multiple alarm options. High, low, inverted and deviation band alarms are available with set-point and dead-band adjustment. 

## **MATHS FUNCTIONS** 

The SEM1636 in addition to input scaling, has power and root functions, as well as a 22-point userlinearisation tool. 

## **LED INDICATION** 

Relay 1 and Relay 2 each have an alarm indication LED on the front of the device. 

## **LOW POWER** 

Powered from the (4 to 20) mA loop with a voltage burden of less than 5 volts. 

## **USB PC CONFIGURATION** 

The SEM1636 is quick and easy to configure using a standard-type USB lead and the free-of-charge USBSpeedLink Windows software. 

## **USB ANDROID VIEW** 

The SEM1636 can be connected to an android phone or tablet using an OTG USB adaptor. Running a free App the Android device can then be used to view live data from the SEM1636
