Description

A heat sensor rated 58 °C and Rate of Rise, this S200A device carries the Type A1R classification and a white finish. Its rate of rise temperature sensing is analogue addressable, built on low mass thermistors and microprocessor technology so that response stays fast, and the sensor works to the System Sensor Protocol.

Mounting is on the B501AP base, the B501AP ANALOGUE SENSOR BASE, which this sensor requires. Installed weight is 88g (inc base), with a height of 61mm and 102mm across. The PC/ABS moulding is White and terminals will accept 2.5mm² conductors. Standby is 200 µA at 24Vdc in the absence of communications and 300 µA at 24Vdc with the blink LED running once every 5s, while LED current is 3.5mA at 24Vdc.

Read the full technical description

The 52051RE-26 is an S200A analogue addressable heat sensor rated 58 °C and Rate of Rise, classified Type A1R and finished in white. Low mass thermistors and microprocessor technology give the rate of rise temperature sensor its fast response, and a B501AP analogue sensor base is required to mount it.

The sensor answers as one of the System Sensor Protocol Analogue Addressable Field Devices. Supply is anywhere from 15 to 32Vdc. In standby the sensor needs 200 µA at 24Vdc without communications taking place, climbing to 300 µA at 24Vdc when the LED blink option runs once every 5s, and the LED draws 3.5mA at 24Vdc.

The moulding is PC/ABS in White. With the base fitted the sensor weighs 88g (inc base), height is 61mm and diameter 102mm, cable of up to 2.5mm² can be landed at the terminals, and the operating envelope runs -30°C to +70°C with relative humidity from 10 to 93% (non-condensing).
