DS1500 Dewpoint Hygrometer Display Panel mounted. NEW RS485 / MODBUS (RTU) serial communication enabled 4 alarm relays – 2 x change over, 2 x normally open (NO) Compatible with AMT, PDT and AMT-Ex dewpoint transmitters Installed in the safe area unless housed in an Exd Enclosure Panel mounted single channel indicator Process Variable (PV) retransmission in 0-20 mA or 4-20 mA The DS1500 is a digital dewpoint hygrometer display and fully compatible with the Alpha Moisture Systems’ AMT, PDT and AMT-Ex Dewpoint Transmitters for continuous trace moisture measurement in most gases and dry compressed air. The DS1500 system is factory conﬁgured to user speciﬁcation to read in either °C dewpoint, °F dewpoint, ppm(v), ppb(v), g/m³ or lbs/MMSCF. The measured value is displayed on a large six-digit red LED display. DS1500 oﬀers a selectable 0-20 mA or 4-20 mA isolated retransmission signal and four programmable alarm relays. Option For Non-Hazardous Areas Option For Ex Hazardous Areas - See AMT-Ex Datasheet for details. Instrument conﬁguration is achieved from the front keypad, without any hardware change. The selection of input type and alarm modes and other special functions, are also accessed and deﬁned from the front keypad. A digital communication channel is provided via a RS485 (MODBUS RTU Communication Protocol) serial connection for remote interrogation of measured values and status of alarms and instrument.
