Sensidyne, LP Explosion-Proof Transmitter 7013377

Adding Alarm Relays and RS-485 Output to the SensAlert ® Universal Transmitter opens up many new applications and integration possibilities. The serial output uses Modbus RTU protocol, and a 4-20 mA output is also provided, in addition to three SPDT alarm relays. The expanded user interface (MMI) is magnetic, and functional testing, calibration and alarm setting are menu driven. The LCD display is used to lead the user through all functions, in addition to normally indicating the value, measuring units, and gas name. Three LEDs are provided for alarm annunciation. The Digital transmitter is approved for Class I, Divisions 1 and 2, using optional enclosures. Integrating a large number of transmitters can be achieved by using a multi-drop loop, connecting up to 128 units with two or four wires, plus the required 24 VDC power wiring. Accessories, including duct mount, sample draw equipment, and remote sensor kits provide maximum application flexibility.
