RKI M2A™ LEL Combustibles Sensor/Transmitter, 0 to 100%, Low-Mount
Description
- Operates with or without a controller
- Features 4-20 mA and digital Modbus outputs
- Suitable for explosion-proof environments
State-of-the-art RKI M2A sensor/transmitters operate as independent, standalone detector heads for specific gases or as part of an integrated system. They feature both a 4-20 mA and Modbus output to send target gas readings to nearly any PLC, DCS or controller—including RKI Beacon 200 or 410A controllers. Three sets of relay contacts (two controlled by gas alarms and one by a fail alarm) trigger devices such as lights or horns.
User-friendly pushbuttons and menus make setup and operation simple. A viewing window on the cover lets you view gas concentration on the OLED display, along with alarm and status lights. A magnetic wand accessory activates switches through the window for easy, nonintrusive zeroing and calibration—conduct a complete field calibration with just one person. An Auto Zero drift-correction feature stabilizes readings and minimizes manual adjustments as sensors age.
This unit is configured for low-mount applications (up to 10 feet).
Includes: magnetic calibration wand. A calibration cup is required but not included; order stock # 332642 separately.
- Alarm settings: two programmable setpoints, increasing/decreasing, latching/self-resetting, on and off delays, normally energized or de-energized
- Visual alarms: LEDs for alarm 1 (amber), alarm 2 (red) and fail (red)
- Alarm relays: 5A Form C contacts for alarm 1, alarm 2 and fail
- Analog output: 4-20 mA signal, into 1000 Ω impedance max (24 DC), 0 to 500 Ω max (12 VDC) corresponding to 0 to full scale
- Digital output: Modbus RTU, 2-wire RS-485, 1200 to 19.2k baud
- Power: 10-30 VDC
- Enclosure: NEMA 4X, explosion-proof, watertight, cast aluminum with O-ring seal and epoxy powder coating
- Operating conditions: -40 to 122°F; 5 to 95% RH noncondensing
- Dimensions (H x W x D): 8.5" x 5.2" x 4.5"
- Sensor compliance: Class I, Div. 1, Groups B-D explosion-proof
