1 Wireless I/O Module WM11 Datasheet OVERVIEW The WM11 provides long-distance wireless connectivity to reduce the cost of wiring sensors and equipment in hard to reach places. With a range of over 300m in open-air settings, the built-in analog and digital IO capture and transmit data directly to the Samsara IG41 Industrial Controller where it is automatically uploaded to the Samsara cloud. The WM11 is battery powered, IP66-rated, and mounts easily on industrial equipment for rapid deployment. Lower costs and save time by elminating wiring, and bring visibility to industrial equipment no matter the location. HIGHLIGHTS Long range wireless 300m+ open air range for industry-standard analog and digital sensors Analog & digital IO Connects up to 4 analog inputs, 1 digital input, 1 digital output Ruggedized Rugged, IP66-rated enclosure Low power Low power consumption with consumption field replaceable batteries or optional external power TENTATIVE 2 WM11 Wireless Module ENCLOSURE Dimensions (WxHxD) 93mm x 124mm x 65mm Weight 400 g Mounting Four mounting ears, M5 (#10) ENVIRONMENTAL Operating temperature -40°C to +75°C (-40°F to +167°F) Storage temperature -40°C to +85°C (-40°F to +185°F) Operating humidity 10% RH to 90% RH, noncondensing Ingress protection IP66 POWER Battery life 2 years with 1 poll per hour Batteries Two 3.6-V 2500-mAH lithium AA batteries External power (optional) 9 ~ 36 VDC SHOCK & VIBRATION Free fall IEC 60068-2-32 Operating shock IEC 60068-2-27 Operating vibration IEC 60068-2-6 CONNECTIVITY Protocol LoRaWAN Range 300m+ in open air Polling interval Configurable from 20s to one day TENTATIVE 3 WM11 Wireless Module ANALOG INPUTS Number of inputs 4 Configuration 2 AI voltage, 2 AI current Input range 0-10V, 0-20mA Resolution 16 bit Input load resistance 10 MΩ (voltage), 120 Ω (current) Accuracy ±0.1% (Voltage) at 25 °C ±0.2% (Current) at 25 °C” DIGITAL INPUTS Number of inputs 1 Voltage range Dry contact : Logic level 0: close to GND, Logic level 1: open Wet contact : Logic level 0: 0 ~ 1 VDC, Logic level 1: 3 ~ 30 VDC Pull-up current 32 μA Input high voltage 2.0 V min Input low voltage 0.8 V max Isolation None Channels 2ch DIGITAL OUTPUTS Number of outputs 1 Voltage range 0-30 V Output type Open drain Output current 100 mA max Protection Current limit protection Isolation None TENTATIVE 4 WM11 Wireless Module SAFETY, HAZARDOUS LOCATIONS, & COMPLIANCE* Hazardous locations US (UL) • Class I, Division 2, Groups A, B, C, D, T4 • Class I, Zone 2, AEx nA IIC T4 Electromagnetic compatibility • FCC 47 CFR Part 15B, Class A • ICES-003:2016 Issue 6 (ITE) Class A • ANSI C63.4:2014 • EN 61000-4-2:2009 / IEC 61000-4-2:2008 ED. 2.0 • EN 61000-4-3:2006 +A1:2008 +A2:2010 / IEC 61000-4-3:2010 ED. 3.2 • EN 61000-4-4:2012 / IEC 61000-4-4:2012 ED. 3.0 • EN 61000-4-5:2014 +A1:2017 / IEC 61000-4-5:2014 +A1:2017 ED. 3.0 • EN 61000-4-6:2014 +AC:2015 / IEC 61000-4-6:2013 ED. 4.0 • EN 61000-4-8:2010 / IEC 61000-4-8:2009 ED. 2.0 Note: In the United States (per FCC 47 CFR), Class A equipment is intended for use in commercial, light-industrial, and heavy-industrial locations.

These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one of the following measures: • Reorient or relocate the receiving antenna • Increase the separation between the equipment and receiver • Connect the equipment into an outlet on a circuit different from that to which the receiver is connected • Consult the dealer or an experienced radio/TV technician for help FCC Caution: Any changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate this equipment. This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. FCC Caution: Any changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate this equipment. IMPORTANT NOTE FCC Radiation Exposure Statement This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment. This equipment should be installed and operated with minimum distance 20cm between the radiator & your body. This transmitter must not be co-located or operating in conjunction with any other antenna or transmitter. TENTATIVE
