Wireless Smart Datalogger Electric Energy Consumption Technical Information ** Power supply 7.7A/h - 3.6V type "C" lithium internal battery Battery life (battery life depends by datalogger's working conditions) 5 years (typical, samples every 10 minutes) Measures acquired (2 channels) Pulses coming from clean contact or open collector: ^ CH1: single-phase/three-phase active energy ^ CH2: single-phase/three-phase reactive energy Compatible with any energy counter provided with pulse digital output Count weight Selectable onboard: Values are modifiable through multipliers to be inserted by software Sampling interval Selectable from one minute to seven days* Datalogger capacity 128,000 measures per channel Radio range 300m on sight Mounting fix on 4 points (hole 0 5mm) External wire diameter 4.7mm maximum Copper wire section 0.05*2.5mm2 / * 14 AWG Optional accessories* ^ Electric energy counters ^ Flexible Rogowski coils ^ Open/closed TA (amperometric transformers) ^ POD counter pulse acquiring interface (EXP2PUL) Two Channels Wireless Smart Datalogger Datalogger for electric energy consumption (active energy/reactive energy) acquisition. Each channel is a digital input for a clean contact or open collector capable to count pulses coming from energy meters. The radio module based on WINECAP™ protocol provides an excellent radio range and a very low battery consumption. With a backup memory onboard may store the last 128,000 samples per channel even if the wireless link is down that can be downloaded using a USB connection. Using the configuration software the sampling interval may be set and two thresholds per channel can be activated. May be interfaced with: • all the basestations of MWDG product line • all the basestations of MWLI product line If necessary, radio range may be extended using up to 32 WR11 routers (maximum 16 for each path) between the datalogger and the basestation. Pulse input - Connection Internal clamp terminal Pulse input - Sensor input from 0 to 4.5mm 0 gland Pulse input - Maximum count frequency 25Hz with pulse time set to 20msec * Minimum interval depends on the number of dataloggers enrolled in the network The features shown may be subject to change without notice.
