4-20mA to LoRaWAN Converters Compared: MacSync LX1 vs Dragino PS-LB-NA vs Milesight UC501 vs SenseCAP S2100

Four devices that put an existing 4–20 mA or 0–10 V transmitter on LoRaWAN® without mains power at the instrument. They differ in how many loops they read, how they power the sensor, the battery they carry, the enclosure and the LoRaWAN class.

Where each fits

What the table means for your site

Where the MacSync LX1 fits

Pressure, level and flow transmitters at tanks, borewells, pipelines and plant rooms in India, where the converter has to power the transmitter and survive outdoors: a 19 Ah battery variant or a 9–36 V DC variant, IP65 with an IP67 option, −40 to +80 °C, and the same hardware reads RS485 Modbus. A MacTalk version links to a MacSet controller with no gateway. Indian manufacture, WPC compliance and support from Pune come with it.

Where the Dragino PS-LB-NA fits

A single current input and a single voltage input with fine resolution, 5 V and 12 V outputs for the sensor and an 8,500 mAh cell, with a solar version. Its page gives no IP rating, so check the manual for an outdoor installation.

Where the Milesight UC501 / UC502 fits

Sites that need more than analog: two switchable analog inputs together with RS232 or RS485, SDI-12 and GPIO, several sensor supply voltages, an IP68 enclosure and NFC configuration. The UC501 runs on rechargeable cells with a solar panel and the UC502 on three 9,000 mAh cells.

Where the SenseCAP S2100 fits

One sensor per logger. The page describes it as a single-channel collector that uses one protocol at a time, chosen from 4–20 mA, 0–10 V, RS485 Modbus RTU or GPIO, on a 19 Ah cell in an IP66 enclosure. The page does not describe a supply output for the sensor.

Questions

Choosing between them

The MacSync LX1 supplies the connected sensor from a selectable power output, with a warm-up time of 0 to 2,000 ms before each reading. The Dragino PS-LB-NA page lists 5 V and 12 V outputs, and the Milesight UC501 / UC502 page lists 3.3 V and switchable 5, 9 and 12 V outputs. The SenseCAP S2100 page checked does not describe a sensor supply output. In every case, compare the output with the transmitter’s minimum supply voltage before ordering.

The MacSync LX1 has two analog channels, each set to 4–20 mA, 0–10 V or digital input. The Milesight UC501 / UC502 has two switchable analog inputs. The Dragino PS-LB-NA has one current input and one voltage input. The SenseCAP S2100 lists two current and two voltage channels, but its page says only one interface type is used at a time.

The MacSync LX1 is designed and manufactured in Pune and is WPC compliant for the IN865 band; support comes from the engineers who built it, in Indian Standard Time. The Dragino, Milesight and Seeed devices are imported, with IN865 versions available.

With care, because the sensor usually uses more energy than the radio. The Dragino page says up to 5 years and the SenseCAP page up to 10 years, without the conditions. A transmitter that needs a long warm-up or a short reporting interval shortens any of these figures. Ask each supplier for an estimate with your transmitter model and interval; Macnman provides one for the MacSync LX1 on request.
