The N4DSC08 is a new version of the 8-channel RS485 temperature logger. It features several upgrades to accommodate a wider range of DS18B20 sensors of varying lengths and manufacturers. It's an ideal DS18B20 adapter.

Working voltage: Power Supply DC 7-25V;
Working current: 11-18MA
Number of acquisition channels: 8 channels
MODBUS RTU protocol, 03, 04 read commands, 06, 16 write commands.
Serial port baud rate: 9600 (default), 1200-115200,N, 8, 1
By modifying the RS485 address, up to 247 modules can be cascaded (more than 16 please use R485 repeater)
Adapted sensor: DS18B20 Temperature Sensor
Temperature measurement range: -55°C to +125°C(-67°F to +257°F)
Size: 75 *50 * 14mm(Only Board),80 *54 * 26mm(With DIN housing)
Weight: 36g(Only Board) ,66g(With DIN housing)

In order to collect temperature more stably, it is recommended that the cable length of the DS18B20 probe should not exceed 15 meters.
1 For probes less than or equal to 5 meters, the default settings can be used
2 When the probe cable is greater than 5 meters, data can be collected correctly under normal circumstances. However, some manufacturers' sensors are incompatible and cannot collect data correctly.
The following modifications can be made:
1 Set the 0X00F3 register to 1.
2 Change the RA1/RA2 resistor to 3.9K or 2.7K resistor.
