Danger and warning!
This device can be installed only by professionals.
The manufacturer shall not be held responsible for any accident caused by the
failure to comply with the instructions in this manual.
Risks of electric shocks, burning, or explosion
This device can be installed and maintained only by qualified people.
Before operating the device, isolate the voltage input and power supply and
short-circuit the secondary windings of all current transformers.
Use appropriate voltage tester to make sure the voltage has been cut-off.
Put all mechanical parts, doors, or covers in their original positions before
energizing the device.
Always supply the device with the correct working voltage during its operation.
Failure to take these preventive measures could cause damage to equipment or
injuries to people.

Chapter 1 Product Overview
PBAT61 battery cell sensor is specially designed as highly integrated smart
sensor module for VRLA batteries, can quickly and accurately measure the
VRLA’s voltage, resistance and negative pole temperature. Cell sensors use
specified isolated communication bus, and multiple sensors can be very easily
cascaded to realize the real-time monitoring of the entire strings of batteries.
The cell sensor can fulfill following functions:
Measurement of real-time voltage
Measurement of Internal resistance on line
Measurement of negative pole temperature
Sleep mode to achieve ultra-low standby power consumption
Built-in anti-reverse in put circuit aims to protect the sensor and
battery away from damage even if the power supply is connected
conversely.
Built-in fuse with high reliability and safety
Communication interface’s isolation voltage is AC 3750V
Wiring easily with distributed installation
One PBAT-Gate can support up to 240 cell sensors by cascade
Passive balancing function, the balancing current up to 200mA

DL-BUS communication，RJ11 interface
8
COM2b
DL-BUS communication，RJ11 interface
Note:
a. The cell sensor uses four-line method to measure the internal
resistance of VRLA.‘V+ Sense’ and ‘V- Sense’ need to be connected
directly with the battery pole. In order to obtain proper measurement
accuracy described in this document, the users should use the
standard factory wire especially for measurement.
b. COM1 connect to the previous node, COM2 connect to the next
node.
