Product Introduction

overview

The NHR-5610 series heat accumulation controller collects, displays, controls, transmits, communicates, prints and processes various signals such as temperature and flow on site, forming a digital acquisition system and control system. It is suitable for heating systems and heat exchange systems such as water and heating, and realizes online measurement of heat and mass transfer, providing a basis for enterprise energy management, energy consumption measurement, and technical economy.
Dual screen LED digital display, with an extremely wide display measurement range, can display five digit instantaneous flow measurement values, inlet/outlet temperature measurement values, flow (differential pressure, frequency) measurement values, and eleven digit cumulative flow measurement values, with a measurement accuracy of 0.2% and a cumulative accuracy of 0.1%.
It has 37 signal input functions and can be matched with various differential pressure signals (orifice devices), linear signals (electromagnetic flow meters), and pulse signals (vortex flow meters).
Simple fault-tolerant function: When the inlet and outlet temperature measurement signals are abnormal, compensate with the corresponding manually set values.
Specially designed WDT circuit, power on reset circuit, and power-off data protection circuit ensure the normal operation of the instrument when powered on; Built in 33V dry battery, data is not lost in case of power failure, no backup power supply is needed for power failure data protection, and the protection time is not less than 3 years.
Can carry two analog transmission outputs.
Supports RS485 and RS232 serial interfaces, using standard MODBUS RTU communication protocol.
The instrument can be equipped with RS232C printing function, with manual, timed, and alarm printing functions.
Equipped with DC24V power supply output for on-site transmitter power distribution.
Optoelectronic isolation technology is used between input, output, power supply, and communication.
Parameter setting password lock, parameter settings are permanently saved when powered off, and have the function of restoring factory settings.

		⑾ Remarks

remarks:

1. When selecting, please refer to the wiring diagram to choose the function. Due to the small size of instrument wiring terminals, they may not have full functionality, and some functions can only be selected from one of them on the same group of terminals.
2. When writing the model, it must be complete, and any function items that have not been selected cannot be omitted and must be supplemented with an "X".
Example 1: NHR-5610A-27/27/27-0/X/2/X/X-A
Example 2: NHR-5610B-14/27/27-0/X/2/D1/X-A
3. The input type of the flow channel is only selected as voltage, current, or pulse input, with pulse input only selected for the flow channel.
4. When the pulse signal is input, the instrument cannot select the second transmission output.
