Triple relay outputs to control large valve, small valve and pump for anti-overshoot dosing
8 groups preset common batch values, one-click recall for repeated production formulas
Complete data storage: saves batch logs, power-down records with permanent memory retention
Multiple communication options: RS485, RS232 and Ethernet, Modbus RTU supported
Built-in thermal printer interface to print batch data and production reports on site
Multi-unit switching (L/m³/kg/t), supports liquid density & temperature mass conversion
Independent start/pause/reset external terminals for convenient cabinet operation
Multi-level password protection for parameter setting, calibration and total data reset

Specification of XSJ Batch Controller

Item Name	Technical Parameters
Input Signal	Analog input		Pulse input
	Thermocouples: Standard thermocouples—K, E, B, J, N, T, S;		Waveforms: rectangular, sine, and triangular waves
	Resistance: Standard resistance temperature detector (RTD) – Pt100;		Amplitude: Greater than 4V;
	Current: 0～10mA, 4～20mA ——Input impedance ≤250Ω		Frequency: 0-10KHz (or as required by the user).
Output Signal	Analog output	Communication output	Digital output	Power supply output
	DC 0～10mA (load resistance ≤750Ω)	Interface methods – Standard serial interfaces: RS-232C, RS-485, Ethernet;	Relay output – with hysteresis.	DC24V, load ≤100mA;
	DC 4～20mA (load resistance ≤500Ω)	Baud rate – 600, 1200, 2400, 4800, 9600Kbps, internal instrument setting, 8 data bits, 1 start bit, 1 stop bit.	A C220V/3A; DC24V/6A (Resistive load)	DC12V, load ≤200mA
Display Content	• Large 128×64 dot matrix LCD graphic display with backlight; • Cumulative flow rate • Instantaneous flow rate • Cumulative heat • Instantaneous heat • Medium temperature • Medium pressure • Medium density • Medium enthalpy • Flow rate (differential pressure current, frequency) value • Clock • Alarm status;
Control/Alarm	• Selectable upper and lower limit control (or alarm) outputs via relays, with LCD and LED output indicators; • Control (or alarm) mode with hysteresis (user-configurable; the number of alarm relays is selected by the user during ordering, with a maximum of two); • Alarm modes selectable: upper flow limit, lower flow limit, upper temperature limit, lower temperature limit, upper pressure limit, lower pressure limit;
Printing Control	By connecting a serial thermal Chinese character printer via the RS-232 interface, instant or scheduled printing can be achieved; parameter settings: up to 8 scheduled printing times per day, printer soft switch.
Interface Display	Display in Chinese
Protection Methods	• Accumulated value retention time after power failure is greater than 20 years; • Automatic reset when power is undervoltage; • Automatic reset for abnormal operation (Watch Dog); • Self-resetting fuse for short circuit protection.
	The software provides digital password protection for important data. Parameters set by professional engineers effectively protect against unauthorized alterations and, in commercial applications, prevent end-users from intentionally modifying instrument parameters.
Usage Environment	Ambient temperature: -20～60℃; Relative humidity: ≤85%RH; Avoid strong corrosive gases.
Power Supply	Standard type: AC 220V (50Hz±2Hz); Special type: AC 80～265V — switching power supply; DC 24V ±1V — switching power supply; (AC 36V 50Hz±2Hz) Backup power supply: +12V, 20A H, can last for 72 hours.
Power Consumption	≤10W
