Product Description
Technical Specifications (Temperature Controller)
10.1-inch color TFT touch LCD or 7-inch color TFT touch LCD
There are four basic display screens: digital display, bar graph display, real-time curve display, and historical curve display. The basic measurement error is less than ±0.2% of full scale, and the digital display range is –999.99 to 1999.99.
Measurement resolution: 1/60,000, 24-bit ADC
The real-time curve recording interval ranges from 1 second to 9,999 seconds, corresponding to a full-screen curve duration of 30 seconds to 300 minutes.
The recording interval of the memory curve can be continuously set from 1 second to 9,999 seconds. Relay output: contact rating is AC 220 V, 3 A; for resistive loads, the load resistance must exceed 2 kΩ. Sixteen output channels are user‑configurable and can be programmed according to the alarm threshold values of each channel. Voltage output impedance: —. DC 24 V power supply: used to power the transmitter, with a maximum current capacity of ≤200 mA.
·Optoelectronic isolation
Standard configuration includes RS232 and RS485 communication; Ethernet communication requires specifying the baud rate—9600, 19200, 57600, or 115200—at the time of order, selectable via settings. · Comes with dedicated test software, providing parameter‑setting tools and application‑level technical support.
·Optional Modbus RTU communication protocol for communication with the host computer
Instruments powered by AC 220 V: AC 85–265 V, with power consumption less than 25 VA. Instruments powered by DC 24 V: 24 V ±10%, with power consumption less than 25 VA. Note: Actual power consumption depends on the total number of channels of the instrument.
Operating temperature range: 0°C to 50°C
Storage temperature range: -20°C to 70°C
Operating humidity range: below 85% RH, no condensation.
Instrument weight (64 channels): approximately 3.8 kg max.
