• Supports up to 4 loops of alarm including 2 loops of high limit alarms plus 2 loops of low limit alarms. Alarms can be outputted to different relay or share one.
• With functions of digital calibrating, digital filtering, and thermocouple cold junction auto compensating, it si fee of maintenance and easy operated.
• Supports RS485 communication interface, able to communicate with computers/PLC.
• Temperature retransmission at combined accuracy 0.5% FS through X3 (0.2%FS) high precision current output module.
• High quality and performance hardware design, using high performance tantalum capacitor or ceramic capacitor. Compared to competing models, it consumes less electricity, experiences less temperature shifting, provides higher stability and reliability and can work in a wider range of temperature. The power and I/O terminals have passed the anti-interference test of 4KV/5KHz burst of pulses.
• Universal 100-240V power supply, with thunderbolt proof and 10 seconds protection from connecting to 380VAC by mistake.
