MAIN FEATURES:

Programmable and modular inputs, supporting multiple input types of thermocouples, RTDs, voltage/current
and two-wire transmitters. Suitable for measuring and displaying temperature, pressure, flow, level, humidity,
etc with measurement accuracy of 0.3% full scale.
Dual display windows, convenient to set parameters and alarm points. Various dimensions are selectable.
Supports up to 4 loops of alarms including 2 loops of high limit alarms plus 2 loops of low limit alarms.
Alarms can be outputted to different relays or share one.
With functions of digital calibrating, digital filtering, and thermocouple cold junction auto compensating, it is
free of maintenance and easy operated.
Supports RS485 communication interface, able to communicate with computers.
Retransmission function, cooperating with X3 high precision current output module (0.2%FS), can
retransmit temperature with accuracy of 0.3%FS.
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.
