Paperless Recorder 7-Inch Multi-Channel Industrial-Grade Chart Recorder Temperature Data Logger

The GT71R supports up to 16 channels of fully isolated universal analog inputs. It can process Voltage 0-5V,1-5V,0-100MV , Current 4-20MA,0-20MA, RTDs (Pt100, Cu50, Cu53), and Thermocouples (K, S, R, B, E, J, T, N, etc.). Each channel uses a high-speed 32-bit ARM processor to ensure 0.2% F.S. accuracy across all signals.

Yes. Beyond simple data logging, the GT71R supports optional PID control functions. It can provide up to 4 channels of standard current output (4-20mA) and up to 6 relay alarm outputs. This makes it a highly integrated solution for both data recording and automatic process control.

The GT71R is designed to simplify your field wiring by supporting up to 3 sets of isolated 24VDC Distribution outputs. Each group can provide up to 60mA, which is sufficient to power multiple 2-wire pressure, flow, or level transmitters without requiring an external power supply.

The unit offers flexible storage options from 64MB to 248MB Flash memory (storing up to 900,000+ records). For remote monitoring, it supports RS485/RS232 (Modbus RTU protocol) as standard and offers Ethernet (RJ45) as a custom function for integration into SCADA or cloud-based data management systems.

The GT71R features a 7-inch true-color TFT LCD (800*480 matrix) with adjustable display configurations (Bar graphs, Real-time curves, Historical curves). It operates reliably in temperatures from 0 degree centigrade to 50 degree centigrade and is built with a "short thickness" design for space-constrained panels. The built-in hardware clock and non-volatile memory ensure permanent data protection even after power failure.
