Description The TMZ PC-Programmable MODBUS Temperature Transmitter and Signal Converter accepts a single or dual direct signal inputs from a wide array of sensors and analog devices: RTD • Thermocouple • Current • Voltage Millivolt • Ohms • Resistance • Potentiometer Analog-to-MODBUS Conversion The 4-wire (line/mains-powered) TMZ converts the inputs to the standard MODBUS RTU (RS-485) communication protocol ready for direct interface with MODBUS-based monitoring and control systems. Save Wiring and Installation Costs When monitoring points are dispersed, or in small clusters, the TMZ is the ideal solution for collecting and concentrating them onto a single MODBUS RTU communication link. Up to 32 TMZs (without repeaters) can be multidropped onto a single low-cost communication link (such as a twisted wire pair). This eliminates the need to run a dedicated wire for each signal, and delivers significant savings on installation, cable, conduit, connection and wire tray costs. Figure 1. Available TMZ models deliver versatile input and output options. Single or Dual Programmable Inputs RTD T/C Ohms Pot mV mA V Certifications f £ CE Conformant - EMC Directive 2014/30/EU - Features • 20-bit input resolution delivers exceptional digital measurement accuracy. The TMZ delivers accuracy of ±0.1 °C (±0.18°F) with all platinum RTDs, or ±0.01% of maximum span with current and voltage inputs. • Increase density and reduce costs. The Dual Universal Input (2PRG) model accepts two inputs where each input can be configured for current, voltage, RTD, Thermocouple, mV, Potentiometer or Resistance, doubling your monitoring capability in a single unit. • Output error is eliminated. Since the measurement is delivered to your control system as a digital signal, the output error produced by a traditional analog transmitter is eliminated. • PC-programmable with Windows® software. From a single screen, you can choose, and then view to confirm, all of your application specific operating parameters from a PC. • Long-term stability. Allows up to 5 years between scheduled calibrations. • Isolated and RFI/EMI protection. Delivers superior protection against the effects of ground loops, plant noise, radio frequency and electromagnetic interference.

Figure 2. Up to 32 TMZs, without repeaters, can be multidropped onto a single MODBUS RTU communication link. The TMZ can be installed on the same data link with standard MODBUS RTU devices including Moore Industries' NCS NET Concentrator® Process Control and Distributed I/O System (shown below). Any combination of TMZ configurations may be connected in the same system. One Window. One Minute. One Setup. All operating parameters configure quickly and easily using our Intelligent PC Configuration Software. Programmable functions include: • Input type and measurement range (zero and full scale...

PC-Programmable MODBUS Temperature Transmitter and Signal Converter Trim to Specific Curve Segments The TMZ can be trimmed with two data points within the selected zero and span measurement range. This allows a complete process range to be monitored, while placing measurement emphasis on a critical segment of the range. In the figure below, the ideal RTD curve is optimized between 20°C and 27°C to match the curve of the sensor used. This provides incredible precision over a limited portion of the span, while measuring the remainder of the span with outstanding accuracy. The TMZ (Single...

TMZ PC-Programmable MODBUS Temperature Transmitter and Signal Converter Performance Input Accuracy: Current ±2 microamps; Voltage ±1mV Overall Accuracy: The overall accuracy of the unit is the input accuracy. It includes the combined effects of linearity, hysteresis, repeatability and adjustment resolution. Stability: See Table 1 Response Time: INPUT UPDATE TIME: 128msec; MODBUS POLLING TIME: Dependent upon how fast and how often a MODBUS master requests data Isolation: DUAL INPUT AND SINGLE INPUT (WITH -RF) : 500Vrms between case and input; input to MODBUS; power to case and power to...

TMZ PC-Programmable MODBUS Temperature Transmitter and Signal Converter Performance Input Accuracy: See Table 5 Overall Accuracy: The overall accuracy of the unit is the input accuracy. It includes the combined effects of linearity, hysteresis, repeatability and adjustment resolution. It does not include ambient temperature effect. For T/C input, add the RJC error. Reference Junction Compensation Accuracy (T/C Inputs Only): ±0.65°C Stability: See Table 2 Response Time: INPUT UPDATE TIME: 128msec; MODBUS POLLING TIME: Dependent upon how fast and how often a MODBUS master requests data...
