Transmitters suit demanding applications.
Press Release Summary:
Series TX1500 features 2-wire operation power, which is obtained directly from 4 to 20 mA loop, with no need for separate power input. Isolation to 1500 V rms eliminates possibility of electrical ground loops between signal source and receiver. Overvoltage of 120 Vac may be applied across input or output leads for 1 min in all models with voltage or thermocouple input. Reverse polarity of 400 Vp may be applied across output leads indefinitely.

Unmatched Electrical Performance
Two-wire Operation Power is obtained directly from the 4 to
20 mA loop, with no need for separate power input. This simplifies field wiring and eliminates the possibility of noise pickup from power lines.
Isolation to 1500 V rms (2100 Vp)
This exceptionally high CMV rating from the input to the case or output eliminates the possibility of electrical ground loops
between the signal source and the receiver. It also provides a high degree of protection for the receiver against electrical hazards, such as accidental contact between the signal source and an AC power line.
Turndown Ratio
Turndown ratio is defined as zero suppression divided by span. The exceptionally high 10:1 turndown ratio possible with the
TX1500 Series indicates that wide zero offset can be combined with narrow signal span for closed loop control at high gain. The signal span can also be wide for control of batch operations, where a wide range of signal levels may be encountered over the entire batch cycle.
High Overvoltage Protection
Overvoltage of 120 Vac may be applied across the input or
output leads for 1 minute in case of all models with voltage or thermocouple input. Reverse polarity of 400 Vp may be applied across the output leads indefinitely. These exceptionally high NMV overvoltage ratings provide further protection against possible electrical faults and wiring errors.
