Voltage

RTD TRANSMITTER

(CE, non-isolated)

Functions & Features

• Accepting direct input from an RTD and providing a

standard process signal

• Linearization

• Burnout protection

• "Active bridge" circuit containing two constant current

sources allows large leadwire resistances up to 200 Ω

• High density mounting

1: 0 – 10 mV DC (Load resistance 10 kΩ min.)

2: 0 – 100 mV DC (Load resistance 100 kΩ min.)

3: 0 – 1 V DC (Load resistance 3000 Ω min.)

4: 0 – 10 V DC (Load resistance 10 kΩ min.)

5: 0 – 5 V DC (Load resistance 5000 Ω min.)

6: 1 – 5 V DC (Load resistance 5000 Ω min.)

0: Specify voltage (See OUTPUT SPECIFICATIONS)

Typical Applications

• Long distance transmission between the RTD and the

transmitter

• Combination with intrinsic safety barriers
