A terminal-input module (TIM) can be used to complete the circuit shown in
figure PT100 in Four-Wire Half-Bridge
(p. 260). Refer to the appendix Signal
Conditioners
(p. 539) for information concerning available TIM modules.

7.8.18.2.3 PT100 in Three-Wire Half-Bridge
Example shows:
• How to measure a PRT in a three-wire half-bridge configuration.
Advantages:
• Uses half as many input channels as four-wire half-bridge.
Disadvantages:
• May not be as accurate as four-wire half-bridge.
