The MTL7760AC MTL Instruments Analogue Inputs Low-level Barrier is designed for slidewire displacement transducers. This barrier supplies power and returns a unipolar signal, making it the simplest choice for your applications.

For 3-wire RTDs, the MTL7755ac barrier offers an economical solution for use with floating bridges. The barrier features:

• Low end-to-end resistance of only 19Ω/channel to minimize span changes
• Channels that track within 0.15Ω (between -20°C and +60°C) to minimize zero shift with temperature

For earthed bridge circuits, the MTL7756ac barrier with its third channel is required. For extreme accuracy, three channels with an earth-free bridge configuration can eliminate small errors from barrier leakage.

4-wire constant-current circuits can be protected by two MTL7761ac barriers, or two MTL7755ac barriers if loop resistance increase is a concern.
