The H CableFast cabling block is used for analog inputs, with individual fusing provided per channel. This interface provides plus, minus, shield, and power supply interface for both field and loop power configurations.
The following figure shows the 140 CFH 008 00 terminal block.
The following are the application notes for the 140 CFH 008 00 module.
-
Configuration – eight analog inputs with a common loop supply. Each point is allocated four terminals.
-
Compatibility – this terminal block provides individually 0.063 A fused connection point sets for the 140 ACI 030 00 and 140 AVI 030 00 analog input modules.
The following figures show the dimensions for the 140 CFH 008 00 module.
Wiring Diagram (Source Grounding)
The following figure shows the wiring for the 140 CFH 008 00 (source grounding) module.
NOTE:
-
When using a single power supply, there will be no channel-to-channel isolation of input points.
-
For the required jumper options for the 140 ACI 030 00 and the 140 AVI 030 00, see the wiring diagrams for said modules.
-
The GND (ground) terminal point is not connected.
Wiring Diagram (Instrument Grounding)
The following figure shows the wiring (instrument grounding) for the 140 CFH 008 00 module.
NOTE:
-
If you use a single power supply, there will be no channel-to-channel isolation of the input points.
-
For the required jumper options for the 140 ACI 030 00 and the 140 AVI 030 00, see the wiring diagrams for said modules.
-
The GND (ground) terminal point is not connected.
Wiring Diagram (Chassis Grounding)
The following figure shows the wiring (chassis grounding) for the 140 CFH 008 00 module.
NOTE:
-
When using a single power supply, there will be no channel-to-channel isolation of input points.
