Hardware Specifications

Parameter Specification
Model SAT145-S63/PRP S2
Brand Yokogawa
Origin Japan
Weight 0.47 kg
Dimensions Standard ProSafe-RS Vnet/IP card form factor (approx. 130 mm x 30 mm x 150 mm)
Operating Temp -20 to 70 deg C
Power Consumption 5 V system: 400 mA; 24 V system: 200 mA
Signal Conditioning Channel-to-channel isolation with integrated 4-20 mA HART loop protocol support

4-20 mA HART Loop Protocol

The module executes precise analog-to-digital conversions across configured loop circuits while preserving superimposed digital HART communication packets. Channel-to-channel galvanic isolation prevents ground loop interference across distributed field transmitters, ensuring signal integrity under high electromagnetic interference conditions. Cold junction compensation and internal voltage references are continuously monitored by firmware diagnostics to validate conversion accuracy.

Frequently Asked Questions

Q: Does the SAT145-S63/PRP S2 support online hot-swapping during active plant operation?

A: Yes, when deployed in a designated redundant pairing configuration (/PRP S2), the secondary module can be extracted and replaced without interrupting the primary safety loop execution.

Q: How is the backplane current draw calculated for power distribution planning?

A: Power consumption is split across internal rails, drawing a maximum of 400 mA from the 5 V system bus and 200 mA from the 24 V system bus per module.

Field Installation Guidelines

  • Mount the module directly onto the designated ProSafe-RS baseplate slot, ensuring correct backplane pin engagement prior to securing the retaining screws.
  • Terminate field wiring onto the dedicated pressure-clamp terminal blocks, maintaining twisted-pair shielding grounded at a single point to mitigate induced noise.
  • Verify that ambient panel temperatures remain within the specified range of -20 to 70 deg C with adequate vertical clearance for thermal dissipation.
