        Features:

        • Accepts sixteen isolated 4 to 20 mA inputs with a 40 ms update period.
        • Supports individually selected two-wire or four-wire transmitter connections.
        • Provides ISA G3 environmental construction for operation from -20 to +70 deg C.
        This execution uses a signal-cable interface adapter and does not include explosion protection or standard HART communication. The sixteen channels share the documented module-isolation architecture.

        Process current is converted and refreshed for use by the ProSafe-RS safety logic while the module provides transmitter supply within the stated electrical limits. An identical additional module can be used for redundancy.

        Barrier selection and adapter-pin settings must be checked for every channel. Zener barriers are prohibited, and installations requiring intrinsic-safety separation must use an appropriate isolation barrier.

        Apter Power confirms supply after the suffix, barrier method and redundancy arrangement are reviewed.

        • Acquires safety-related 4 to 20 mA measurements from process transmitters.
        • Supports redundant analog input arrangements in ProSafe-RS instrumented functions.
        • Provides isolated signal collection in ISA G3 environments where conventional transmitters are used.
        • The documented operating range for the -S63 environmental execution is -20 to +70 deg C.
        • Accuracy drift is specified at +/-16 microampere for each 10 deg C temperature change.
        • Cabinet thermal design must keep the installed module within its stated operating boundary.
        • Input-to-system withstand capability is 1.5 kV AC for one minute.
        • Zener barriers are not permitted, so isolation barriers must be selected where segregation is required.
        • The suffix execution does not include explosion protection and must be applied accordingly.
        • The module is supplied in the documented ISA Standard G3 environmental execution.
        • Signal-cable connections and adapter pins must remain protected by the approved cabinet arrangement.
        • The non-explosion-protected version cannot be placed in a hazardous area without suitable external protection.
        Description
        Yokogawa SAI143-S63 is a sixteen-channel isolated analog input module for ProSafe-RS safety systems. It accepts 4 to 20 mA field signals, provides channel-level isolation and updates input data every 40 ms, supporting safety-related measurement acquisition from process transmitters. The 0 to 25 mA permissible range accommodates normal measurement and defined over-range conditions, while the isolated architecture limits the influence that one field circuit can have on the remaining safety inputs.

        Each channel can be arranged for two-wire or four-wire connection through the specified pin selection, and the module supplies transmitter power within the documented limits. The -S63 execution uses a signal-cable interface adapter and ISA G3 construction, making it suitable for the defined ProSafe-RS cabinet and environmental arrangement. Its specified accuracy, temperature drift and transmitter-supply characteristics support repeatable acquisition of pressure, flow, level and other process variables used by safety instrumented functions.

        An identical second module may be applied where the documented redundant configuration is required. Engineering should also account for the 0 to 25 mA permissible range, -20 to +70 deg C execution, absence of standard HART communication and the prohibition on Zener barriers; an isolation barrier is required where a barrier is needed. Channel wiring, adapter selection, system power demand and the 1.5 kV input-to-system withstand requirement should be checked against the safety-loop design before commissioning.

        Technical notes
        For SAI143-S63 intrinsically safe loops, use an approved isolation barrier rather than a Zener barrier; also set each interface-adapter pin for the actual two-wire or four-wire transmitter circuit.

        The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
        VIEW ALL FAQS
        How quickly does Yokogawa SAI143-S63 refresh its sixteen inputs?
        The official module data specifies a 40 ms update period for the analog input channels.
        How are two-wire and four-wire transmitters selected on Yokogawa SAI143-S63?
        The wiring mode is selected individually by pins on the signal-cable interface adapter.
        Why is a Zener barrier unsuitable with Yokogawa SAI143-S63?
        The manufacturer restriction excludes Zener barriers; an isolation barrier is required where intrinsic-safety segregation is needed.
        Can Yokogawa SAI143-S63 be configured redundantly?
        Yes. A redundant arrangement is supported by installing an identical additional module in the documented system architecture.
        What does the -S63 execution define for Yokogawa SAI143-S63?
        It identifies the signal-cable interface, no explosion protection and ISA G3 environmental execution.
        Which project details should accompany a Yokogawa SAI143-S63 inquiry?
        Include transmitter wiring type, barrier method, redundancy requirement and the exact interface-adapter arrangement.
