Yokogawa ADV557 32-Channel 24 V DC Digital Output Module
Yokogawa ADV557 is a 32-channel isolated 24 V DC digital output module for FIO. It uses current-sink transistor outputs and is specified for pressure-clamp terminal support only; confirm the complete suffix and ATC5S terminal hardware before replacement.
Technical Specifications
Reference: Yokogawa GS 33K50F70-50E and GS 33J60F70-01EN. Confirm the complete installed suffix, certification requirements and terminal arrangement before replacement.
Replacement Checks Before Shutdown
The base model identifies a 32-channel 24 V DC output module. Compare the installed -S, protection-related and ISA G3 suffix positions before ordering.
ADV557 is specified for pressure-clamp terminal support only. Check the existing ATC5S terminal and field wiring before removing the installed module.
Use the 20.4–26.4 V DC field supply and keep each output within 100 mA at 26.4 V. Check the total load and common grouping before energizing.
Yokogawa specifies a spark-killer diode when ADV557 drives a DC relay. Verify relay suppression and the 16-channel common wiring before startup.
Product Image Display
Check the complete ADV557 label before transfer. This is a 32-channel digital output module, not the ADV159 input module or ADV559 compatible-ST output module.
Confirm the ATC5S terminal hardware and each field wire before a shutdown. ADV557 is not specified with a KS cable-adapter connection.
Review the 16-channel common groups, 24 V DC supply and DC-relay suppression before restoring the output circuit.
Confirm ADV557 Before Ordering
Send the complete module label, ATC5S terminal confirmation, required quantity and destination so the request can be checked against the installed FIO output configuration.
Frequently Asked Questions
What exactly is Yokogawa ADV557?
ADV557 is a 32-channel isolated 24 V DC digital output module for FIO. It provides current-sink transistor outputs and is specified for pressure-clamp terminal support only.
How many output channels does Yokogawa ADV557 provide?
Yokogawa ADV557 provides 32 digital output channels. Its normal load specification is 24 V DC at 50 mA, with a maximum load of 100 mA per channel at 26.4 V.
Which terminal block is required for Yokogawa ADV557?
ADV557 uses the ATC5S pressure-clamp terminal. The official module/terminal table does not assign a KS cable-adapter option to this model.
What supply range applies to Yokogawa ADV557?
The specified external field supply is 20.4–26.4 V DC. The output ON voltage is 2 V DC maximum and the OFF leakage current is 0.1 mA maximum.
Does Yokogawa ADV557 support pulse or time-proportional output?
No pulse or time-proportional designation is listed for ADV557. Yokogawa lists a status-output function with a response time of 3 ms or less.
How are Yokogawa ADV557 output commons grouped?
The output commons are grouped every 16 channels. The withstand specification is 2 kV AC between output and system, and 500 V AC between commons.
What should be checked before replacing Yokogawa ADV557?
Compare the full suffix code, terminal type, field supply, individual load, 16-channel common wiring and any explosion-protection requirement before power-up.
Why is a spark-killer diode relevant to Yokogawa ADV557?
Yokogawa specifies a spark-killer diode when the module drives a DC relay. The diode limits relay-switching stress on the output circuit.
