Current command conversion
Controller output words become eight 4 to 20 mA loop currents, with each channel updating every 10 ms and settling through the documented response.

CENTUMI/OMODULE
01
Model Profile
Yokogawa ASI533-S00 S1 is an eight-channel isolated 4 to 20 mA analog output module with built-in intrinsic-safety barriers for CENTUM field I/O. It converts controller output values into current loops while maintaining an isolated interface between each hazardous-area circuit and the control-system side.
Through the ATSS3 pressure-clamp terminal, Yokogawa ASI533-S00 S1 sends each output current to its assigned field device and supports HART communication on the same loop. The receiving load remains within 750 Ω at 20 mA and 600 Ω at the 23 mA maximum so the module can maintain its commanded current.
The intrinsic-safety behavior of Yokogawa ASI533-S00 S1 links all channels to the module protection condition: short circuits on two or more field channels cause all channels to fail for intrinsic safety. Field wiring, equipotential bonding and associated apparatus must therefore follow the approved system design.

Product Functions
ASI533-S00 S1 combines analog command conversion, loop communication and barrier separation in one eight-channel output path.
HART on the loop
HART communication shares the connected current loop, allowing device variables and on-demand communication without a second field cable.
Open-loop supervision
The module detects a current loop that falls below the circuit-open threshold, giving the controller a fault clue distinct from the commanded process value.
04
Safety and Compliance
The built-in barrier is part of an intrinsically safe system and must be evaluated with the connected field circuit, not as a standalone approval claim.
Associated apparatus match
Compare the ASI533-S00 S1 entity parameters with the field device, cable capacitance and inductance before accepting the loop design.
Multiple-short behavior
Two or more shorted field channels cause all channels to fail for intrinsic safety, so grouped output loss requires inspection of every connected loop.
Terminal discipline
Use the specified ATSS3 terminal, maintain the approved separation and bonding arrangement, and commission one loop at a time under the site safety procedure.

Product Help
01What load can Yokogawa ASI533-S00 S1 drive at full current?
Yokogawa ASI533-S00 S1 supports 0 to 750 Ω at 20 mA and 0 to 600 Ω at its 23 mA maximum; cable and receiver resistance are included in that loop total.
02Why can all outputs on Yokogawa ASI533-S00 S1 fail after field shorts?
Yokogawa ASI533-S00 S1 is designed so short circuits on two or more field channels cause all channels to fail for intrinsic safety; inspect every loop before resetting service.
03Which terminal block belongs to Yokogawa ASI533-S00 S1?
Yokogawa ASI533-S00 S1 uses the ATSS3 pressure-clamp terminal family; the single or dual-redundant form must match the installed arrangement.
04Can a standard analog output card replace Yokogawa ASI533-S00 S1?
No. Yokogawa ASI533-S00 S1 includes barrier parameters, isolation and approved terminal arrangements that a standard non-barrier analog output does not reproduce.
05How should HART be checked on Yokogawa ASI533-S00 S1?
For Yokogawa ASI533-S00 S1, confirm the analog loop first, then verify compatible node firmware, HART configuration and direct device connection before troubleshooting communication.
06What should be recorded before removing Yokogawa ASI533-S00 S1?
Before removing Yokogawa ASI533-S00 S1, record channel assignments, loop polarity, terminal identity and hazardous-area circuit references, then isolate the approved power sources.
