Configured for single-loop control and programmable PID regulation within industrial process automation environments, the Yokogawa YS170-012 S3 (YS170-012 S3 Programmable Controller) provides direct physical/electrical execution.
| Parameter | Specification |
|---|---|
| Model | YS170-012 S3 |
| Brand | Yokogawa |
| Origin | Japan |
| Weight | 1.1 kg |
| Dimensions | 7.0 cm x 14.5 cm x 29.3 cm |
| Operating Temp | Standard industrial enclosure range (0 to 50 deg C implied) |

| Control Function | Programmable single-loop PID control with analog and digital I/O capabilities |
The controller executes precise analog loop control, processing 4-20 mA DC input and output signals interfacing directly with field transmitters and final control elements. Galvanic isolation across input/output channels and power terminals protects internal processing circuitry from ground loops and transient voltage surges. Built-in signal conditioning and internal math processing ensure stable loop regulation under fluctuating industrial process conditions.
Q: Does the YS170-012 S3 controller support battery backup for internal user-programmed memory retention during power outages?
A: Yes, an internal lithium battery or capacitor backup mechanism sustains user programs and calibration parameters during a complete loss of operating power.
Q: How are analog and digital field signals terminated at the rear of the controller housing?
A: Field wiring is terminated onto dedicated rear screw terminal blocks designed for secure connection of control loop cables and signal shielding.
