Control Output Backup Function |
| The control output backup function comes standard with YS1000 series controllers (YS1700 and YS1500) and the Manual Station for MV Setting (YS1360). |
| Dual CPU |
|
 |
| With dual-CPU construction (main CPU and display CPU), manual control capability and display continues even if an abnormality occurs on one of the CPUs. If controller self-diagnostics detects a control circuit failure, the controller can suspend analog/digital output, switch to manual mode and allow manual control by operator. |

| Manual operation-"hard manual" |
|
| Independent manual override is built into the control circuits, ensuring that control output can continue even when a control circuit including the CPU experiences a problem. |

| Battery free memory backup |
 |
|
|
| Nonvolatile memory is used for memory backup. Service life is improved because no batteries, backup capacitors, or other components are used. |
| AC/DC power supply resists powerline fluctuations. |
 |
|
|
| The AC/DC (100 V /24 V ) power supply powers the instrument to provide consistent performance.Also accepts DC power regardless of polarity (specify 220 V power supply when ordering). |
