Product Introduction
The Yokogawa SNT511 is an Optical ESB Bus Repeater Slave Module designed to extend the ESB bus transmission distance in ProSafe-RS systems. Paired with the master module (SNT411), it converts electrical ESB signals to optical signals for long-distance, noise-resistant communication over fiber-optic cables, supporting distances up to 50 km.
Technical Specifications
| Parameter | Value |
|---|---|
| Function | ESB bus optical transport (Vnet/IP) |
| Connection method | Star and chain type supported |
| Maximum connecting stages | 2 |
| Transmission distance | 5 km to 50 km |
| Current consumption | 0.5 A |
| Dimensions (W x H x D) | 142.5 × 130 × 32.8 mm |
| Weight | Approx. 0.3 kg |
| Compliance | ISA G3 standard (with suffix code) |

Applications
The SNT511 is ideal for:
-
Safety control systems requiring extended ESB bus distances.
-
Environments prone to electrical noise where fiber optics improve reliability.
-
ProSafe-RS installations with distributed safety nodes over large facilities.
Advantages
-
Supports both star and chain connection topologies.
-
Extends communication distance up to 50 km.
-
Compact and lightweight, easy to install.
-
Compatible with Yokogawa’s ProSafe-RS ecosystem.
-
Enhanced immunity to electromagnetic interference.
FAQs
Q1: What is the main purpose of the SNT511?
A1: It serves as the slave end of an optical repeater pair, extending ESB bus signals over fiber.
Q2: Can the SNT511 operate alone?
A2: No, it must be paired with a master module like the SNT411 or S2EN501.
Q3: What topologies does it support?
A3: Both star and chain connection topologies.
Q4: What is the maximum transmission distance?
A4: Up to 50 km over optical fiber.
Q5: Does it require an external power supply?
A5: It is powered through the system slot with a current draw of 0.5 A.
Q6: What is the recommended mounting method?
A6: Install in designated slots in SNT10D or compatible racks, observing temperature and spacing guidelines.
Q7: Is it suitable for hazardous areas?
A7: Explosion-protected variants are available (suffix code -E).
Q8: Can it connect to multiple slave modules?
A8: One master can connect up to two slave stages.
Q9: What optical attenuation is recommended?
A9: Ensure optical loss of 3–4 dB between modules; use attenuators if necessary.
Q10: Is it compatible with older ProSafe-RS systems?
A10: Yes, provided the system firmware is R1.03 or later.
