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.
| 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) |
| Operating temperature range | -20°C to +70°C (with suffix code) |
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.
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.
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.
