SAITEL Remote Terminal Unit & Controller

Compact, scalable, powerful communications

Part of PowerLogic™

The high-performance, versatile, scalable and compact platform for secure automation

and communication applications.

Features

pSaitel is a highly-evolved field device, offering a solid and powerful platform for data

acquisition, communication, automation and IED integration, including backplane and

DIN rail based solutions.As a remote terminal unit, bay controller or protocol converter,

Saitel is the compact solution to countless applications installed in demanding 

electromagnetic conditions.In addition to the traditional input/output (I/O) management,

Saitel acts as a powerful communication gateway, an advanced measurement center and

a fast automation processor.Based upon an extendable distributed architecture and

featuring enhanced functionality and power, Saitel Family offers:/pp /ppThe ability to

monitor and control thousands of I/O points./pp /ppOperational redundancy for power

supply, CPU, communications channels, or for the entire system (supporting automatic

failover with hot-swap)./pp /ppExtensive library of standard and legacy protocols for

information exchange between multiple masters and RTU./pp /ppInput/Output acquisition

modules with signal conditioning and integrated time synchronization (1 ms) and

independent time stamping./pp /ppIEC 61850 technology that is certified as Class A by

the independent testing laboratory KEMA for both IEC 61850 server and client interfaces.

Cybersecurity features and functions can support a utility’s NERC Critical Infrastructure

Protection (CIP) compliance.

The SM_DO16R module includes:

• 16 independent free-contact digital outputs (DO) in two independent blocks. Each DO can be

configured as:

o Single: pulsed (fixed time) or preset (latched).

o Double: pulsed or preset.

• All DO are SPST (Single Pole Single Throw) or NO (Normally open).

• External polarization of DO for each block. According to the P/N, DO signals will be polarized

using 24 VDC or 48 VDC.

• Polarization level is monitored for each block.

• An advanced command safety mechanism is used to control field operation.

• Autocheck of DOs every time that the polarization is reset.

• Control by external watchdog for unsafe situations. The module goes to a safe mode

(commands are blocked) if certain conditions are not met.

• Address and communication rate in the bus are setting using microswitches located on the rear

side.

• 20 LED indicators giving information about the status of the module and each DO.

• The software in the module can be upgrade remotely, from the CPU.

• Isolation of 2.2 kV between field connectors and the controller block.

This module implements hot-swapping function, that is, it can removed and installed on the

backplane while the RTU is working without affecting the proper functioning of the system.

The diagram below illustrates the functional blocks integrated in the SM_DO16R module:

• I/O to the bus: Connection to the bus in the backplane to share information with the CPU.

• LEDs: There are 20 LED indicators on the module’s front side which provide information about

the module and the output signals.

• Synchronization: SM_DO16R is synchronized via a message received from the CPU that

includes information about the time. Therefore, the module will be synchronized with the

synchronization source accuracy used for the CPU.

The Saitel DP platform is a complete set of devices provided by Schneider Electric for real-time

control applications and power line automation. It is a high-technology platform which gives a

solution to the business areas of Schneider Electric.

The following figures show a Saitel DP in chassis (left) and in backplane (right).

Saitel DP’s design has been optimized to meet the most demanding requirements of multiple

sectors:

• Cost-efficiency, minimum downtime, and compliance with electrical safety, electromagnetic

compatibility and environmental standards.

• Safety and reliability requirements for power, gas, water, residual water supply, etc.

• Centralized monitoring and control of geographically distributed systems which support

hierarchical data acquisition and redundant networks.

• Local monitoring and control with data sharing capabilities of plant-distributed devices.

• Quick troubleshooting by means of programmable automation execution.

• One of the most remarkable features of Saitel DP is its modular design. All I/O, CPU, power

supply and communication modules have an identical format, sharing the same enclosure.
