Seriol Remote Terminal Units
S250 Programmable Telemetry Controllers from our Seriol range for industrial monitoring control and data acquisition.
S250 Seriol
Based on S500 technology the S250 now reduces the cost of telemetry data acquisition to a level previously unaffordable. Packed in a small self contained IP30
enclosure the unit is suitable for information into third party equipment or routine into IP66 enclosures for direct plant installation.
These data acquisition/controllers are programmable in Sercal or SerGraf-1131 for simple or complex control, monitoring, telemetry and data logging applications.
S250 Seriol Telemetry Controllers and Power Supplies
From concept the S250 has been designed to meet the requirements of unmanned remote telecontrol. The functionality is enhanced with comprehensive diagnostic facilities
accessible both remotely and locally. Environmentally the S250 meets demanding EMC standards experienced in such locations and will operate in ambient temperatures of -10°C to +80°C.
The basic assembly is designed for mounting in third party control and electrical panels. It is packaged in an IP30 rated enclosure which may be fitted into an industrial IP55 or IP66
cabinet for outdoor service.
Standard isolated plant interfaces are 8 digital inputs, 4 analogue inputs and 4 digital outputs. 24V DC supply is available for input/output exitation.
Expansion units are available which provide capacity for using the S500 range of input/output and communication modules to increase the capability and functionality.
CMOS technology is employed to reduce power consumption. Primary power is from mains 230/110 volts ac (jumper configurable) 45-65Hz. Secondary power is provided by a 12 volt sealed
lead acid battery.
The S250 will monitor charge/discharge current, battery voltage, mains and internal logic supplies. A unique feature of the S250 is to provide an integral battery self test facility
enabling early detection of the secondary power battery reaching the end of its serviceable life.
An externally mounted power supply unit option offers higher power capability for both S250 power and battery recharge whilst retaining the features of the internal
power supply version. The internal plant interface supply may be switched off to facilitate input/output testing and to save power. S250 can power down when not scanning plant or communicating
in order to conserve power. In power down mode current useage is less than 200µA. S250 will wake on:- Alarm from internal real-time clock, Man machine interface activation, Incoming
call on communications ports, Mains power reconnect or Keypad operation.
Units are available for DC power and battery only applications.
S250 Seriol Telemetry Communications Interfaces
 A range of communication options are available supported
by tried and tested proprietary communications protocols offered by CSE-Seprol. In addition, third party protocols are also supported or can be integrated in to the S250 firmware.
The base assembly is fitted with an integrated communications interface.
The range of options include:-
- RS232/RS422/RS485
- PSTN V21/V22/V22bis
These modules enable a variety of communications media to be used to support telemetry communications over
- PSTN
- GSM
- Leased Line
- Private Wire
- Radio (Licensed)
- Radio (Un-licensed)
- Microwave
- Fibre Optic
- Securestream 300 (CSDN)
- ISDN
- Packnet
- Expansion Network (to further S250's)
In addition the S250 supports the following PLC protocols
- Modbus
- Allan Bradley
- Mitsubishi
S250 Seriol Plant Input/Output Interfaces
 The expanded S250 can accept interfaces from the S500 range
of modules to provide input and output functions.
The range includes
- Digital inputs (status and counting)
- Event inputs with 1mS resolution
- Digital outputs (Volt free contact and solid state)
- Analogue inputs 14 bit (voltage and current)
- Analogue outputs 12 bit (Voltage and current)
- Low power digital input (Shaft encoder/tipping bucket/wake on event) S250 Seriol Secondary Enclosures
The S250 is packaged in a IP30 rated housing and is suitable for mounting into existing or new secondary enclosures. CSE-Seprol are able to provide a range of
standard secondary enclosure of ratings from IP55 to IP67. Sizes vary from 300mm(w)x300mm(h)x200mm(d) to 600mm(w)x600mm(h)x350mm(d) dependent on configuration and additional equipment
housed.
