-
Teledyne Gas & Flame Detection
Syntel is an addressable loop system suitable for use in zone 1 and 2 hazardous areas. The complete addressable loo is fault tolerant operating normally with a short or open circuit. Syntel does not have a CPU, so there is no common failure point. It includes a standard OPC interface and can also be supplied by Modbus allowing easy integration with third party systems.Syntel stores alarm and calibration information in distributed non-volatile memory, hence there is no reliance on a centralized system.Syntel is ideal for installations where there is the possibility for future expansion. The system architecture allows very low cost expansion as cable runs to a central location are not needed.

Networked Absolute Inclinometer
T7
-
The T7 is available in several interface and protocol options. The physical interface can be RS232, RS485 or US Digital's CAN (Controller Area Network). The protocol can be either US Digital's serial protocol or Modbus RTU. The RS232 version supports a single T7 with up to 100 ft of cable. For users that need longer cable lengths or multiple T7s on a single bus, the RS485 or US Digital CAN (Controller Area Network) version can be used. The USD-CAN protocol allows a network of up to sixty-four T7s to be connected to a single host. Power for each T7 is supplied over the CAN network cable. The host accesses the USD-CAN T7s through US Digital's low cost CANA-232/CANA-485 adapter module. This module allows the host to access each T7 on the network using simple, easy serial port commands, just like the RS232 version. The RS485 version supports up to 32 T7s on the bus.
