The OdaTrak™ 4 to 20mA adapter was primarily designed as an interface between the OdaLog® gas Logger and industrial control systems for the purpose of continuous, real-time optimisation of chemical dosing odour control systems and connection to telemetry and other systems.Specifications - OdaTrak™ 4 to 20mA Adapter
The OdaTrak™ 4 to 20mA adapter reads gas concentration data sent from an OdaLog® gas Logger over a fibre optic cable, deciphers the data, and then outputs the corresponding 4-20mA loop analogue signal. This allows the OdaLog® unit to be interfaced to control and telemetry systems providing real-time gas data. This signal could be used to optimise chemical dosing, trigger alarms, control ventilation fans, or interface to telemetry systems etc. The OdaLog® Logger can still be used as a standalone data-logging instrument if required.
Special features of the OdaTrak™ 4 to 20mA adapter include:
Fault detection - The OdaTrak™ has the ability to detect for a loss of OdaLog® data over a predetermined period of time and will output a fault state on the 4 to 20mA line when that time limit has expired. The fault current is 3.5mA.
Suitable for harsh environments - The fibre optic cable connector features an O-ring seal to prevent the ingress of dust and liquid, and the OdaTrak unit is fully sealed.
Quick and easy installation - The OdaTrak has an M20 thread machined as part of the housing. Simply mount through a 20mm hole or threaded junction box entry.
Data logging - All of the usual OdaLog® functions, including data logging, are available while the 4 to 20mA link is active.
