TOCSIN 903 ATEX Standalone Gas Detector Transmitter
The TOCSIN 903 ATEX Control Panel provides a local display and control facility for the TOCSIN 102 series or or pellistor gas detectors, which are used in Zone 1 and 2 hazardous areas.
It is equipped as a 4-20mA process transmitter and can also be fitted with serial digital addressable capability either using the IGD data highway to integrate to a TOCSIN I700 or TOCSIN 920 Series Control Panels, or optionally as a HART device.
The unit is fully compatible with TOCSIN 700 and TOCSIN 920 control panels, which offer both addressable and analogue inputs as well as Modbus serial outputs. More conventionally the TOCSIN 903 can be interfaced directly into DCS / BMS systems using its 4-20mA process output.
An alarm relay output card is also available, and to complement the system, a range of accessories, calibration sets and audio visual alarms can be provided.
Available sensor types:
- TOC 30 Annunciator Control Panel Accessory
