PolyGard®2 Gas Controller Expansion module EP-06-X00 GasAlarm
Expansion module with four analog inputs (4 to 20 mA), four alarm relays with potential-free SPDT contacts and two analog outputs (4 to20 mA) for the connection to the PolyGard®2 Gas Controller GC-06.
Up to seven expansion modules can be connected either centrally at the controller or distributed anywhere along the communication bus. For the field bus output there is an integrated overload and reverse polarity protection. A further field bus output with repeater function is provided in addition.
Discontinuity and functionality control of the external warning devices is available as an option for alarm relays AR-03 and AR-04.
Expansion of the analog inputs and outputs, as well as of the alarm relays of the gas controller system GC-06.
