On site linkage output conversion module
Working voltage: The power supply mode is DC24V
Sampling method: This module is mainly used to bind multiple probe IDs. The module adopts a four wire type with a power supply voltage of 24V. The module needs to be connected to the RS485 communication line between the bus type combustible gas controller and the matching combustible gas detector to monitor its communication data.
If a detector bound to an ID triggers a low limit alarm during the collection process, the passive relay switch of the expansion module can switch from the normally closed point to the normally open point; When a high limit alarm occurs.
the 24V active relay of the expansion module switches from the normally closed point to the normally open point.
