- Commodity name: JD-MD60S type monitoring module
The JD-MD60S type monitoring module is used to monitor and collect passive switching (normally open) signals, such as action signals of pressure switch, water flow indicator, temperature sensing cable, etc. It communicates with the JD-M108 fire control equipment monitoring device (hereinafter referred to as monitoring device) produced by our company through the two buses and transmits the state to the monitoring device. The JD-MD60S monitoring module occupies 5 bus addresses (one switch occupies one address).
Main Features
Two buses, no polarity
Can receive five passive switch contact signals
Account for 5 address points (a switch occupies an address), using electronic coding address (1~239), only need to encode the first address, the remaining 4 addresses add 1 at a time.
With line fault detection function, can detect passive switch contact line failure -
