Description
The DO820 is an 8 channel 230 V a.c./d.c. relay (NO) output module for the S800 I/O. The maximum output voltage is 250 V a.c./d.c. and the maximum continuous output current is 3 A. All outputs are individually isolated. Each output channel consists of optical isolation barrier, output state indication LED, relay driver, relay and EMC protection components. The relay supply voltage supervision, derived from the 24 V distributed on the ModuleBus, gives an error signal if the voltage disappears, and the Warning LED turns on. The error signal can be read through the ModuleBus. This supervision can be enabled/disabled with a parameter.
Features and benefits
8 channels for 230 V a.c./d.c. relay Normal Open (NO) outputs
8 isolated channels
Output status indicators
OSP sets outputs to predetermined state upon error detection
The programmable controller uses the I/O expansion interface to connect the I/O expansion unit with the basic unit of PLC. When the input or output points of the basic I/O unit are not enough, the I/O expansion unit can be used to expand the switching I/O points and increase the analog I/O terminals.
Peripheral Interface
The peripheral interface circuit is used to connect the hand-held programmer or other graphic programmer and text display, and can form the control network of PLC through the peripheral interface. PLC is connected to the computer through PC/PPI cable or MPI card through RS-485 interface, which can realize programming, monitoring, networking and other functions.
Power Supply
The function of the power supply unit is to convert the external power supply (220V AC power supply) into the internal working voltage. The externally connected power supply converts the AC/DC power supply into the working power supply (DC 5 V, positive and negative 12 V, 24 V) required by the internal circuit of the PLC through a special switch type regulated power supply inside the PLC, and provides 24V direct current power supply for external input elements (such as proximity switches) (only for the use of input terminals), while the power supply driving the PLC load is provided by the user.
