EXPANSION BOARD (I/O)

IO expansion board also known as Input-Output expansion board consists of 20 relays and 8 opto-isolated inputs. It works on 12 VDC supply. Each of the relay consist of three terminals on the board namely N.O. (Normally Open), N.C. (Normally Closed), and CM. (Common). All the relays give out dry contacts on the board. In total there are 60 terminals on the panel for 20 relays.

IO Expansion Board is a separate Panel consisting of addon relays which acts as switch. We can program through the iWatch Access Control Panel to get the desired output. IO Board is also known as Elevator Control Board. It is used to regulate n numbers of doors just by the selection of Jumpers on the main iWatch Access Control Panel.

SPECIFICATION:

I/O Board Power : 12V DC.

Nominal coil Voltage : 12 VDC (Must operate Voltage 9 VDC).

Operational temperature range – 40°C to 85°C.

Power Connection- Power can be connected to panel at either PWRT1 or PWRT2.

PWRT1 is a two terminal block where Pin1 is 12V DC and Pin2 is Ground.

PWRT2 is a two pin header where Pin1 is 12V DC and Pin2 is Ground.

FEATURES:

Maximum three I/O boards can be connected to a single Host Controller using CS1, CS2 and CS3.

These chip selects can be selected using jumper JP5.

CS1 will be selected if jumper is on 1 and 2.

CS2 and CS3 will be selected if the jumper is on 2 and 3, and, 5 and 6 respectively.
