1.2 TECHNICAL DATA
1 .GENERAL DESCRIPTION
Supply voltages Board supply: 17vac +15% -25% - 120mA
Periphery supply: 22vdc +15% -25%
Inputs Each input has a led to indicate its status – all inputs are optically isolated
Input acve voltage level is 22vdc
Control outputs Each output has a led to indicate its status – all outputs are dry relay contacts
Rated at 250Vac 10A
Spare outputs Each output has a led to indicate its status – all outputs are opcally isolated
Output voltage level is 0vdc (GND) when acve
Call terminals Each call has a led to indicate its status
Each call terminal consists of a combined input/output which is opcally isolated
Call acve voltage level is zero volts (GND)
Call terminals are capable of driving lamps up to 3 was operating on 22vdc
Each call terminal is protected by an additional output transistor
The + and – supplies of Car and Hall are short circuit protected
Indicator outputs Each output has a led to indicate its status – all outputs are opcally isolated
For A,B,C,D,E, LED On: Output voltage level is 22vdc (P)
For arrow up and arrow down LED On: Output voltage level is 0vdc (GND)
Connecon Screw type, plug-in connectors
Norms Conforms to EN81
Care should be taken to add a freewheeling diode in parallel with the coil of each DC contactor or DC relay driven from the board.
