The Bill Validator has two types of input / output circuitry according to the existing interfaces:

isolated low voltage circuitry and TTL/CMOS-level non-isolated circuitry.

8.1. Isolated Pulse Interface

The input and output circuitry belonging to this interface are shown in the figure below. They

have the following specifications:

1. Isolated OUTPUT PULSE circuitry:

- normally open (NO) relay bounce free contact with optocouple electrical insulation;

- open circuit leakage current is not greater than 0.1 mA with applied voltage up to

50 VDC;

- resistance of the closed contacts is not greater than 100 Ohm;

- maximum load current is not more than 70 mA.

2. INHIBIT LINE input:

- electrically insulated optocouple input;

- input voltage to prohibit any banknote acceptance is not more than +0.5 VDC;

- input voltage to allow banknote acceptance is within the range: +3..+24 VDC with the current

not exceeding 24 mA.

The additional non-isolated TTL-level CREDIT PULSE output has exactly the same circuitry as
