Inputs A and B in Unidirectional mode
In the two Unidirectional modes, the count is incremented or decremented by input A,
whilst the direction is dependent on input B.
In Unidirectional High mode, both inputs are high speed inputs, suitable only for
electronic signal sources, eg. transistors, proximity switches, encoders.
In Unidirectional Low mode, both inputs are low speed inputs (30Hz max), suitable
for contact closure sources, eg. microswitches, relays, pushbuttons. Any contact
noise is removed by filtering. They can also be used for electronic signal sources.
Inputs A and B in Quadrature mode
In Quadrature mode, the count is incremented or decremented depending on the phase
difference between input A and input B.
In this mode, both inputs are high speed inputs, suitable only for electronic signal
sources, eg. transistors, proximity switches, encoders.
Input K (Keyboard Inhibit) and Input R (Reset)
Both inputs are low speed inputs as described above.
Cables
Maximum wire size the connector can accept is:
2.5mm 2 cross sectional area; 1.8mm diameter. (equivalent 13 AWG solid wire)
Any signal cables connected to this device must not exceed 30 metres in length.
If signal cables are installed that are routed outside the building, it will be
necessary to install additional surge protection devices.

Power Supply (see pages 37 & 38)
The counter can be powered by AC mains, in which
case pins 1 and 2 provide an Auxilliary supply
(+12V DC +20% -0%, 75mA max recommended) which
can be used to power sensors if required.
Alternatively, the counter can be powered by an
external DC source (12-24V DC ±10%, 100mA),
connected to pins 1 and 2.
