Trumeter 7932 Counter modules 79 series Assembly dimensions 45 x 45 mm 7932 数据表

These are high speed inputs (10kHz max), suitable only for electronic signal

sources, eg. transistors, proximity switches, encoders.

These 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.

Maximum wire size the connector can accept is:

2.5mm

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% 
-10%, 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.
