Pre select counter/ high frequency monitor dislay and count a pre-set number of pulses dislay and monitor frequencies up to 10000Hz
1 RELAY
This device may be configured for counting or frequency monitoring functions.
Using the "save" function, the state of the counter is saved to non-volatile memory during power failures. This allows the device to continue from where it left off before the power was removed.
A 10V - 24V DC supply (± 30mA) is included for use with NPN proximity switches.
Pulses can be acknowledged when the pulse pins are either shorted OR released.
A pre-scaler of up to 200 is included. (the device reads the "pre scale" amount of pulses before updating the counter value).
The post-scaler multiplies the pulses received by up to 200.
Pulses may be displayed as lapsed (up-counting), remaining (down counting) or frequency (even if configured for counting).
Using the reset timer the device can automatically be reset between 0.1 and 99.9 seconds after the pre-set number of pulses have been counted. This eliminates the need to generate reset pulses manually.
