Analog to Pulse BLI152

The LI152 is an analogue to pulse converter that supports a variety of input signals ranging from 100mV up to 100Vdc and 1mA up to 1Adc full scale.

Description

The BLI152 is an analogue to pulse converter that supports a variety of input signals ranging from 100mV up to 100Vdc and 1mA up to 1Adc full scale. The output is typically a DC pulse, adjustable from 0.3 p/min up to 600p/min. This pulse is available as an internally sourced 24Vdc pulse, open collector or potential-free relay contact. The analogue input signal is initially converted to a linear pulse signal to about 500Hz FS. A binary counter is then used to accurately divide down to the desired output pulse rate. Coarse setting is achieved by internal coding plug on an 11-point range selector. Final calibration is trimmed using the front accessible ‘offs’ and ‘span’ 15-turn trim adjustments. A test socket is available for accurate zero setting. To overcome accumulative errors over long time spans of zero operation the BLI152 features ZERO LOCKOUT. This lockout inhibits any pulses being generated below 2% of input span. The lockout range can be extended up to 10% of input span if required. For special applications the BLI152 can be aranged for reverce action. All outputs are available simultaneously. scale input. All outputs are available simultaneously. Inserting a link on terminals 9 and 8 enables the relay output. Terminal 3 features an auxiliary output, which can be used for loop-powered transmitters relay contact or opto-coupler.
