Digital process indicator
µ400P Terwin Instruments Ltd.

The model |j400P is a high performance process indicator/alarm
controller. User configurable input and output options allow this
instrument to be used in a wide range of industrial and research
applications, including the measurement of pressure, weight,
temperature from T/C's and RTD's, DC voltage or current loop inputs.
When used with extrusion melt pressure sensors that employ 6 wire 80%
negative shunt calibration such as the Terwin 2000 series transducers,
the |j400P provides a simple automatic self-calibration feature for
both zero and 80% of the applicable pressure range.
The p400P is provided with two alarm relays as standard and these
may be configured as low' or 'high' with direct or inverse action.
Additionally, delays in the relays action may be introduced (up to 20
seconds) and the relays may be latched with manual reset through
the front key pads. Optional outputs include Modbus/RTU RS-485 seri-
al communications and analog user configurable outputs of 0 - 5V,
0 -10V, 0 - 20mA or 4 - 20mADC. Also, an optional 24VDC output is
available for use with transmitters.
